软枝黄蝉与马缨丹的生药学研究

目的对软枝黄蝉和马缨丹两种药用植物进行生药学研究,为有关部门临床应用、中毒抢救和开发利用提供参考资料。方法采用性状鉴定、显微鉴定、理化鉴定。结果软枝黄蝉根横切面木栓层极宽,明显分为两层;茎横切面具柱鞘纤维;粉末中淀粉粒和草酸钙簇晶极多。马缨丹根横切面射线细胞结构较特殊,茎横切面四方形,且具有厚壁组织;粉末中单细胞非腺毛众多,分泌细胞中含橙黄色油滴。结论以上生药学特征可作为软枝黄蝉和马缨丹的主要鉴定依据。

Pharmacognosic Research on Allamanda cathartica L. and Lantana camara L.

Objective To conduct pharmacognosical studies on the roots and leaves of Allamanda cathartica L. and Lantana camara L. for the purpose of offering references to their clinical use, rescuing poisoned persons , development and usage. Methods The plants' characters and their microscopic structures, as well as their physicochemical properties were studied. Results Phellem in horizontal sections of Allamanda cathartica L. was thick, clearly consisting of two layers; and many starch grains and crystal clusters of calcium oxalate were found in the cross sections of its stems and its powder. Structures of cells of rays in the horizontal sections of Lantana camara L. were relatively exceptional; sclerenchymae was discovered in the square cross sections of its stems; its powder possessed unicellular non-glandular hairs, in which secretory cells containing orange oil drops were found. Conclusion The result can be taken as the basis for the identification of the two plants.
