摘要
本文对浙贝母Fritillaria thunbergii Miq.等20种贝母的鳞叶上(内)表皮进行了显微观察,发现种间在表皮细胞形状、大小和垂周壁部位角质栓(cuticular peg)的形状,大小和排列等方面有一定区别,可作为新的鉴别依据。全文除描述外,列出检索表,并附主要特征图。
Beimu, a famous traditional Chinese drug, has been used as an antitussive and expectorant for a long time and it is derived from a number of species of Fritillaria. So it is difficult to identify, exactly the botanical origin of the commercial crude drugs by means of macroscopic examination. This paper deals with the microscopic identification of the upper epidermis of the scales of 20 species. The result showed that these species are different from each other in the shape and size of the epidermal cells, the shape,size and arrangement of the cuticular peg. Moreover, it was found that the anticlinal wall of the epidermal cells is not bead- thickened, but cuticular peg formed by cuticle.
