摘要
为了制定海南习用药材酸藤子的质量标准,以2020年版《中国药典》质量鉴定基本原则为指导,采用性状观察法、显微观察法、薄层色谱法、烘干法、总灰分测定法、水溶性热浸法、紫外-可见分光光度法分别研究酸藤子的性状和显微结构特征,水分、总灰分、水溶性浸出物以及总黄酮含量.明确了酸藤子性状和显微结构特征,建立了其薄层鉴别方法;拟规定酸藤子药材水分不得超过13.0％,总灰分不得超过12.0％,水溶性浸出物含量不得少于20.0％,总黄酮含量不得少于1.3％.初步拟定了海南习用药材酸藤子质量标准,为酸藤子进一步的质量控制和药用开发提供参考.
Abstract
In order to establish the quality standard of Embelia laeta,a native traditional medicine in Hainan,charac-ter observation method,microscopic observation method,thin layer chromatography,drying method,total ash determi-nation method,water soluble hot leaching method,ultraviolet-visible spectrophotometry were used to study character and microscopic structure characteristics,water content,total ash,water soluble extract and total flavonoid content of E.lae-ta based on the basic principles of quality verification of Chinese Pharmacopoeia(2020 edition).The characters and mi-crostructure of E.laeta were clarified,and its thin layer identification method was established.It is suggested that the wa-ter content of E.laeta should not exceed 13.0％,the total ash content should not exceed 12.0％,the content of water-soluble extract should not be less than 20.0％,and the total flavonoid content should not be less 1.3％.This study prelim-inarily formulates the quality standard of E.laeta folkly used in Hainan,and provides reference for further quality control and medicinal development of E.laeta.
