Abstract:
OBJECTIVE： To establish the quality standard of Sabina vulgaris， and to provide reference for its quality control. METHODS： Totally 9 batches of S. vulgaris were collected from Inner Mongolia area. The characteristics of S. vulgaris samples were observed and microscopic identification was conducted for the transverse section and powder of its branches and leaves. TLC was used for qualitative analysis of S. vulgaris. The contents of water， total ash， acid-insoluble ash and alcohol-soluble extract in S. vulgaris were determined according to the method stated in 2015 edition of Chinese Pharmacopeia （part Ⅳ）. The contents of quercetin and amentoflavone in S. vulgaris were determined by HPLC. RESULTS： The branchlets of S. vulgaris were cylindrical or rhombic， with varying length of thorns， dark green or yellowish green. The microscopic observation showed that the epidermal cells of scale leaves were arranged orderly； there were larger cavities in the middle of scale leaves， large cells in spongy tissue； epidermal cells were rectangular with more stomata and large guard cells. Results of TLC showed that the spots of the same color were found in the corresponding positions of chromatogram for substance control （dendrooside and rutin）. In the 9 batch of samples， the contents of water were 3.2％-5.6％； the contents of total ash were 3.4％-5.8％； the contents of acid-insoluble ash were lower than 0.8％； the contents of alcohol-soluble extract were 28.0％-33.8％； the contents of quercetin were 0.11％-0.28％； the contents of amentoflavone were 0.15％-0.25％. CONCLUSIONS： It is preliminarily proposed that the content of water in S. vulgaris is not more than 8.0％； the content of total ash is not more than 7.0％； the content of alcohol-soluble extract is not less than 24.0％； the content of quercetin is not less than 0.11％； the content of amentoflavone is not less than 0.15％. Established standard can be used for the quality control of S. vulgaris.
