Abstract
OBJECTIVE The aim: Different gels composed of benzydamine and flavonoids that were developed for treatment of periodontal diseases in the orthodontic patients will be compared regarding their effects on survival of mammalian cells of various tissue origin and their DNA intactness. PATIENTS AND METHODS Materials and methods: Effect of different variants of patented gel composition «Benzidaflaziverdine» including a gel base and «Proteflazid®» containing flavonoids and benzydamine hydrochloride in powder form («T-Sept®») towards survival (MTT) of murine BALB-3T3 fibroblasts, J774.2 macrophages, human HaCaT keratinocytes was studied. Their effect on nativity of DNA of J774.2 macrophages was evaluated using DNA-comet assay. RESULTS Results: Three gel compositions were used. Sample 1 was prepared on gel basis including benzydamine in liquid form and demonstrated inhibitory effect towards pseudonormal murine BALB-3T3 fibroblasts and murine J774.2 macrophages, however, normal human НаСаТ keratinocytes were resistant to its action. Sample 2 included BH in powder form and it did not affect significantly НаСаТ keratinocytes аnd BALB-3T3 fibroblasts, but it suppressed J774.2 macrophages. Sample 3 («Benzidaflaziverdine») was developed and patented by us as a gel composed of benzydamine in powder form and flavonoid drops «Proteflazid®». It did not suppress tested mammalian cells and was not genotoxic (measured as % of DNA in comet tail and Olive Tail Moment) for murine J774.2 macrophages. CONCLUSION Conclusions: Inclusion of flavonoids in gel composition «Benzidaflaziverdine» blocked cytotoxic and genotoxic actions of benzydamine. Developed gel com¬position might be efficient in clinical periodontology, in particular, for treatment of periodontal diseases in orthodontic patients.

Abstract
In order to explore appropriate measures to promote germination after the harvest of Epimedium pseudowushanense, 6-BA, urea, ammonium bicarbonate and GA₃ were chosen to spray on the root and rhizomes, and then the biological indicators such as branches, leaf length, leaf width, plant height and so on, were measured in different periods, and the contents of epimedin A, epimedin B, epimedin C and icariin in the dry leaves were detected by HPLC. Results showed that 6-BA 90 mg·L⁻¹(B1), 6-BA 60 mg·L⁻¹(B2),6-BA 30 mg·L⁻¹+urea 300 mg·L⁻¹ (C1), 6-BA 60 mg·L⁻¹+urea 300 mg·L⁻¹(C2),6-BA 60 mg·L⁻¹+ ammonium bicarbonate 300 mg·L⁻¹(C4) significantly increased bud germination in the early period, and the plants quickly set up new system of photosynthesis, the branches in a month of which were higher than the control group respectively by 165.9%, 115.76%, 103.86%, 104.50%, 81.67%.However the branches developed the next year and the dry weight of leaves per plant in group B1 and B2 were much lower than that in control group. The groups that use 6-BA and nitrogen at the same time reaped a good yield of leaves even though the treatment had no significant influence on the branches developed the next year. The dry weight of leaves of C1, C2, C4 treatments were 36.80%, 32.84%, 45.97% more than the control group respectively. Therefore, C1, C2 and C4 treatments are the more appropriate to promote recovery after harvest. Furthermore, different groups, except 10 mg·L⁻¹ 6-BA treatment significantly reduced the content of epimedin C, other groups didn't have any significant effect on the contents of such flavonoids.

Abstract
The study is aimed to fully analyze antioxidant activty and stability of color-related components from Dendrobium officinale flower. The contents of anthocyanins,carotenoids and flavonoids of 10 varieties including whole flower and labellum of D.officinale flower were detected using UV visible spectroscopy technique and evaluated for their 1,1-diphenyl-2-picrylhydrazyl radical (DPPH·), superoxide anion radical (·O⁻₂) and hydroxy radical (·OH) scavenging activty. And the effects of 4 kinds of metal ions (Cu²⁺, Mg²⁺, Al³⁺,K⁺) and 2 kinds of food additives were investigated on the stability of anthocyanins pigment from D.officinale flower. The results indicated that the flower of D.officinale contained anthocyanins,carotenoids and flavonoids,and their contents in different parts of different families varied. The content of anthocyanins (1 330.9 μg·g⁻¹) in labellum was significantly higher than that in the whole flower (696.3 μg·g⁻¹). The content of carotenoids was positively correlated with the content of anthocyanins,and there was significant positive correlation between the scavenging capacities of the three free radicals and the contents of anthocyanin,respectively (0.415,0.384,0.455). The Cu²⁺, Mg²⁺, Al³⁺, K⁺ and glucose showed significant color-enhancing effect and could increase the stability of anthocyanin in D.officinale flower,while ascorbic acids showed remarkably degradation effect of anthocyanin in D.officinale flower.

Abstract
Nitrogen nutrition divided into concentrations and forms for Epimedium pseudowushanense was studied under hydroponic conditions. There were 7 nitrogen concentrations treatments(N0-N6)which nitrogen concentration was 0, 2.5, 5.0, 7.5, 10.0, 13.0 mmol•L⁻¹, respectively, and 5 nitrogen forms and proportions treatments (T1-T5) which NO3-N/NH4-N was 5∶0, 4∶1, 2.5∶2.5, 1∶4, 0∶5 respectively, the total nitrogen applied was 5 mmol•L⁻¹. The results showed that along with the increase of nitrogen concentration, biomass (dry weight) and leaf dry weight increased, which in N5 treatment was 29%, 23% higher than those in N0 and 36%, 23% higher than those in N4 respectively, but not significantly different from N6 treatment. Roots and stem dry weights did not change significantly. Pn and the contents of photosynthetic pigments were higher in N3-N5 treatments. Epimedin A, B, C, icariin and total flavonoids contents were the lowest in N3 treatment, suddenly increase in N4 treatment and only a little change between N4-N6 treatments. N5 treatment with the highest epimedin C content was 131% higher than N3 treatment with the lowest epimedin C content (P<0.05). While in the nitrogen forms and proportions treatments, biomass, leaf and stem dry weights were the highest in T3 treatment and lower in T1 and T5 treatments, without significance between T1 and T5 treatments. These indicators in T3 treatment were more than 30% higher than those in T1 treatment. The impact of nitrogen concentrations was greater than nitrogen forms on flavonoids. epmedin C content was the highest in T1 treatment, only 5%-8% higher than that in T2-T5 treatments (no significance between 4 treatments). Epimedin A, B, icariin and total flavonoids contents were higher in T1 treatment, the lowest in T2 treatment, those in T1 treatment was 41%, 62% and 27% higher than T2 treatment respectively (P<0.05). In a conclusion, E. pseudowushanense is a high nitrogen tolerant plant, 10.0 mmol•L⁻¹ was the boundary point between growing general to well and the optimal nitrogen concentration for it was 10.0-13.0 mmol•L⁻¹. Besides, it prefers to grow in NO-3 plus NH+4 and the optimal proportion was 2.5∶2.5.

Abstract
To establish a HPLC-MS/MS quantitative method for analysis of 8 constituents in rat bile. The method was applied in the biliary excretion study after oral administration of Desmodii Styracifolii Herba extract. The rat bile samples were collected during 0-1, 1-2, 2-4, 4-6, 6-8, 8-12, 12-24 h. Diamonsil C₁₈column (4.6 mm×150 mm, 5 μm) was adopted and eluted with methanol and 0.01% acetic acid in a gradient mode. The flow rate was 0.8 mL•min⁻¹, and the column temperature was set at 40 ℃. The detection was carried out by a triple quadrupole linearion trap mass spectrometer in the negative ion mode with an electrospray source. Multiple reactions monitoring (MRM) mode was employed. The calibration curves showed a good linearity, with correlation coefficients (r≥0.991 5) for all of the analytes within the concentration range. The intra-day and inter-day precisions (RSD) were both less than 15%, and the accuracies (RE) ranged from -15% to 15%. The method had a good stability, and was suitable for the content determination of 8 constituents in rat bile. The extraction recoveries of the 8 analytes were more than 63.2%, and the RSD of IS-normalized matrix factors were no more than 15%, which met the requirements for analysis. According to the biliary excretion study, the bile excretion rates of the 8 analytes were relatively low, with great difference among the individuals. The results showed that the established method was simple, selective and specific, thus could be applied in the biliary excretion study of the 8 analytes in rat bile.

Abstract
Five main flavonoids of Hebei Xiangju were studied using the Density Functional Theory (DFT) B3LYP method with 6-311 G (d) basis set.Their activities were analyzed based on molecular structure,bond dissociation energy (BDE),natural orbital charge distribution (NBO),bond order and the energy gap between HOMO and LUMO. The results showed that the existing of intra molecular hydrogen bond in B ring can improve the antioxidant activity of the flavonoids, at the same time, the hydroxyl groups on the glycosides do not have the activity of eliminating free radicals, but decrease the total molecular antioxidant activity. As a result, the antioxidant ability order of the five flavonoids compounds is luteolin< luteolin-7-O-glucoside< apigenin < acacetin < acacetin-7-O-glucose, which is agreement with the experimental conclusion reported in literature. The results showed that the DFT method can provide theoretical guidance for the selection of natural flavonoid antioxidants.

Abstract
The aim of this study was to develop a simple, sensitive ultra performance liquid chromatography mass spectrometry (UPLC-MS/MS) method for the determination of syringaresinol, N-trans-feruloyltyramine, chelerythrine chloride, sinomenine, coptisine chloride, sanguinarine, chelidonine, magnolflorine, allocryptopine, protopine, farrerol, stylopine and dihydrosanguin-arine in Tong'an injection (TAI), which could be used for the quality control of TAI. The UPLC analysis was performed on Agilent Zorbax SB-Aq column (2.1 mm×150 mm,3.5 μm), with 0.1% formic acid solution (A) -acetonitrile (B) as the mobile phase for gradient elution (0.01-2 min, 5%B; 2-8 min, 5%-30%B; 8-11 min, 30%-95%B; 11-13 min, 95%B; 13-13.1 min, 95%-5%B; 13.1-14 min, 5%B). The flow rate was 0.5 mL•min⁻¹, and the column temperature was 25 ℃; multiple reaction monitoring (MRM) was performed in electrospray ion source positive ion mode for quantitative determination. The calibration curves for the above thirteen compounds showed good linear relationship in corresponding mass concentration range (r>0.999 0). The average recovery rate of the compounds ranged from 95.70% to 104.8%, with RSD of less than 1.9%. The contents of thirteen active components in 10 batches of TAI were 0.021 2-0.029 0, 0.001 7-0.002 3, 0.000 9-0.001 3, 5.952-6.205 2, 0.195 4-0.240 5, 0.002 0-0.002 9, 0.693-0.798 2, 0.069 3-0.078 2, 0.089 29-0.102 9, 0.386 5-0.420 1, 0.014 3-0.015 9, 0.755 3-0.842 1, and 0.008 2-0.011 2 g•L⁻¹ respectively. Methodology validation proved that this method was simple, rapid, sensitive and accurate, which can be used to provide reference for the comprehensive evaluation of TAI quality. The determination results of 10 batches of TAI showed the content of each batch had no significant difference. The results may provide a basis for the quality control of TAI.

Abstract
In this study, an HPLC-MS/MS method was developed and validated for simultaneous determination of six iridoids and four flavonoids in batches of Lonicerae Flos samples. Chromatographic separation was performed on a Shiseido Capcell Pak-C₁₈ column (4.6 mm×250 mm, 5 μm). 0.1% Aqueous formic and acid (A) and acetonitrile (B) were adopted as mobile phase. Detection was carried out on a triple quadrupole mass spectrometer in the negative ion mode using an electrospray source. Multiple reaction monitoring (MRM) mode was employed. The developed method showed good linearity (R² ≥0.999 0) for all the analytes within the test ranges and the limits of quantification (LOQs) ranged from 7.4 to 31.0 μg•L⁻¹. The recoveries varied between 94.16% and 105.3%. The quantitative data indicated that the total content of iridoids (0.338%-1.440%) was much higher than that of flavonoids (0.015 4%-0.057 5%) in all samples. Moreover, it was found that there were significant differences in the content of six compounds among the samples from three different original plants, which might provide scientific evidences for the origin identification and quality control of Lonicerae Flos.
