Establishment of quality standards for the tropical herbs Lignosus rhinocerus
This study aims to establish the quality standard of Lignosus rhinocerus,a tropical medicinal herb.In this study,the qualitative identification of traits,microstructure and thin-layer chromatographic characteristics of Lignosus rhi-nocerus was carried out.The contents of water,total ash and extract contents of Lignosus rhinocerus were determined by according to the methods of Chinese Pharmacopoeia in 2020.UV spectrophotometric method was applied for the determi-nation of total sugars content.The quality standards of Lignosus rhinocerus are that the moisture content shall not exceed 13.0％,the total ash shall not exceed 2.0％,and the content of water-soluble leachate shall not be less than 3.0％;and with dextrose anhydrous as the control,the total sugars content of Lignosus rhinocerus should not be less than 0.45％.The results of the study established a proprietary thin-layer identification method for Lignosus rhinocerus and derived the optimal extraction process for the total flavonoids of Lignosus rhinocerus The method is reproducible,simple and effi-cient,and can be used for the quality control of Lignosus rhinocerus.It provides a reference for the further control of the quality of the herbs of Lignosus rhinocerus,and for the research and development of Lignosus rhinocerus.
