[Abstract]:Objective: to evaluate the authenticity, merits and demerits of Zhuang medicine fence net, and to establish the quality standard of Zhuang medicine fence net. Methods: (1) through base source identification, character identification, The pharmacognosy of hedgerow net was systematically studied by microscopic identification and physical and chemical identification. (2) according to the methods stipulated in the 2015 edition of the Pharmacopoeia of the people's Republic of China, the limited amount of medicinal materials in hedgerow net, including moisture and total ash, was examined. Acid insoluble ash, extract, etc. (3) according to the chemical pre-experimental method of traditional Chinese medicine, the composition of hedgerow net from three producing areas was pre-tested. (4) rutin was used as reference material. The content of total flavonoids in 12 batches of hedgerow in Guangxi was determined by UV-vis spectrophotometry, and the limit of total flavonoids was determined. (5) chlorogenic acid was used as reference material. The content of chlorogenic acid in 12 batches of hedgerow net in Guangxi was determined by high performance liquid chromatography (HPLC) to determine the limit of chlorogenic acid. (6) the biological activity of hedgerow net was determined by bioassay based on antibacterial titer. Results: (1) the identification of base source, character, microscope and thin layer chromatography was significant, which could be used as the basis for distinguishing the authenticity of hedgerow net. (2) the experimental results showed that the water content of hedgerow net was 6.26% and 9.96%, The moisture content of the preliminary formulation shall not exceed 11.00%; The range of total ash content is 6.31 鈮，
