摘要(Abstract):

目的:提供一种既简单又方便的方法,来区分正品冬虫夏草及其混淆品。方法:采用性状鉴别法,观察虫草类的虫体及子座,以及粉末显微鉴别法。结果:性状鉴别方面,冬虫夏草的正品及混淆品可通过子座的有无或形状,菌膜、虫体气门的排列方式和虫体颜色等特征区分。显微鉴别方面,则可从虫体体壁细胞的表面纹理,及背、足部短刚毛的有无、长短、形状和排列方式等各方面鉴别其品种。结论:该方法简单易行,可用于鉴别冬虫夏草的正品及混淆品。
Objective:To provide a rapid,simple,accurate and reproducible identification method from which Cordyceps sinensis can be distinguished from other species.Method: To observe the larva and stroma of Cordyceps family with macroscopic identification method,and with powder microscopic identification method.Result and Conclusion: For macroscopic,only stroma of C.sinensis is mostly non-inflated,and un-obtuse at the tip,the caterpillar annulations of C.sinensis and the C.gracilis is distinct,about 20-30,and feet of above two are 8 pairs,4 of 8 pairs are relatively distinct.The above appearance shows its unique characteristic.For microscopic identification,only C.sinensis exists microtrichia,the tip is pointed.The arranging order of stubby setae is irregular,the tip is blunt while the basal is gradually broader;the top of some setae bends slightly like a hook.
