益母草类药材的性状鉴定

The Descriptions Identification of “Yimu Cao”

选择花序下苞叶以及宿存花萼作为主要鉴别特征,区分了来源于同属8种l变种的益母草类药材,结果比较可靠。

Remained but entire bracts beneath the inflorescence and the persistent calyxes were selected as primary charac- teristics to distinguish 'Yimu Cao' .which derived from 8 species and 1 variety in the same genus Leoruaus. The results were reliable.
