Abstract
In this study, CM-5 spectrophotometer and Heracles NEO ultra-fast gas-phase electronic nose were used to analyze the changes in color and odor of vinegar-processed Cyperi Rhizoma(VPCR) pieces. Various analysis methods such as DFA and partial least squares discriminant analysis(PLS-DA) were combined to identify different processing degrees and quantify the end point of processing. The results showed that with the increase in vinegar processing, the brightness parameter L~* of VPCR pieces decreased gradua-lly, while the red-green value a~* and yellow-blue value b~* initially increased and reached their maximum at 8 min of processing, followed by a gradual decrease. A discriminant model based on the color parameters L~*, a~*, and b~* was established(with a discrimination accuracy of 98.5%), which effectively differentiated different degrees of VPCR pieces. Using the electronic nose, 26 odor components were identified from VPCR samples at different degrees of vinegar processing. DFA and PLS-DA models were established for different degrees of VPCR pieces. The results showed that the 8-min processed samples were significantly distinct from other samples. Based on variable importance in projection(VIP) value greater than 1, 10 odor components, including 3-methylfuran, 2-methylbuty-raldehyde, 2-methylpropionic acid, furfural, and α-pinene, were selected as odor markers for differentiating the degrees of vinegar processing in VPCR. By combining the changes in color and the characteristic odor components, the optimal processing time for VPCR was determined to be 8 min. This study provided a scientific basis for the standardization of vinegar processing techniques for VPCR and the improvement of its quality standards and also offered new methods and ideas for the rapid identification and quality control of the end point of processing for other traditional Chinese medicine.

Abstract
The weight coefficients of appearance traits, extract yield of standard decoction, and total content of honokiol and magnolol were determined by analytic hierarchy process(AHP), criteria importance though intercrieria correlation(CRITIC), and AHP-CRITIC weighting method, and the comprehensive scores were calculated. The effects of ginger juice dosage, moistening time, proces-sing temperature, and processing time on the quality of Magnoliae Officinalis Cortex(MOC) were investigated, and Box-Behnken design was employed to optimize the process parameters. To reveal the processing mechanism, MOC, ginger juice-processed Magnoliae Officinalis Cortex(GMOC), and water-processed Magnoliae Officinalis Cortex(WMOC) were compared. The results showed that the weight coefficients of the appearance traits, extract yield of standard decoction, and total content of honokiol and magnolol determined by AHP-CRITIC weighting method were 0.134, 0.287, and 0.579, respectively. The optimal processing parameters of GMOC were ginger juice dosage of 8%, moistening time of 120 min, and processing at 100 ℃ for 7 min. The content of syringoside and magnolflorine in MOC decreased after processing, and the content of honokiol and magnolol followed the trend of GMOC>MOC>WMOC, which suggested that the change in clinical efficacy of MOC after processing was associated with the changes of chemical composition. The optimized processing technology is stable and feasible and provides references for the modern production and processing of MOC.

Effects of different steaming times on the composition, structure and immune activity of Polygonatum Polysaccharide. JOURNAL OF ETHNOPHARMACOLOGY 2023; 310:116351. [PMID: 36914038 DOI: 10.1016/j.jep.2023.116351] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Revised: 02/23/2023] [Accepted: 03/01/2023] [Indexed: 06/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As a commonly used traditional Chinese herbal medicine, Polygonati Rhizoma has high medicinal value, it can enhance the immune capacity of the body, regulate the metabolism of blood glucose and lipids, treat weakness of the stomach and intestines and physical fatigue, and so on. There are three plant varieties of Polygonati Rhizoma recorded in Chinese Pharmacopoeia, including Polygonatum sibiricum Red., Polygonatum kingianum Coll. et Hemsl. and Polygonatum cyrtonema Hua, compared with the first two, Polygonatum cyrtonema Hua is less studied. Polygonatum cyrtonema Hua is one of the basal plants of the Chinese herb Polygonati Rhizoma, that strengthens the spleen, moistens the lungs, and benefits the kidneys. Polygonatum polysaccharide is the main active substance of Polygonatum cyrtonema Hua, which has various biological effects of regulating immune system, anti-inflammatory, anti-antidepressant, antioxidant and other effects. AIM OF THE STUDY In order to analyze the necessity and scientificity of multiple cycles of steaming during the traditional nine-steaming and nine-drying process of the concoction of Polygonatum, we investigated the changes in the composition and structure of polysaccharides, and explored its immunomodulatory activity and molecular biological mechanism. METHODS The structural characterization and molecular weight of polysaccharides were studied by scanning electron microscope (SEM), high-performance size exclusion chromatography-evaporative light scattering detector (HPSEC-ELSD) and Matrix.assisted laser resolutionu ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The composition and proportion of monosaccharides were determined by PMP-HPLC method. A mouse immunosuppression model was established by intraperitoneal injection of cyclophosphamide to compare the immunomodulatory effects and mechanisms of different steaming times of Polygonatum, The changes of body mass and immune organ indices of mice were measured; the secretion levels of interleukin-2 (IL-2), interferon γ (IFN-γ) and the expression levels of immunoglobulin M (IgM) and immunoglobulin A (IgA) in serum were determined by enzyme-linked immunosorbent assay; and then flow cytometry was used to detect T-lymphocyte subpopulations to evaluate the differences of immunomodulatory effects of polysaccharides during the processing and preparation of Polygonatum. Finally, the Illumina MiSeq high-throughput sequencing platform was used to analyze short-chain fatty acids and to investigate the effects of different steaming times of Polygonatum polysaccharides on immune function and intestinal flora in immunosuppressed mice. RESULTS The structure of the Polygonatum polysaccharide with different steaming times changed significantly, the relative molecular weight of Polygonatum polysaccharide decreased significantly, and the monosaccharide composition of Polygonatum cyrtonema Hua with different steaming times was the same but the content was different. The immunomodulatory activity of the Polygonatum polysaccharide was enhanced after concoction, which significantly increased the spleen index and thymus index, and increased the expression of IL-2, IFN-γ, IgA and IgM. The CD4+/CD8+ ratio of Polygonatum polysaccharide also increased gradually with different steaming times, indicating enhanced immune function and significant immunomodulatory effect. The content of short-chain fatty acids in the feces of mice in both six steaming six sun-drying of Polygonatum polysaccharides (SYWPP) and nine steaming nine sun-drying of Polygonatum polysaccharides (NYWPP) groups increased significantly, including the content of propionic acid, isobutyric acid, valeric acid, and isovaleric acid, and also had a good effect on the regulation and improvement of microbial community abundance and diversity, SYWPP and NYWPP increased the relative abundance of Bacteroides and the ratio of Bacteroides and Firmicutes (B:F), while SYWPP significantly increased the abundance of Bacteroides, Alistipes and norank_f__Lachnospiraceae, but the effect of raw Polygonatum polysaccharides (RPP) and NYWPP was not significant than SYWPP. CONCLUSION Overall, both SYWPP and NYWPP could significantly enhance the immune activity of the organism, improve the imbalance of intestinal flora in immunosuppressed mice, and increase the content of intestinal short chain fatty acids (SCFAs), it is noteworthy that SYWPP has a better effect on the improvement of the immune activity of the organism. These findings can explore the stage of the concoction process of Polygonatum cyrtonema Hua to achieve the best effect, provide a reference basis for the development of quality standards, and at the same time promote the application of new therapeutic agents and health foods in raw and different steaming times of Polygonatum polysaccharide.

Abstract
Since Curcumae Radix decoction pieces have multiple sources, it is difficult to distinguish depending on traditional cha-racters, and the mixed use of multi-source Curcumae Radix will affect its clinical efficacy. Heracles Neo ultra-fast gas phase electronic nose was used in this study to quickly identify and analyze the odor components of 40 batches of Curcumae Radix samples from Sichuan, Zhejiang, and Guangxi. Based on the odor fingerprints established for Curcumae Radix decoction pieces of multiple sources, the odor components was identified and analyzed, and the chromatographic peaks were processed and analyzed to establish a rapid identification method. Principal component analysis(PCA), discriminant factor analysis(DFA), and soft independent modeling cluster analysis(SIMCA) were constructed for verification. At the same time, one-way analysis of variance(ANOVA) combined with variable importance in projection(VIP) was employed to screen out the odor components with P<0.05 and VIP>1, and 13 odor components such as β-caryophyllene and limonene were hypothesized as the odor differential markers of Curcumae Radix decoction pieces of diffe-rent sources. The results showed that Heracles Neo ultra-fast gas phase electronic nose can well analyze the odor characteristics and rapidly and accurately discriminate Curcumae Radix decoction pieces of different sources. It can be applied to the quality control(e.g., online detection) in the production of Curcumae Radix decoction pieces. This study provides a new method and idea for the rapid identification and quality control of Curcumae Radix decoction pieces.

Abstract
This study employed orthogonal design and AHP-comprehensive scoring method to optimize the processing technology of wine-processed Polygonati Rhizoma, and then explored the immunomodulation performance of the product. Orthogonal test was established based on single factor test results to study the effects of soaking time, steaming time, and drying temperature on the quality of wine-processed Polygonati Rhizoma. Further, the analytic hierarchy process(AHP) and comprehensive scoring method were employed to determine the optimum processing parameters. The immunosuppression model of mice was established by injecting cyclophosphamide intraperitoneally. The body weight, immune organ index, and white blood cell count(WBC) and red blood cell count(RBC) in peripheral blood were compared between the mice administrated with the non-processed Polygonati Rhizoma and the wine-processed Polygonati Rhizoma prepared with modern and traditional methods. Further, the levels of interleukin-2(IL-2) and interferon-gamma(IFN-γ) in serum were determined by enzyme-linked immunosorbent assay(ELISA) for comparison. The processing parameters were optimized as follows: soaking in Chinese rice wine for 10 h, steaming for 20 h, and drying thick slices at 60 ℃. The wine-processed Polygonati Rhizoma prepared with both modern and traditional methods can significantly enhance the immune function, with similar performance. The optimized processing technology of wine-processed Polygonati Rhizoma is stable and feasible and the product prepared with this process has obvious immune-enhancing effect, which provides a basis for the quality standard formulation and the modern research of wine-processed Polygonati Rhizoma.

Abstract
Corni Fructus (CF), used for thousands of years in Asia as food and medicine, has different therapeutic effects before and after processing. In the past work, the quality assessment of Corni Fructus focused on the limited chemical compounds and rarely correlated external properties, such as color. The traditional sensory assessment relies partly on human eyes, which is quick but lacks objectivity. On a Shimadzu LC-20AD liquid chromatograph system equipped with a diode-array detector (DAD), we determined six major compounds (gallic acid, 5-hydroxymethyl-2-furaldehyde, morroniside, loganin, sweroside, and cornuside I). The extract was analyzed using ultra-high-performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (UHPLC-QTOF-MS) after the solid-phase extraction (SPE) step. Totally 58 compounds in raw and processed Corni Fructus were identified in negative and positive ion modes according to tandem mass spectrometry (MS/MS) fragments. Iridoids, carboxylic acids, tannins, flavonoids, triterpenes, fatty acids, saccharides, phospholipids, polysaccharide, amino acid, amide, furan, catechol, aldehyde, fatty alcohol and vitamin were included. A multivariate statistical analysis based on UHPLC-QTOF-MS filtered 17 differential compounds between raw and processed products. The CM-5 colorimeter was applied for digitizing surface and powder color. The contents of gallic acid, morroniside, loganin, cornuside I, and sweroside significantly correlated with color parameters in raw Corni Fructus, particularly adp* and bdp* , but not in processed products, according to Spearman correlation analysis. MS peak area of four compounds in raw products correlated significantly with color parameters Ldp* , adp* , bdp* , Lpd* , apd* , bpd* , respectively, while three compounds in processed products with Lpd* , apd* , bpd* . It revealed the relationship between compounds and color of Corni Fructus and the crucial compounds to color. In this study, we successfully developed a method for comprehensive quality evaluation of Corni Fructus that combines HPLC, UHPLC-QTOF-MS, and color determination.

Abstract
Based on UPLC characteristic chromatogram and quantitative analysis of multi-components by single marker(QAMS), the content of seven types of ginsenosides in Ginseng Radix et Rhizoma was simultaneously determined, and the quality of Ginseng Radix et Rhizoma was evaluated by the principal component analysis(PCA). The chromatographic separation was performed on the Acquity UPLC BEH C_(18) column(2.1 mm×100 mm, 1.7 μm) with the mobile phase of acetonitrile-water for gradient elution at the flow rate of 0.3 mL·min~(-1), the column temperature of 30 ℃, the detection wavelength of 203 nm, and the injection volume of 2 μL. The UPLC chromatogram was established with 19 batches of Ginseng Radix et Rhizoma samples from three producing areas by Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine(version 2012). Thirteen characteristic peaks were determined and seven components were identified. SPSS 26.0 was used to conduct PCA on the characteristic peak areas. With the peak of ginsenoside Rb_1 as reference peak S, ginsenoside Rb_1 showed good durability of relative correction factor as compared with other ginsenosides. The QAMS method for the determination of seven ginsenosides in Ginseng Radix et Rhizoma was established. There was no significant difference in results between the QAMS method and the external standard method. As revealed by the results of PCA and the determination of the total content of seven ginsenosides, the four batches of Ginseng Radix et Rhizoma numbered S19, S18, S1, and S2 were of superior quality. The characteristic chromatogram and QAMS method for the determination of seven ginsenosides in this study were convenient and accurate, which greatly shortened the analysis time and improved the analysis efficiency. The findings of this study are expected to provide a basis for the overall quality evaluation of Ginseng Radix et Rhizoma.

Abstract
Since the current identification method for Paeoniae Radix Alba is complex in operation and long time-consuming with high requirements for technicians, the present study employed Heracles NEO ultra-fast gas phase electronic nose(E-nose) technology to identify raw and sulfur-fumigated Paeoniae Radix Alba decoction pieces in order to establish a rapid identification method for sulfur-fumigated Paeoniae Radix Alba. The odors of raw Paeoniae Radix Alba and its sulfur-fumigated products were analyzed by Heracles NEO ultra-fast gas phase E-nose to obtain the odor chromatographic information. The chemometric model was established, and the data were processed by principal component analysis(PCA), discriminant function analysis(DFA), soft independent modeling of class analogy(SIMCA), and partial least squares discriminant analysis(PLS-DA). The differential compounds of raw and sulfur-fumigated samples were qualitatively analyzed based on the Kovats retention index and Arochembase. As revealed by the comparison of gas chromatograms of raw and sulfur-fumigated Paeoniae Radix Alba, the heights of several peaks in the chromatograms before and after sulfur fumigation changed significantly. The peak(No.8) produced by ethylbenzene disappeared completely due to sulfonation reaction in the process of sulfur fumigation, indicating that ethylbenzene may be the key component in the identification of Paeoniae Radix Alba and its sulfur-fumigated products. In PCA, DFA, SIMCA, and PLS-DA models, the two types of samples were separated into two different regions, indicating that the established models can clearly distinguish between raw and sulfur-fumigated Paeoniae Radix Alba. The results showed that Heracles NEO ultra-fast gas phase E-nose technology could realize the rapid identification of raw and sulfur-fumigated Paeoniae Radix Alba, which provides a new method and idea for the rapid identification of sulfur-fumigated Chinese medicine.

Abstract
Coronary heart disease(CHD) is a common cardiovascular disease in clinical practice. Curcumae Rhizoma(CR), an important herbal medicine for breaking blood stasis and resolving mass, is often used for the treatment of CHD caused by blood stasis syndrome. However, the anti-CHD components, targets, and mechanism are still unclear. Therefore, in this study, the chemical components of CR were separated and identified by ultra high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS). Based on the identified components, network pharmacology analysis, including target prediction and functional enrichment, was applied to screen out the main active components against CHD, and the potential mechanism was discussed. Finally, molecular docking was performed to verify the binding between the active components and the targets. The results showed that among the 52 chemical components identified in CR, 28 were related to CHD, involving 75 core targets. The core components included(4S)-4-hydroxy-gweicurculactone, curcumadione, and curcumenone, and the core targets included phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha(PIK3 CA), mitogen-activated protein kinase 1(MAPK1), and mitogen-activated protein kinase 3(MAPK3). In summary, through the active components, such as(4S)-4-hydroxy-gweicurculactone, curcumadione, and curcumenone, CR regulates the nerve repair, vasoconstriction, lipid metabolism, and inflammatory response, thereby exerts therapeutic effect on CHD.

Abstract
In this study, UPLC was used to establish the characteristic chromatograms of Curcumae Radix from different origins(LSYJ, WYJ, HSYJ, and GYJ) and the content determination method of 11 chemical components. The evaluation of characteristic chromatogram similarity, cluster analysis(CA), principal component analysis(PCA), and orthogonal partial least square discriminant analysis(OPLS-DA) were combined to evaluate the quality of Curcumae Radix from four origins. LSYJ, WYJ, HSYJ, and GYJ showed 15, 17, 15, and 10 characteristic peaks, respectively, and 8 of the peaks were identified. The characteristic chromatograms of Curcumae Radix samples(except for GYJ07) from the same origin showed the similarity greater than 0.854. The 11 chemical components had different content among the samples from four origins. Curcumenol, furanodienone, and isocurcumenol were rich in LSYJ; hydroxyisogermafurenolide, curdione, and furanodiene had high content in WYJ; gemacrone, β-elemene, bisdemethoxycurcumin, demethoxycurcumin, and curcumin were rich in HSYJ; all the components had low content in GYJ. The chemometric analysis showed that CA, PCA, and OPLS-DA could accurately classify the four origins of Curcumae Radix into four categories, and five different quality markers, namely furanodienone, curcumenol, curdione, hydroxyisogermafurenolide, and furanodiene, were screened out by OPLS-DA. UPLC in combination with multicomponent content determination is simple, rapid, reproducible, and specific, which can provide reference for the quality control and identification of Curcumae Radix from four origins.

Abstract
The methods for determining the characteristic chromatogram and index components content of Xuanfu Daizhe Decoction were established to provide a scientific basis for the quality evaluation of substance benchmarks and preparations. Eighteen batches of Xuanfu Daizhe Decoction were prepared with the decoction pieces of different batches and of the same batch were prepared respectively, and the HPLC characteristic chromatograms of these samples were established. The similarities of the chromatographic fingerprints were analyzed. With liquiritin, glycyrrhizic acid, 6-gingerol, ginsenoside Rg_1, and ginsenoside Re as index components, the high performance liquid chromatography was established for content determination with no more than 70%-130% of the mass average as the limit. The results showed that there were 19 characteristic peaks corresponding to the characteristic chromatograms of 18 batches of Xuanfu Daizhe Decoction, including 8 peaks representing liquiritin, 1,5-O-dicaffeoylqunic acid, ginsenoside Rg_1, ginsenoside Re, 1-O-acetyl britannilactone, ginsenoside Rb_1, glycyrrhizic acid, and 6-gingerol, and the fingerprint similarity was greater than 0.97. The contents of liquiritin, glycyrrhizic acid, 6-gingerol, and ginsenosides Rg_1 + Re in the prepared Xuanfu Daizhe Decoction samples were 0.53%-0.86%, 0.61%-1.2%, 0.023%-0.068%, and 0.33%-0.66%, respectively. Except for several batches, most batches of Xuanfu Daizhe Decoction showed stable contents of index components, with no discrete values. The characteristic chromatograms and index components content characterized the information of Inulae Flos, Ginseng Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, and Zingiberis Rhizoma Recens in Xuanfu Daizhe Decoction. This study provides a scientific basis for the further research on the key chemical properties of substance benchmark and preparations of Xuanfu Daizhe Decoction.

Abstract
This study aims to study the effective substance and mechanism of Ziziphi Spinosae Semen extract in the treatment of insomnia based on serum metabolomics and network pharmacology. The rat insomnia model induced by p-chlorophenylalanine(PCPA) was established. After oral administration of Ziziphi Spinosae Semen extract, the general morphological observation, pentobarbital sodium-induced sleep test, and histopathological evaluation were carried out. The potential biomarkers of the extract in the treatment of insomnia were screened by ultra-high performance liquid chromatography-mass spectrometry(UHPLC-MS) combined with multivariate analysis, and the related metabolic pathways were further analyzed. The "component-target-pathway" network was constructed by ultra-high performance liquid chromatography coupled with quadrupole-Exactive mass spectrometry(UHPLC-Q-Exactive-MS/MS) combined with network pharmacology to explore the effective substances and mechanism of Ziziphi Spinosae Semen in the treatment of insomnia. The results of pentobarbital sodium-induced sleep test and histopathological evaluation(hematoxylin and eosin staining) showed that Ziziphi Spinosae Semen extract had good theraputic effect on insomnia. A total of 21 endogenous biomarkers of Ziziphi Spinosae Semen extract in the treatment of insomnia were screened out by serum metabolomics, and the metabolic pathways of phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism, and nicotinate and nicotinamide metabolism were obtained. A total of 34 chemical constituents were identified by UHPLC-Q-Exactive-MS/MS, including 24 flavonoids, 2 triterpenoid saponins, 4 alkaloids, 2 triterpenoid acids, and 2 fatty acids. The network pharmacological analysis showed that Ziziphi Spinosae Semen mainly acted on target proteins such as dopamine D2 receptor(DRD2), 5-hydroxytryptamine receptor 1 A(HTR1 A), and alpha-2 A adrenergic receptor(ADRA2 A) in the treatment of insomnia. It was closely related to neuroactive ligand-receptor interaction, serotonergic synapse, and calcium signaling pathway. Magnoflorine, N-nornuciferine, caaverine, oleic acid, palmitic acid, coclaurine, betulinic acid, and ceanothic acid in Ziziphi Spinosae Semen may be potential effective compounds in the treatment of insomnia. This study revealed that Ziziphi Spinosae Semen extract treated insomnia through multiple metabolic pathways and the overall correction of metabolic disorder profile in a multi-component, multi-target, and multi-channel manner. Briefly, this study lays a foundation for further research on the mechanism of Ziziphi Spinosae Semen in treating insomnia and provides support for the development of innovative Chinese drugs for the treatment of insomnia.

Abstract
Derived from Curcuma plants, Curcumae Longae Rhizoma, Curcumae Rhizoma, Wenyujin Rhizoma Concisum, and Curcumae Radix are common blood-activating and stasis-resolving medicinals in clinical practice, which are mainly used to treat amenorrhea, dysmenorrhea, chest impediment and heart pain, and rheumatic arthralgia caused by blood stasis block. According to modern research, the typical components in medicinals derived from Curcuma plants, like curcumin, demethoxycurcumin, bisdemethoxycurcumin, curdione, germacrone, curcumol, and β-elemene, have the activities of hemorheology improvement, anti-platelet aggregation, anti-thrombosis, anti-inflammation, anti-tumor, and anti-fibrosis, thereby activating blood and resolving stasis. However, due to the difference in origin, medicinal part, processing, and other aspects, the efficacy and clinical application are different. The efficacy-related substances behind the difference have not yet been systematically studied. Thus, focusing on the efficacy-related substances, this study reviewed the background, efficacy and clinical application, efficacy-related substances, and "prediction-identification-verification" research method of blood-activating and stasis-resolving medicinals derived from Curcuma plants, which is expected to lay a theoretical basis for the future research on the "similarities and differences" of such medicinals based on integrated evidence chain and to guide the scientific and rational application of them in clinical practice.

Abstract
Processing of Chinese medicinals with vinegar is one of the characteristic processing techniques. Vinegar is vital for the quality of vinegar-processed decoction pieces. However, there have been no specified standards for adjuvants. Through consulting relevant literature and monographs, we comprehensively reviewed the historical evolution of processing with vinegar in records, selection and application of vinegar, and summarized the relevant standards and current status of vinegar as an adjuvant in China. According to the records in literature, vinegar is effective in activating blood, moving qi, dispersing blood stasis, removing toxin, promoting appetite, and nourishing the liver. Traditionally, rice vinegar is chosen in processing. Nowadays, the vinegar made from rice under solid-state fermentation should be chosen. At present, only food standards can be taken for reference for vinegar in the processing. Integrative and specific inspection indicators are lacking, so the standards for adjuvants need to be improved urgently. In addition, the inadequacy in quality control and management is also a major problem to be solved. Through literature research, we reviewed the historical evolution and research advance in vinegar to provide a reference for the standardization and further research of vinegar used in the Chinese medicinal processing.

Abstract
To evaluate the efficacy of rotation cross-advancement flap method in repairing the nasolabial deformity of complete unilateral cleft lip. A retrospective study was performed to analyze the children who were treated by using the rotating cross-advancement flap for repairing the complete unilateral cleft lip at the Fujian Medical University Union Hospital from October 2018 to July 2019. The clinical data such as patient's lip height, lip length, nostril height, nostril width, nostril area and so on were collected at the pre-operation, post-operation and following-up visits respectively and used to evaluate the efficacy of the treatment. Six children were included in the present study. The ratios of lip height on noncleft side to cleft side were 2∶1 at the pre-operation time. The ratios of nostril height on the noncleft side to the cleft side were about 2∶1. The ratios of the width and the area of the nostril were 1∶2 to 1∶3. At the post-operation time, the ratios of length and height of the lip at the cleft side to the noncleft side were around 1∶1. The shape of the nostrils and nasolabial fold were almost symmetrical between the cleft side and noncleft side. The shapes of the nasal sill were acceptable and the postoperative scars were not obvious. There were no obvious incision healing complications and the treatment effects were satisfactory. Rotation cross-advancement flap method was safe and reliable for repairing the nasolabial deformities in children with complete unilateral cleft lip.

Abstract
L~*, a~* and b~* values of prepared slices of Curcumae Rhizoma were measured by spectrophotometer. SPSS 21.0 was used for discriminant analysis to establish the color range and mathematical prediction model of prepared slices of Curcumae Rhizoma. The values of L~*, a~* and b~* of kwangsiensis ranged from 58.09-62.40, 4.53-5.66 and 23.61-24.29, while the values of L~*, a~* and b~* of phaeocaulis were between 64.02-70.71,-0.89-4.13 and 44.59-54.52, respectively. The values of L~*, a~* and b~* of wenyujin were 68.55-70.99,-0.11-1.47 and 28.26-32.19, respectively. The mathematical prediction model was proved to be able to realize 100% identification of Curcumae Rhizome of different origins through original and cross validation and external samples validation. A dual wavelength HPLC was established; the contents of 9 sesquiterpenoids and 3 Curcumae Rhizomes were determined simultaneously; and the contents of Curcumae Rhizome of different origins were determined. The results showed that kwangsiensis had higher contents of neocurdione, β-elemene and isocurcumaenol, phaeocaulis curcumin, furadienone, demethoxycurcumin and curcumin; and wenyujin mainly contained curdione, furadienes and guimarone. Pearson correlation analysis on L~*, a~*, b~* value and content of 12 components showed that curcumin, furadienone, demethoxycurcumin and curcumin had a significant positive correlation with b~* value(P<0.01). There was a significant negative correlation between neocurdione, β-elemene and isocurcumaenol and L~* value(P<0.01). Curdione, furadienes and guimarone were significantly correlated with L~* value(P<0.01),indicating that the appearance co-lor of Curcumae Rhizoma could reflect the change of the content of the internal components. This study provided reference for the rapid recognition of Curcumae Rhizoma and the establishment of quality evaluation system.

Abstract
As an outstanding representative of traditional Chinese medicine( TCM),ancient classical prescriptions carry the profound accumulation of the splendid civilization of Chinese medicine for thousands of years. It is the best part of the great treasure-house of Chinese medicine after thousands of years' training of TCM theory. It condenses the wisdom of all generations of doctors,and as the summary of clinical experience,it is the most brilliant pearl in the treasure house of TCM. The in-depth research and development of ancient classic prescriptions is a golden key to excavate the treasure house of TCM,which not only conforms to the development trend of TCM industry,but also brings unprecedented opportunities and challenges for the inheritance and innovation of contemporary Chinese herbal compound preparations. However,as a " new member" in the national drug research and development system,classic prescriptions have no specific implementation rules although the guidance is given by macro policies,and there is no successful case of research and development according to the registration requirements. Therefore,unified consensus and standards have not yet been formed for some key issues in the process of the development of the classic prescriptions,and much work is still in the exploration stage,so it is necessary to conduct in-depth research and discussion on these issues. In this paper,the problems in the research process of classical prescriptions were summarized,such as the resources of medicinal materials,the processing of decoction pieces,the prescription dosage,the molding technology and the quality evaluation,and the research strategy was put forward after analysis,hoping to provide a reference for the research and development of classical prescriptions.

Abstract
In order to determine the quality evaluation method for standard decoction of Coptidis Rhizoma,15 batches of standard decoction of Coptidis Rhizoma were prepared by using standardized process. Parameters such as traits,p H value,indicative component content,fingerprint similarity,composition transfer rate and dry extract rate were selected as the indexes for quality evaluation. Similarity evaluation and cluster analysis were performed for HPLC fingerprint of standard decoction,and mathematical model was used to study the correlation between dry extract rate,berberine content,berberine transfer rate in standard decoction and berberine content in decoction pieces. The results showed that the similarity of fingerprints was greater than 0. 99 for these 15 batches of standard decoctions of Coptidis Rhizoma. In cluster analysis,the standard decoctions of Coptidis Rhizoma from 4 producing areas were classified into 3 categories,consistent with the content determination results,indicating that there were quality differences among different producing areas.R2 in three linear regression mathematical models established was all greater than 0. 9,with significant difference. The validation of three batches of data showed that the models had good accuracy. Therefore,this model can be used to predict the quality of standard decoction prepared from different Coptidis Rhizoma pieces. In the standard decoction process established in this study,the integrity of the traditional process was greatly preserved,and the established quality evaluation method could be used to comprehensively examine the quality of the standard decoction,which can provide a demonstration for the related research of water extraction preparation containing Coptidis Rhizoma pieces.

Abstract
To optimize the technology of Gardeniae Fructus processed with ginger juice,establish fingerprints and simultaneously determine seven compounds( geniposidic acid,chlorogenic acid,genipin-1-β-D-gentiobioside,geniposide,rutin,crocin Ⅰ,and crocin Ⅱ) by using ultra high performance liquid chromatography( UPLC). Waters ACQUITY UPLC BEH C18( 2. 1 mm×50 mm,1. 7μm) column was used with acetonitrile and 0. 1% formic acid solution as mobile phase for gradient elution at the flow rate of 0. 4 m L·min-1. The data was comprehensively processed and analyzed with similarity evaluation,principal component analysis( PCA) and partial least squares discriminant analysis( PLS-DA) methods. Twenty common peaks were identified in this study,and the similarity of samples was over 0. 97. The results of PCA and PLS-DA showed that there were differences in chemical compositions and contents between the raw Gardeniae Fructus and those processed with ginger juice,with 9 potential differentiated chromatographic peaks. After being processed with ginger juice,the contents of chlorogenic acid,crocin Ⅰ and crocin Ⅱ were less than before and the contents of other four compositions were higher than before. The optimized preparation for Gardeniae Fructus processed with ginger juice was stable and feasible. The methods of UPLC fingerprints and simultaneous determination of seven components can be effectively carried out to distinguish Gardeniae Fructus and Gardeniae Fructus processed with ginger juice.

Abstract
Totally 21 batches of Gastrodiae Rhizoma pieces from various habitats with different appearance characteristics were analyzed. Five active components( gastrodin,4-hydroxybenzyl alcohol,parishin B,parishin C,and parishin A) were determined by UPLC. Polysaccharide content was determined by phenol sulfuric acid method. And the content of alcohol extracts was determined. The correlation between appearance characteristics and active components,polysaccharide content and amount of alcohol extracts of Gastrodiae Rhizoma pieces was statistically analyzed by SPSS 19. 0 software. And the five active components in the 21 Gastrodiae Rhizoma pieces were clustered by using the Ward' s method in SPSS 19. 0 software. The study found that inconspicuous keratinous Gastrodiae Rhizoma had a low content of each component,and the degree of keratin was positively correlated with the content of each component and the extract,with no significant correlation with the polysaccharide content. In the cluster analysis,the 21 batches were divided into three groups,except the second group whose gastrodin content was significantly higher than the special conditions of other groups. According to the content of the five active components,19 batches of Gastrodiae Rhizoma pieces were classified into two groups with obvious keratin and no obvious keratin. In terms of color,with the deepening of brown color,the content of each component showed a downward trend. The grading of decoction pieces of Gastrodiae Rhizoma shall give full consideration to the color and texture. And the combination of chemical composition and appearance characteristics is an indicator to evaluate the product specification standards.

Abstract
Ten batches of Angelica sinensis from three producing areas( Tuoxiang,Minxian and Weiyuan of Gansu province) were selected as the research objects,and processed into raw A. sinensis,A. sinensis with alcohol,and A. sinensis with soil respectively through the standard processing methods. Ultra-high performance liquid chromatography( UPLC) was used to establish fingerprint for three processed products of A. sinensis,and determine the contents of 9 phenolic acids and phthalide compounds. The similarity was analyzed with Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine,which showed that the chromatographic peaks of the same processed samples of A. sinensis were basically similar,with all similarities greater than 0. 950. The difference between different processed products and their control spectra was not obvious,with all similarities also higher than 0. 950.On the basis of using principal component analysis( PCA) and OPLS-DA to seek the difference components between groups,the improved distance coefficient method can be used to effectively distinguish the three processed products of A. sinensis by fingerprint similarity. At the same time,the determination method of nine phenolic acids and phthalide in A. sinensis was established by UPLC,and the comparison between different processed products was carried out. The results showed that the content of various components was changed as compared with the raw A. sinensis. The contents of coniferyl ferulate and ligustilide in the A. sinensis with alcohol were increased significantly,and the content of coniferyl ferulate was obviously increased in A. sinensis with soil. The method established in this paper can effectively distinguish different processed products of A. sinensis and determine the content of the main components in them.

Abstract
To compare the effects of Curcumae Rhizoma/vinegar-processed Curcumae Rhizomaon immune hepatic fibrosis, proliferation of HSC-T6, and expressions of α-SMA and Procollagen I. The immunological liver fibrosis model was prepared through intraperitoneal injection with porcine serum 0.5 mL in each rat, twice a week, for 14 weeks. Expressions of serum ALT, AST, PC-Ⅲ, IV-C, LN, HA and HYP, MDA in liver tissues were observed after administration of Curcumae Rhizoma/vinegar-processed Curcumae Rhizoma (0.95, 1.90 g•kg⁻¹). The pathological changes in liver tissues were observed by HE staining. Masson staining and Sirius red staining were used to observe the expression of collagen in rat liver. HSC-T6 was cultured, and the proliferation of HSC-T6 was determined by MTT assay at different concentrations in 12, 24, 36, 48 h. The expressions of α-SMA and Procollagen I were detected by Real-time PCR. The results showed that expressions of serum ALT, AST, PC-Ⅲ, IV-C, LN and HA in Curcumae Rhizoma/vinegar-processed Curcumae Rhizoma groups (0.95, 1.90 g•kg⁻¹) were significantly lower than model group; in terms of effect, vinegar-processed Curcumae Rhizoma group was superior to Curcumae Rhizoma group. Curcumae Rhizoma/vinegar-processed Curcumae Rhizoma containing serum could inhibit the proliferation of HSC-T6 in a dose-effect and time-effect manner. Expressions of α-SMA and Procollagen I in HSC-T6 were decreased after 24 h, especially in 20% vinegar-processed Curcumae Rhizoma containing serum group (P<0.01). Both Curcumae Rhizoma/vinegar-processed Curcumae Rhizoma could reduce immune hepatic fibrosis to varying extent. Their anti-hepatic fibrosis mechanism may be correlated with inhibition of the proliferation of HSC-T6, and reduction of the formation of extracellular matrix and promotion of its degradation.

Abstract
Volatile oils are important active components in traditional Chinese medicine, but their components are complicated and unstable. It is common to use cyclodextrin inclusion technique to improve the stability of volatile oils and make them easier to be prepared. At present, β-cyclodextrin (β-CD) is the most common inclusion material. The evaluation indicators for inclusion technique usually contain the inclusion rate and the oil content in the inclusion compound. However, the articles about the study on selecting inclusion materials for volatile oils were few. In this paper, menthol, the main active ingredient of mint volatile oil, was used as model drug, while β-CD and hydroxypropyl-β-cyclodextrin (HP-β-CD) were used as the inclusion materials. Inclusion equilibrium constant (K), solubilization ratio were investigated, and the results were combined with IR, DSC and TG to verify the formation of inclusion complexes. It turned out that in the range of 0-15 mmol•L⁻¹, the solubility of menthol was increased linearly with the increase of HP-β-CD concentration, with AL-type phase solubility diagram, K=3 188.62 L•mol⁻¹; in the range of 0-12.5 mmol•L⁻¹, the solubility of menthol was increased linearly with the increase of β-CD concentration, K=818.73 L•mol⁻¹. When the concentration was over 12.5 mmol•L⁻¹, the solubility of menthol appeared to be a negative deviation with the increase of β-CD concentration, with AN-type solubility diagram. The above results showed that the inclusion behavior was different between β-CD and HP-β-CD, laying a foundation for further study on inclusion complexes of volatile oil.

Abstract
To explore the effect of vinegar-processed Curcumae Rhizoma on endogenous metabolites in bile by investigating the endogenous metabolites difference in bile before and after Curcumae Rhizoma was processed with vinegar. Alcohol extracts of crude and vinegar-processed Curcumae Rhizoma, as well as normal saline were prepared respectively, which were then given to the rats by intragastric administration for 0.5 h. Then common bile duct intubation drainage was conducted to collect 12 h bile of the rats. UPLC-TOF-MS analysis of bile samples was applied after 1∶3 acetonitrile protein precipitation; unidimensional statistics were combined with multivariate statistics and PeakView software was compared with network database to identify the potential biomarkers. Vinegar-processed Curcumae Rhizoma extracts had significant effects on metabolites spectrum in bile of the rats. With the boundaries of P<0.05, 13 metabolites with significant differences were found in bile of crude and vinegar-processed Curcumae Rhizoma groups, and 8 of them were identified when considering the network database. T-test unidimensional statistical analysis was applied between administration groups and blank group to obtain 7 metabolites with significant differences and identify them as potential biomarkers. 6 of the potential biomarkers were up-regulated in vinegar-processed group, which were related to the metabolism regulation of phospholipid metabolism, fat metabolism, bile acid metabolism, and N-acylethanolamine hydrolysis reaction balance, indicating the mechanism of vinegar-processed Curcumae Rhizoma on endogenous metabolites in bile of the rats.

Abstract
OBJECTIVE To study the effect of ligustrazine nanoparticles nano spray (LNNS) on transforming growth factor β (TGF-β)/Smad signal protein of rat peritoneal mesothelial cells (RPMC) induced by tumor necrosis factor α (TNF-α), and the anti-adhesion mechanism of LNNS in the abdominal cavity. METHODS The primary culture and subculture of rat peritoneal mesothelial cells (RPMC) was processed by trypsin digestion method in vitro. The third generation was identifified for experiment and divided into 5 groups: a blank group: RPMC without treatment; a control group: RPMC stimulated with TNF-α; RPMC treated by a low-dosage LNNS group (2.5 mg/L); RPMC treated by a medium-dosage LNNS group (5 mg/L); and RPMC treated by a high-dosage LNNS group (10 mg/L). Reverse transcription-polymerase chain reaction was applied to test the expression of fifibronectin, collagen I (COL-I), TGF-β mRNA, and Western blot method to test the Smad protein 7 expression of RPMC. RESULTS Compared with the blank group, a signifificant elevation in fifibronectin (FN), COL-I and TGF-β mRNA expression of RPMC were observed in the control group (P<0.05). Compared with the control group, LNNS suppressed the expressions of FN, COL-I and TGF-β mRNA in a concentrationdependent manner (P<0.05). The expression of Smad7 protein of RPMC was down-regulated by TNF-α stimulation, and up-regulated with the increase of LNNS dose (P<0.05). CONCLUSIONS TNF-α may induce changes in RPMC's viability, leading to peritoneal injury. LNNS could reverse the induction of fifibrosis related cytokine FN, COL-I and TGF-β, up-regulating the expression of Smad7 by TNF-α in RPMC, thus attenuate peritoneal injury by repairing mesothelial cells.

Abstract
Infestation, moldy and other phenomenon in the processing and storage of Chinese herbal medicines is a problem that faced in the production of Chinese traditional medicine. The low productivity of traditional processing methods can not guarantee the quality of Chinese herbal medicines. Sulfur fumigation is the first choice of grassroots to process the Chinese herbal medicine with its low cost and easy operation. Sulfur fumigation can solve some problems in the processing and storage of Chinese herbal medicines, but modern pharmacological studies show that long-term use of Chinese traditional medicine which is fumigated by sulfur can cause some serious harm to human liver, kidney and other organs. This paper conducts a review about the application history of sulfur fumigation, its influence to the quality of Chinese herbal medicines as well as domestic and foreign limits to sulfur quantity, and a brief introduction of the status of modern processing technologies in the processing of food and some Chinese herbal medicines, the problems ex- isting in the Chinese herbal medicines processing, which can provide a reference basis for the further research, development and application of investigating alternative technologies of sulfur fumigation.

Abstract
The contents of adenosine, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxybenzaldehyde, parishin and sulfur dioxide residue were compared in differently-processed Gastrodiae Rhizoma to provide the basis for a reasonable processing method of Gastrodiae Rhizoma. The analysis was performed on a Merck Purospher STAR column (4.6 mm x 250 mm, 5 μm) with a mobile phase consisting of methanol and water (containing 0.1% formic acid) under gradient elution at a flow rate of 1.0 mL x min(-1). The eluates were detected at 270 nm, and the column temperature was 35°C. The content of adenosin, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxy-benzaldehyde and parishin in processing of boiling or sulfur-fumigated were lower than that of in processing of steaming. Furthermore, the sulfur dioxide residue of sulphur-fumigated groups exceed 400 mg x kg(-1). This stable and reliable method will contribute to the quality control of different processed Gastrodiae Rhizoma.

Abstract
To compare the differences of the active ingredient contents and the sulfur dioxide residue in Astragali Radix before and after sulfur fumigation and provide a basis for establishing an alternative processing method. Astragali Radix, harvested at the same time in Longxi Gansu, were processed with different methods. high performance liquid chromatography (HPLC) was used to determine the contents of the active ingredients in Astragali Radix and the revised method of the pharmacopoeia of China in 2011 was applied to determine the sulfur dioxide residue. The results show that the three-fold sulfur-fumigation group has the highest level of astragaloside IV and the dried sulfur-fumigation group with 10% water has the lowest level; the content of calycosin-7-O-β-D-glucoside is the highest in naturally dried group and the lowest in the group of sulfur fumigating for 3 times; the sulfur dioxide residue of all sulfur-fumigation groups exceeds certain limit significantly and the group of sulfur fumigating for 3 times reaches the highest level.

Abstract
Sulfur fumigation, which is traditional method for preservation, pest control, insecticide and sterilization, has long been widely used in processing and storage and played a positive role of traditional Chinese medicine (TCM). As some businesses sided pursuit of profit, abused and repeated use of sulfur fumigation, have resulted in a large number of harmful residues, such as sulf dioxide (SO2) and harmful heavy metals, which brings a significant impact and danger on human health. This article summarizes the sulfur species and the sulfur fumigation methods and analyzes the harmful substances in TCM after sulfur fumigation, to provide a reference of the choice of species for the sulfur, the optimization of sulfur fumigation process and the standardized processing of TCM after sulfur fumigation.

Abstract
BACKGROUND Recently, the combination of acupuncture and Chinese medicine as a practical strategy to treat diseases is receiving considerable attention worldwide as they are usually found to exhibit intriguing therapeutic effectiveness. The current study aimed to study the adjunct effect of acupuncture on target tissue distribution of schisandra lignans when acupuncture is combined with Schisandra chinensis. METHODS A simple and reliable high performance liquid chromatography-electrospray tandem-mass spectrometry (HPLC-ESI-MS) method for simultaneous analysis of three bioactive lignans (schisandrin, deoxyschisandrin and schisandrin B) in rat tissues was established. Using this analytical method we evaluated whether acupuncture had a synergistic effect on the tissue distribution of schisandra lignans. RESULTS Tissue concentrations of the three lignans in the group receiving acupuncture were significantly higher than those in the schisandra only group, suggesting that acupuncture may potently increase tissue concentrations of schisandra lignans. The highest concentrations of the three lignans occurred in the liver compared with other tissues, and tissue concentrations in the heart, spleen, lungs and kidneys were increased by 315%, 203%, 250% and 224%, respectively. In addition, retention times of the lignans in tissues were prolonged for a relative long time. CONCLUSIONS Our date indicate that the combined use of acupuncture and Schisandra chinensis could produce a synergistic effect which could play a beneficial role on promoting the tissue distribution of lignans. This has supported our initial hypothesis. The HPLC-MS method showed good sensitivity in quantifying the three schisandra lignans in different tissues.

Abstract
The essay summarizes the current development and application of reference extracts from traditional Chinese medicines (TCMs). Through the analysis on problems in the quality control of TCMs, and on the basis of the current application of reference extracts in Chinese Pharmacopoeia, it investigates reference extracts from TCMs and forecasts the study orientation on TCM quality standards. Despite a wide prospect for the application of reference extracts in quality control of TCMs, there remain problems in varieties and standards. It is of great significance for the TCM understanding to further promote the development of reference extracts.

Abstract
OBJECTIVE To study the effect of phospholipids composition on pharmaceutical characteristics of liposomes containing zedoary turmeric oil (ZTO). METHODS The ZTO was extracted supersonically by solvent and then colored by sulfuric acid-vanillin reagent. The ZTO liposomes were prepared by ethanol injection method. To determine the entrapment efficiency of the ZTO liposomes, we passed the liposome suspension through a Sephadex G-50 column equilibrated with PBS. Pharmaceutical characteristics of different liposomes such as size, zata potential, entrapment efficiency, stablility were determined and compared. RESULTS The ZTO liposomes and free drug could be separated completely by the Sephadex G-50 chromatography, and the column recovery was (100.09+/-3.375)% (n=5). The ZTO liposomes composed of hydrogenated soybean phosphatidylcholine (HSPC) possessed the worst entrapment efficiency and sedimentation stability. The entrapment efficiency of the ZTO liposomes composed of soybean phosphatidylcholine (SPC) was equal to that of liposomes composed of both HSPC and SPC. However, The sedimentation and leakage stabilities of the latter were significantly higher than those of SPC liposomes. CONCLUSION As the carrier of the ZTO liposomes, the composition of both HSPC and SPC can improve its stability.
