ABSTRACT
OBJECTIVE:To improve the quality standard of Compound shougong powder.METHODS:Gekko japonicas and Armeniaca mume were identified by microscopic identification.TLC method was adopted to identify processed Fallopia multiflora qualitatively.The content of 2,3,5,4-tetrahydroxystilbene-2-O-β-D-glucoside (stilbene glycoside) was determined by HPLC.The determination was performed on Agilent Zorbax Eclipse XDB-C18 column with mobile phase consisted of acetonitrile-water (19 ∶ 81,V/V) at the flow rate of 1.0 mL/min.The detection wavelength was set at 320 nm,and column temperature was 25 ℃.The sample size was 10 μL.RESULTS:Microscopic characteristics of skin fragments and scales of G.japonicas and the pollen grains of A.mume were significant without interference from negative control.TLC spots of F.multiflora were clear and well-separated without interference from negative control.The linear range of stilbene glucoside were 23-368 μg/mL (r=0.999 9).RSDs of precision,stability and reproducibility tests were all lower than 1.0％.The recoveries ranged 98.69％-101.61％ (RSD=0.94％,n =9).CONCLUSIONS:Improved standard can effectively control the quality of Compound shougong powder.

ABSTRACT
Objective To study the immunomodulatory property of Compound Shougong powder(SGS) on S180 tumor-bearing mice.Methods The S180 model of tumor-bearing mice by Kunming mice were prepared.Then,the tumor-bearing mice were randomized into the model group,positive control group,and SGS groups (29.25g/kg,19.50g/kg,9.75g/kg).Besides the normal group,the other groups were used intragastric administration of into tumor-bearing mice by one time,14 consecutive days.The carbon clearance,quantitative hemolysis and DNFB induced delayed-type hypersensitivity were applied to assay effects of SGS on nonspecific immunity,humoral immunity and cellular immunity.Results Compared with the model control group,in the SGS groups,the tumor-bearing mice with spleen and thymus index of organ improved (all P ＜ 0.05),and the clearance index and values of phagocytic index were elevated(all P ＜0.05),and the productions of IgM and IgG in serum and hemolysin in splenocytes were enhanced(all P ＜0.05),and the percentages of T cells expressing CD4+,CD8+ and the ratio of two subset of T lymphocyte increased,and the IL-2 production of spleen lymphocytes was also improved (all P ＜ 0.05).Conclusion SGS showed significant immunomodulatory property on tumor-bearing mice through specific and nonspecific immunity.
