Abstract
Inspired by the interpretation of two-dimensional (2D) nuclear magnetic resonance spectra, an efficient strategy was proposed for pinpointing bioactive components from complex natural products. An off-line comprehensive countercurrent chromatography (CCC) × high-performance liquid chromatography (HPLC) was employed to achieve a 2D chemical chromatogram, and 2D bioassay profilings were obtained from bioassays of the eluent of the first dimension (1D) CCC and the eluent of the second dimension (2D) HPLC. Then 2D chemical chromatograms and 2D bioassay profilings were matched for pinpointing bioactive natural components from complex matrices. Thus, bioactive components in a complex matrix could be efficiently analyzed, separated, and bioactivity-determined. This experimental scheme was successfully demonstrated with a traditional medicinal herb Polygonum cuspidatum Sieb. et Zucc. The feasibility of this 2D strategy was verified with tyrosinase inhibition assay, α-glucosidase inhibition assay, DPPH radical scavenging assay, and ABTS•+ decolorization assay. Eight natural inhibitors were successfully pinpointed and identified from P. cuspidatum. Both pieceid-2″-O-gallate (10) and vanicoside B (20) were screened and identified as natural tyrosinase inhibitors for the first time. Meanwhile, vanicoside B (20) was also found as the strongest α-glucosidase inhibitor among all the isolated components. Most of the compounds exhibited much higher radical scavenging activities. Compared with traditional methodology based on one-dimensional chromatographic separation, the present 2D strategy would be more precise, efficient, and convenient to screen and separate bioactive compounds from complex matrices.

The Pharmacological Effects and Pharmacokinetics of Active Compounds of Artemisia capillaris. Biomedicines 2021; 9:biomedicines9101412. [PMID: 34680529 PMCID: PMC8533588 DOI: 10.3390/biomedicines9101412] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 09/22/2021] [Accepted: 09/28/2021] [Indexed: 12/18/2022] Open
Abstract
Artemisia capillaris Thunb. (A.capillaris, Yin-Chen in Chinese) is a traditional medicinal herb with a wide spectrum of pharmacological properties ranging from effects against liver dysfunction to treatments of severe cirrhosis and cancer. We used relevant keywords to search electronic databases, including PubMed, Medline, and Google Scholar, for scientific contributions related to this medicinal herb and the pharmacokinetics of its components. The pharmaceutical effects of A.capillaris contribute to the treatment not only of viral hepatitis, cirrhosis, and hepatocellular hepatoma, but also metabolic syndrome, psoriasis, and enterovirus in the clinic. The bioactive compounds, including scoparone, capillarisin, scopoletin, and chlorogenic acid, exhibit antioxidant, anti-inflammatory, antisteatotic, antiviral, and antitumor properties, reflecting the pharmacological effects of A.capillaris. The pharmacokinetics of the main bioactive compounds in A. capillaris can achieve a maximum concentration within 1 hour, but only chlorogenic acid has a relatively long half-life. Regarding the use of the A. capillaris herb by health professionals to treat various diseases, the dosing schedule of this herb should be carefully considered to maximize therapeutic outcomes while lessening possible side effects.

Abstract
Natural products are very attractive for development of medicine. Their structure and bioactivities are often beyond human knowledge and imagination. We have developed isolation methods for target protein-oriented natural products so as quickly to discover bioactive compounds from natural resources. This review summarizes our recent results including protein beads methods for neural stem cells differentiation activators and new cancer drug candidates. Syntheses of isolated compounds are described. We also developed protein plate method for identification of protein-protein interaction inhibitors. Because protein binding ability is tightly related to bioactivity, protein-based natural products isolation is a powerful means to find new candidate medicines.

Abstract
As the first and key step of traditional Chinese medicine (TCM)-guided drug development, lead discovery necessitates continuous exploration of new methodology for screening bioactive compounds from TCM. This work intends to establish a strategy for rapidly recognizing β2-adrenergic receptor (β2-AR) target compounds from the fruit of Siraitia grosvenorii (LHG). The method involved immobilization of β2-AR onto amino-microsphere to synthesize the receptor column, the combination of the column to high-performance liquid chromatography (HPLC) to screen bioactive compounds of LHG, the identification of the compounds by HPLC coupled with mass spectrometry (MS), and the evaluation of druggability through pharmacokinetic examination by HPLC-MS/MS. Mogroside V was screened and identified as the β2-AR-targeted bioactive compounds in LHG. This compound exhibited desired pharmacokinetic behavior including the time to reach peak plasma concentrations of 45 min, the relatively low elimination of 138.5 min, and the high bioavailability. These parameters indicated that mogroside V has a good druggability for the development of new drugs fighting β2-AR-mediated respiratory ailments like asthma. The combination of the methods in this work is probably becoming a powerful strategy for screening and early evaluating the bioactive compounds specifically binding to G-protein-coupled receptor target from complex matrices including TCM.

Abstract
Hes1 dimer inhibitor, agalloside (2), which can accelerate the differentiation of neural stem cells was isolated by using Hes1-immobilized beads.
The Hes1 dimer inhibitor, agalloside (2), which can accelerate the differentiation of neural stem cells is described. Six natural products, including one new natural product, which bind to Hes1 were rapidly isolated by a developed “target protein oriented natural products isolation” (TPO-NAPI) method using Hes1-immobilized beads. Of the six compounds, 2 inhibited Hes1 dimer formation at both the protein- and cellular level. Neural stem cells treated with 2 differentiated to neurons with longer neurites than cells treated with varproic acid or retinoic acid. Moreover, 2 exhibited specificity for neurons. This promotion of differentiation was supported by an increase in the mRNA expression of the proneural genes, Mash1 and Ngn2, which were inhibited by Hes1.

Abstract
In this review, we report a new reverse approach (from finding bioactive molecules to separating target compounds in the related plant) by using virtual screening, immobilized enzyme and polyclonal antibody, molecularly imprinted polymers for finding, and separating the active compounds from TCM. This approach is faster and more efficient than the traditional time-consuming approach (from selecting the plant to separating compounds following the bioassay guidance).:

Abstract
Two stable high-performance liquid chromatography (HPLC) methods were developed that could quantitatively analyze 10 major marker compounds of Artemisia capillaris Thunb and could also distinguish among 'Injinho' and 'Myeon-injin' and 'Haninjin'--A. capillaris collected in autumn, A. capillaris collected in spring and A. iwayomogi, which can be misused as 'Injinho' in Korean herbal drug markets. The first HPLC method was a reversed-phase chromatography using a C18 column with an isocratic solvent system of phosphoric acid (0.05%) and acetonitrile at the flow rate of 1.0 mL/min, ultraviolet (UV) detection wavelength at 254 nm and column temperature at 40°C. Calibration and quantitation were made by using acetaminophen as an internal standard (I.S-A) and chlorogenic acid (1) was determined within 20 min. The second HPLC method was a reversed-phase chromatography using a C18 column with a gradient solvent system of phosphate buffer (0.015 M, pH 6) and acetonitrile at the flow rate of 1.0 mL/min, UV detection wavelength at 254 nm and column temperature at 40°C. Calibration and quantitation were made by using ethylparaben as an internal standard (I.S-B) and 3,5-di-O-caffeoylquinic acid (2), 3,4-di-O-caffeoylquinic acid (3), 4,5-di-O-caffeoylquinic acid (4), hyperoside (5), isoquercitrin (6), isorhamnetin 3-O-robinobioside (7), isorhamnetin-3-O-galactoside (8), isorhamnetin-3-O-glucoside (9) and scoparone (10) were determined within 60 min. Pattern recognition analysis of data from the 60 samples classified them clearly into three groups. These assay methods could be applied for QA/QC of A. capillaris and Artemisia iwayomogi.

Abstract
The review, as can be deduced from the title, focuses on both theoretical and practical aspects of the use of mass spectrometry as a third, added dimension to a comprehensive LC (LC × LC) system, generating the most powerful analytical tool today for non-volatile analytes. The first part deals with the technical requirements for linkage of an LC × LC system to an MS one, including the choice of the mobile phase (buffer and salts), flow rate (splitting), type of ionization (interface); advantages and disadvantages of off-line and on-line methods are discussed, as well. A discussion of the various aspects of instrumentation is provided, both from a chromatographic and mass spectrometry standpoint, with particular emphasis directed to the choice of column sets, spatial resolution, mass resolving power, mass accuracy, and tandem-MS capabilities. The extent to which mass spectrometry may be of aid in unraveling column-outlet multicompound bands is highlighted, along with its effectiveness as a chromatographic detector of excellent sensitivity, universality yet with potential in terms of selectivity and amenability to quantitative analysis over a wide dynamic range. The following section of the review contains significant applications of comprehensive two-dimensional LC coupled to MS in different areas of research, with details on interfaces, column stationary phases, modulation and MS parameters. It is not the intention of the authors to provide a comprehensive description of the techniques, but merely to discuss only those aspects which are essential for successful applications of the LC-MS combination. The reader will be acquainted with the enormous potential of this hyphenated technique, and the factors and instrumental developments that have concurred to make it emerge to a central role in specialized fields, such as proteomics.

Abstract
It is known that the choice of solvent system for high speed counter-current chromatography separation is of utmost importance. In this study, a simple and rapid thin layer chromatograph coupling with fluorometric (TLC-F) method has been used to determine the partition coefficient of target compounds in HSCCC solvent system. Two components, 6,7-dimethoxycoumarin and 5-hydroxymethyl-2-furfural were successfully separated from purple sweet potato extracts by successive sample injection for the first time, using n-hexane-ethyl acetate-methanol-water (1:2:1:1, v/v/v/v) as the solvent system. Additionally, statistical analysis showed that there was no significant difference in partition coefficient obtained by the TLC-F method and by HPLC, which demonstrated the usefulness of TLC-F method.

Abstract
INTRODUCTION Mailuoning is prepared from a traditional formula of Chinese medicines and widely used as an antithrombotic agent. In this study, the platelet binding assay was used as a novel biospecific separation and analysis method to explore its active constituents, which could be considered as marker compounds for quality control. OBJECTIVE To establish a rapid and simple method to predict marker compounds in herbal medicine injection and evaluate the effects of those compounds. MATERIAL AND METHODS Platelets were used to bind and separate constituents. Binding constituents were analysed and taken as potential active compounds for further evaluation. Solid-phase-extraction was adopted to improve sensitivity. HPLC-DAD and ESI-MS were used to determine the binding constituents. RESULTS Five compounds were extracted through the platelet binding process and identified as neochlorogenic acid, caffeic acid, isochlorogenic acid and their isomers. Caffeic acid was selected for the flow cytometric assay to test its effect on platelets activation, which was determined by CD62P (P-selectin) expression. The results indicated that caffeic acid could significantly inhibit platelet activation while chlorogenic acid did not. CONCLUSION Caffeic acid could be considered as a marker compound of Mailuoning injection due to its anti-platelet effect. The study also suggested that platelet binding assay combined with some preconcentration technique could be efficiently used to predict anti-platelet compounds in complicated herbal medicines.

Abstract
Recent researches shows that amino acids (AA) are not only cell signaling molecules but are also regulators of gene expression and the protein phosphorylation cascade. More precise analysis of AA composition is reckoned to be one of the most important applications in the biomedical and pharmaceutical fields. In this paper, we develop a sample, sensitive and mild method using 2-[2-(7H-dibenzo[a,g]carbazol-7-yl)-ethoxy]ethyl chloroformate (DBCEC) as A labeling reagent for AA determination by high-performance liquid chromatography (HPLC) with fluorescence detection (FLD) and identification with mass spectroscopy. The maximum excitation and emission wavelengths for DBCEC-AA derivatives were 300 and 395 nm, respectively. This method, in conjunction with a gradient elution, offered a baseline resolution of 20 AA on a reversed-phase Hypersil BDS C(18) column. LC separation for the derivatized AA showed good reproducibility, and all AA were found to give excellent linear responses with correlation coefficients > 0.9993. The calculated detection limits with a 25.0 fmol injection of each AA (at a signal-to-noise ratio of 3:1) ranged from 2.62 to 22.6 fmol. This method was applied to determine the AA composition in Saussurea involucrate and Artemisia capillaris Thunb. Meanwhile, this method exhibits a powerful potential for trace analysis of AA from biomedicine, foodstuff and other complex samples.

Abstract
To target complex, multi-factorial diseases more effectively, there has been an emerging trend of multi-target drug development based on network biology, as well as an increasing interest in traditional Chinese medicine (TCM) that applies a more holistic treatment to diseases. Thousands of years' clinic practices in TCM have accumulated a considerable number of formulae that exhibit reliable in vivo efficacy and safety. However, the molecular mechanisms responsible for their therapeutic effectiveness are still unclear. The development of network-based systems biology has provided considerable support for the understanding of the holistic, complementary and synergic essence of TCM in the context of molecular networks. This review introduces available sources and methods that could be utilized for the network-based study of TCM pharmacology, proposes a workflow for network-based TCM pharmacology study, and presents two case studies on applying these sources and methods to understand the mode of action of TCM recipes.

Abstract
Traditional Chinese medicines (TCMs) are getting more and more popular nowadays in the whole world for improving health condition of human beings as well as preventing and healing diseases. TCM is a multi-component system with components mostly unknown, and only a few compounds are responsible for the pharmaceutical and/or toxic effects. The large numbers of other components in the TCM make the screening and analysis of the bioactive components extremely difficult. So, separation and analysis of the desired chemical components in TCM are very important subjects for modernization research of TCM. Thus, many novel separation techniques with significant advantages over conventional methods were introduced and applied to separation and analysis of the chemical constituents in TCM. This review presents just a brief outline of the applications of different separation methods for the isolation and analysis of TCM constituents.

Abstract
The aim of this study was to screen for the anti-inflammatory activity of fractions and compounds from Atractylodes macrocephala Koidz. The rhizomes of Atractylodes macrocephala were treated with supercritical CO(2) fluid and the extract was separated by normal-phase and reverse-phase column chromatography. The separated samples were screened with white blood cell membrane (WBCM) chromatography (WBCM-C). The anti-inflammatory effects of these fractions and components were tested pharmacologically in vivo. The results indicated that the retention characteristics of the petrol-ether (1:1, v/v) fraction (BZC-2) of the supercritical CO(2) extract, the atractylenolide I and 14-acetoxy-12-senecioyloxytetradeca-2E,8E,10E-trien-4, 6-diyn-1-ol isolated from BZC-2 as active fractions and components were similar to that of dexamethasone in WBCM-C. Therefore, they may act on WBCM and its receptors. BZC-2 has shown anti-inflammatory effects in acute and chronic inflammation models in rats and mice. Oral administration of atractylenolide I and 14-acetoxy-12-senecioyloxytetradeca-2E,8E,10E-trien-4,6-diyn-1-ol produced significant anti-inflammatory effects in acute and chronic inflammation models in mice. The screening results with WBCM-C were correlated significantly with pharmacological effects in vivo. Atractylenolide I and 14-acetoxy-12-senecioyloxytetradeca-2E,8E,10E-trien-4,6-diyn-1-ol were the main components of Atractylodes macrocephala that were effective as anti-inflammatory agents.

Abstract
In this work, for the first time, microwave distillation (MD) coupled with simultaneous headspace single-drop microextraction (HS-SDME) was developed for the determination of the volatile components in the Chinese herb, Artemisia capillaris Thunb. The volatile components were rapidly isolated by MD, and simultaneously extracted and concentrated by using a dodecane microdrop. The volatile oil extracted in the microdrop solvent was analyzed by gas chromatography-mass spectrometry (GC-MS). The experimental parameters of solvent selection, microdrop volume, microwave power, irradiation time and sample amount were investigated, and the method precision was also studied. The optimal parameters were extraction solvent of dodecane, solvent volume of 2.0 microL, microwave power of 400 W, irradiation time of 4 min, and sample amount of 2.0 g. Thirty-five volatile compounds present in Artemisia capillaris Thunb. were identified by using the proposed method, which were identical with those obtained by the conventional steam distillation method. The experimental results showed that MD-HS-SDME is a simple, rapid, reliable, and solvent-free technique for the determination of volatile compounds in Chinese herbs.

Abstract
The most basic task in proteomics remains the detection and identification of proteins from a biological sample, and the most traditional way to achieve this goal consists in protein separations performed by two-dimensional polyacrylamide gel electrophoresis (2-D PAGE). Yet the 2-D PAGE-mass spectrometry (MS) approach has its drawbacks with regard to automation, sensitivity, and throughput. Consequently, considerable effort has been devoted to the development of non-gel-based proteome separation technologies in an effort to alleviate the shortcomings of 2-D PAGE. In addition, traditional Chinese medicines (TCMs), due to their long period of clinical testing and reliable therapeutic efficacy, are attracting increased global attention. However, hundreds or even thousands of components are usually present in TCMs, which results in great difficulties of separation. As a mainstream separation tool, multidimensional liquid separation systems have shown powerful separation ability, high peak capacity, and excellent detectability in the analysis of complex samples including biological samples and TCMs, etc. Therefore, this review emphasizes the most recent advances in multidimensional liquid chromatography and capillary electrophoresis-based separation techniques, and the corresponding applications in proteomics and TCMs. In view of the significant contributions from Chinese scientists, this review focuses mainly on the work of Chinese scientists in the above fields.

Abstract
As the cost of drug development is always many times more than that of drug discovery, predictive methods aiding in the screening of bioavailable drug candidates are of profound significance. In this paper, a novel method for screening bioactive compounds from traditional Chinese medicines (TCMs) was developed by using living cell extract and gas chromatography (GC)-mass spectrometer (MS). The method was validated by using elemene emulsion injection (EEI), a typical TCM with known active compound, to interact with murine ascites hepatocarcinoma cell strain with high metastatic potential (HCa-F). Finally, the method was applied to screen the bioactive compounds from multi-component zedoary turmeric oil and glucose injection (ZTOGI). After HCa-F cells was incubated in ZTOGI, ethyl acetate (EtOAc) was used to extract the compounds in the cells for GC-MS analysis. Fourteen compounds were detected in the desorption eluate of HCa-F cell extract of ZTOGI, and further identified by MS. Curzerene and beta-elemene were found to be two major bioactive compounds in ZTOGI. These results show that the method developed may be applied to quickly screen the potential bioactive components in TCMs interacting with the target cells.

Abstract
A mode of comprehensive 2-D LC was developed by coupling a silica-bonded HSA column to a silica monolithic ODS column. This system combined the affinity property of the HSA column and the high-speed separation ability of the monolithic ODS column. The affinity chromatography with HSA-immobilized stationary phase was applied to study the interaction of multiple components in traditional Chinese medicines (TCMs) with HSA according to their affinity to protein in the first dimension. Then the unresolved components retained on the HSA column were further separated on the silica monolithic ODS column in the second dimension. By hyphenating the 2-D separation system to diode array detector and MS detectors, the UV and molecular weight information of the separated compounds can also be obtained. The developed separation system was applied to analysis of the extract of Rheum palmatum L., a number of low-abundant components can be separated on a single peak from the HSA column after normalization of peak heights. Six compounds were preliminarily identified according to their UV and MS spectra. It showed that this system was very useful for biological fingerprinting analysis of the components in TCMs and natural products.

Abstract
A hyphenated method for the isolation and identification of components in a traditional Chinese medicine of Honeysuckle was developed. Ion-exchange chromatography (IEC) was chosen for the fractionation of Honeysuckle extract, and then followed by concentration of all the fractions with rotary vacuum evaporator. Each of the enriched fractions was then further analyzed by reversed-phase liquid chromatography-atmospheric pressure chemical ionization mass spectrometer (RPLC-APCI/MS) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) with matrix of oxidized carbon nanotubes, respectively. It can be noted totally more than 117 components were detected by UV detector, APCI/MS and MALDI-TOF/MS in Honeysuckle extract except the 145 components identified by MALDI-TOF/MS alone with this integrated approach, and 7 of them were preliminary identified according to their UV spectra and mass spectra performed by APCI/MS and MALDI-TOF/MS, respectively. The obtained analytical results not only indicated the approach of integration IEC fractionation with RPLC-APCI/MS and MALDI-TOF/MS is capable of analyzing complex samples, but also exhibited the potential power of the mass spectrometer in detection of low-mass compounds, such as traditional Chinese medicines (TCMs) and complex biological samples.

Abstract
Effective components, ligustilide and butylidenephthalide, from Ligusticum Chuanxiong (Ligusticum wallichii Franchat, Umbelliferae) were screened and identified by using a cell membrane chromatography (CMC) and a gas chromatography/mass spectrometry (GC/MS). The components showed the effects of inhibiting vasoconstriction in vitro on rat abdominal aorta segments. The screening procedure was performed in a rat artery CMC column (50 mm x 2.0 mm I.D.) with a sodium phosphate buffer (pH 7.4) as mobile phase at 37 degrees C. The identification was accomplished by a DB-5MS 30 m capillary column (0.25 mm I.D., 0.25 microm film thickness) with helium as carrier gas operating under program control temperature and electron impact ionization mass spectrometer in a scan mode. Results demonstrated that ligustilide and butylidenephthalide can act on rat artery cell membrane similar to verapamil in CMC system. They significantly inhibited the vasoconstrictions induced by norepinephrine bitartrate (NE) and calcium chloride (CaCl2). The relaxing effect of ligustilide on the NE- and CaCl2-induced constrictions is more potent than that of butylidenephthalide. Ligustilide and butylidenephthalide seem to be the two main effective components of Ligusticum Chuanxiong as a traditional Chinese medicine for treating blood vessel diseases.

Each of the enriched fractions was then further separated on an ODS column with detection of UV absorbance and atmospheric pressure chemical ionization mass spectrometer (APCI/MS), respectively, and also analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) with matrix of oxidized carbon nanotubes. Totally more than 188 components in P. corylifolia extract were detected with this integrated approach, and 12 of them were preliminary identified according to their UV spectra and mass spectra performed by APCI/MS and MALDI-TOF/MS. The obtained analytical results not only demonstrated the powerful resolution of integration IEC fractionation with reversed-phase liquid chromatography (RPLC)-APCI/MS and MALDI-TOF/MS for analysis of compounds in a complex sample, but also exhibited the superiority of APCI/MS and MALDI-TOF/MS for identification of low-mass compounds, such as for study of traditional Chinese medicines (TCMs) and metabolome.

Abstract
Biofingerprinting chromatogram analysis, which is defined as the comparison of fingerprinting chromatograms of the extract of traditional Chinese medicines (TCMs) before and after the interaction with biological systems (DNA, protein, cell, etc.), was proposed for screening and analysis of the multiple bioactive compounds in TCMs. A method of microdialysis sampling combined with high performance liquid chromatography (HPLC) was applied to the study of DNA-binding property for the extracts of TCMs. Seven compounds were found to bind to calf thymus DNA (ct-DNA) from the TCMs of Coptis chinensis Franch (Coptis), but only three ones from Phellodendron amurense Rupr. (Phellodendron) and none from Sophoraflavescens Ait. (Sophora) to bind to ct-DNA, respectively. Three of them were identified as berberine, palmatine and jatrorrhizine and their association constants (K) to ct-DNA were determined by microdialysis/HPLC. Competitive binding behaviors of them to ct-DNA were also investigated.

Abstract
The screening and analysis of bioactive components in traditional Chinese medicines (TCMs) is very important not only for the quality control of crude drugs but also for elucidating the therapeutic principle. In this study, a method for screening potential active components from TCMs was developed by using biomembrane extraction and high performance liquid chromatography. Based on the methodology, aqueous extract of Angelica sinensis (WEAS) was used, and four compounds were detected by HPLC in the desorption eluate of red cell membrane extraction for WEAS. The compounds were identified as ferulic acid, ligustilide, senkyunolide H and senkyunolide I based on their UV, MS and NMR spectra. Actually, ferulic acid and ligustilide are considered as major active components in Angelica sinensis. Therefore, this method may be applied to predict the potential bioactivities of multiple compounds in TCMs simultaneously.

Abstract
A comprehensive two-dimensional liquid chromatographic separation system based on the combination of a CN column and an ODS column is developed for the separation of components in a traditional Chinese medicine (TCM) Rhizoma chuanxiong. Two columns are coupled by a two-position, eight-port valve equipped with two storage loops and controlled by a computer. The effluent is detected by both the diode array detector and atmospheric pressure chemical ionization (APCI) mass spectrometer. More than 52 components in the methanol extract of R. chuanxiong were resolved and 11 of them were preliminary identified according to their UV and mass spectra.

Abstract
The volatile chemical constituents in traditional Chinese medicine (TCM), Artemisia capillaris herba, were determined by gas chromatography-mass spectrometry (GC-MS). The acquired two-dimensional data were resolved by correlative chemometric resolution methods. The noise in the raw data is pretreated by roughness penalty smoothing method. With the data denoised, heteroscedastic noise and signal-to-noise ratio were decreased apparently, which was favorable to the determination of component number. The selective range can be extracted from rankmap obtained by fixed size moving window evolving factor analysis (FSMWEFA) conveniently. The overlapped chromatographic peaks were resolved into pure chromatograms and pure spectra with evolving window orthogonal projection (EWOP). The purity of the resolved pure spectra were improved furthermore with the heteroscedastic noise decreased through roughness penalty smoothing method, although the basic structure of the raw data changes little. Qualitative analysis was performed by similarity search in NIST147 and Willey library. Pure chromatograms are in favor of quantitative analysis, which was obtained by total volume integration. Forty-two of seventy-five separated constituents in essential oil, accounting for 89.03% of the total content, were identified. The result proves the combined approaches to be powerful for the analysis of complex herbal samples.

Abstract
Immobilized liposome chromatography (ILC) was used to screen and analyze permeable compounds in traditional Chinese medicines (TCMs), testing extracts from Radix Angelica Sinensis. More than 10 peaks were resolved based on their interactions with the ILC stationary phase, a system which mimics biomembranes; this means that more than 10 components in Radix Angelica Sinensis extract have significant retention on an ILC column. Two of them, ligustilide and ferulic acid, were identified from their MS spectrum and with standard samples. A possible molecular structure of another component retained on ILC was also preliminarily identified as 3-butylidene-4,5-dihydro-2(1,3H)-1-isobenzofuranol according to its MS spectrum, hydrophobicity and 1H NMR spectrum. Of all detected components, ligustilide had the best penetration ability through the biomembrane. The effects of pH, column temperature, and ionic strength on the chromatography of methanolic extracts of Radix Angelica Sinensis were also investigated. It was found that the separation selectivity on ILC is strongly affected by the eluent pH, but only slightly by the column temperature and ionic strength.

Abstract
Molecular biochromatography with alpha1-acid glycoprotein (AGP) stationary phase was proposed to screen and analyse the biologically active components in traditional Chinese medicines (TCMs) with extracts from Radix Salviae miltiorrhizae as a tested sample. More than ten peaks were resolved based on their affinity to AGP. The effects of concentrations of acetonitrile, pH, concentration of inorganic salt and temperature on the retention behaviors of several major active components were also investigated, and it was found that the hydrophobic effect is the major contributor to retention. Tanshinone IIA was identified as one of the principal bioactive components, which is the marker for the quality control of Radix Salviae miltiorrhizae and a complicated remedy named YiXiTongMai. The amount of tanshinone IIA in Radix Salviae miltiorrhizae and YiXiTongMai determined by this method was 2.9 mg/g (net weight, RSD 4.9%, n=5) and 0.078 mg/g (net weight, RSD 2.5%, n=3), respectively. The possibility for fast differentiation of the TCM sources was also studied by the comparison of the fingerprint of chromatograms for eight typical TCMs on the AGP column. It was observed that different TCMs showed different fingerprint characteristics. Even for the same plant, Rhizoma cimicifugae from three different geographical sources, although there were common characteristics, distinct differences in types and concentrations of biologically active components were clearly observed. It was shown that molecular biochromatography was an effective and fast way for the analysis and screening of biologically active compounds in traditional Chinese medicines.
