植物叶表面特征在生药鉴定研究中的意义 Ⅰ.7种唇形科叶、草类生药的鉴定

Effection of the Leaf Surface Characters of Plants on Studies of Crude Drugs Ⅰ. Identification of 7 Species of Folium and Herba From Family Labiatae

对唇形科7种叶、草类生药,海州香薷、石香薷、泽兰、薄菏、广藿香、益母草和紫苏的叶表面特征进行了显微观察,结果表明叶表面纹理及表皮附属物的形态、表面突起和纹理对唇形科叶、草类生药有鉴别意义。光学显微镜与扫描电镜配合使用可提高叶、草类生药鉴定的准确性。

This paper deals with identification of 7 species of Folium and Herba from Family Labiatae viz. , Elsholtzia splendens Nakai ex F. Maekawa. Mosla chinensis Maxim. , Lycopus lucidus Turcz. var. hirths Regel, Mentha haplocalyx Briq. , Pogotemon cablin (Blance) Benth. , Leonurus heterophyllus Sweet and Perilla frutescens (L.) Britt. The leaves of the 7 species were observed under light microscope and scanning electron microscope. The results showed that the 7 species can be distinguished obviously, by the characters of the cuticle covered epiodermis cell and the features of trichomes. The results indicated also that the accuracy of identification of folium and herba will be improved through using light microscope and scanning electron microscope at the same time.
