Comparative on the Moisture Content and Indicator Components of Ten Kinds of Ganoderma Lucidum on Hainan Market
Objective Study the quality differences of ten common commercially available Ganoderma lucidum in Hainan,laying the foundation for drafting local medicinal material standards and providing reference for further development of Ganoderma lucidum.Method Purchase 30 batches of ten common commercially available Ganoderma lucidum in Hainan,describe their appearance charac-teristics,and refer to the inspection methods under the Ganoderma lucidum standards in the Chinese Pharmacopoeia(2020 edition).After appropriate optimization,determine the moisture,triterpenes,and sterols content in Ganoderma lucidum as the main indicators for evaluating the quality of Ganoderma lucidum.Result The precision RSD of the method was 1.9％,and the recovery rates for low,medium,and high concentrations were 96.4％,95.2％,and 98.3％,respectively.When measuring the Ganoderma lucidum test sample,one batch had a moisture content exceeding 17.0％,and four batches had triterpenoid and sterol content below 0.50％.Con-clusion The Chinese Pharmacopoeia only includes Zizhi and Chizhi.When drafting standards for other commercially available Ganoder-ma varieties,the limit range can be appropriately modified based on the pharmacopoeia standards.The government should strengthen supervision,gradually standardize the Ganoderma market,revise and improve local medicinal material quality standards,in order to further develop and utilize Ganoderma resources.
