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.
