波棱瓜子的原植物和显微鉴别研究

目的:为藏药波棱瓜子的药材鉴定提供依据。方法:应用粉末制片、徒手切片和石蜡切片进行研究,找出组织和粉末特征。结果:商品调查表明,波棱瓜子各地用药品种基本一致,但也有用木鳖子、王瓜、西藏赤爬等葫芦科其他属植物种子误作波棱瓜子的情况。结论:通过药材性状、组织、粉末特征能将波棱瓜子、木鳖子、苦瓜子、西藏赤爬种子予以准确区分。

Morphological and histological studies of Herpetospermum pedunculosum seeds and other substitutes

Objective: To provide new evidences for the identification of Herpetospermum pedunculosum seeds and other substitutes. Method: Microscopic examination of the cross sections and powers of the seeds of H. pedunculosum, Momordica charantia, Thladiantha setispina and M. cohinchinensis were made to characterize the drug materials. Result and conlusion: The external and internal structure of T. setispina and M. charantia were studied for the first time. Two types of different branched starry sclereids was found in M. cohinchinensis. Comparative studies on external and internal structure were carried out on seeds of the 4 species. As a result, they could be distinguished by external characteristics such as shape, size and color of their seeds, and by internal structure such as size and type of sclereid, epidermis and sub-epidermis cell of seed coat.
