豨莶草商品药材的显微鉴定

Microscopic Identification of Commercial Herba Siegesbeckiae

目的对全国9个收集地的豨莶草商品药材进行鉴定,以了解目前市场上豨莶草的真伪情况。方法采用性状鉴别与数码显微鉴定技术。结果市场上流通豨莶草均为正品,3种基原植物分别为豨莶Siegesbeckia orientalisL.、腺梗豨莶S.pubescensM ak ino和毛梗豨莶S.glabrescensM ak ino。结论豨莶草商品药材的主流品种为腺梗豨莶,占4/9,其次为豨莶和毛梗豨莶。首次采用数码成像技术拍摄了豨莶草商品药材的显微图片,真实、直观地反映了三种药材的差别。

Objective To identify the commercial drugs of Herba Siegesbeckiae collected from 9 different areas. Methods - Macroscopic and microscopic identification with digital imaging technology. Results The original plants of the commercial drugs were three species, which are, Siegesbeckia orientalis L. , S. pubescens Makino and S. glabrescens Makino. Conclusion The main current species in markets is Siegesbeckia pubescens Makino （4/9）, then are S. orientalis L. and S. glabrescens Makino. The digital photographs offered by the paper visually reflected the microscopic differences of three species.
