药用钩藤和类钩藤的比较

A Comparison Study Between Medicinal Plant Uncaria Rhynchophylla (Miq.) Miq.Ex Havil. and Uncaria Rhynchophylloides How

本文首次从植物形态、种皮纹饰的扫描电镜观察，叶柄、茎组织构造、内部次生代谢产物—吲哚生物碱等方面对茜草科Ｒｕｂｉａｃｅａｅ，钩藤属Ｕｎｃａｒｉａ的钩藤Ｕｎｃａｒｉａｒｈｙｎｃｈｏｐｈｙｌａ（Ｍｉｑ．）Ｍｉｑ．ｅｘＨａｖｉｌ．与类钩藤ＵｎｃａｒｉａｒｈｙｎｃｈｏｐｈｙｌｏｉｄｅｓＨｏｗ进行了详细比较。认为类钩藤应是独立种，钩藤碱的含量在检测量之下，不能混入钩藤同样药用。

In this paper,relationship of time-order change of subunits of seedlings in V.venosa complex and V.unijuga with flowering were analysed by'modula'method from enlightenment of wild population investigation. It was discovered that some plants broke into demarcation of form between the two speices in cultivated population of V.venosa complex, i. e. when compound leaf was consisted of one pair of leaflets, plants flowered. Plants with three or four leaflets were found in wild population of V. unijuga. Hence, authors suggested that this change of form could indicate that the two species, belonging to sect. Vicilla had directive common ancestor.
