Study on quality standard for Embelia laeta,a native traditional medicine in Hainan
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.
