Macroscopic and Microscopic Identification Study of Dongchongxiacao (Cordyceps sinensis ( Berk. ) Sacc.) and Its Counterfeits / 中国药学杂志

ABSTRACT

OBJECTIVE: To research for the identification of Dongchongxiacao [Cordyceps sinensis( Berk.) Sacc.] and its counterfeits-processed materials from Cordyceps taii Liang et Liu. METHODSE: On the basis of the specimens of Dongchongxiacao and four types of counterfeits, the macroscopic and microscopic identification methods were studied, including the comparison of the macroscopic features, such as insertion position of stroma, colour of caterpillar part, abdominal leg, and the microscopic features such as the transverse section of the stroma, the caterpillar's body wall and the planta of abdominal leg. RESULTS: The differences between Dongchongxiacao and four types of counterfeits were obvious in macroscopic and microscopic features. CONCLUSION: Dongchongxiacao and its counterfeits-processed materials from Cordyceps taii Liang et Liu. can be identified by the differernces of macroscopical and microscopical fetures.
