构叶的生药学研究

目的 通过对构叶的生药学研究,为构叶的开发利用、质量标准的制定及生药学方面的研究提供依据.方法 依据形态学特征对构叶进行原植物形态、性状特征、显微特征鉴别,运用薄层色谱、紫外光谱法对构叶进行理化特征鉴定.结果 构属植物构叶的药材性状、显微特征、理化特征(薄层色谱,紫外吸收光谱)与同属植物小构叶鉴别特点有明显不同.结论 研究结果 可作为构叶生药质量标准制定的依据.

Pharmacognostic study on leaves of Broussonetia papyrifera (L.) Vent.

Objective To provide the evidence for the establishment of quality standard,pharmacognostic studies and the further utilization of the leaves of Broussonetia papyrifera(L.) Vent.through the study on their pharmacognostic characteristics.Methods The morphology,characters and microscopy characteristics of original leaves of Broussonetia papyrifera(L.) Vent.were identified according to their morphological characteristics,and their physicochemical characteristics were identified by using thin layer chromatography(TLC) and ultraviolet spectroscopy.Results The characteristics of characters,microscopic and physicochemistry(absorption spectrum of TLC and ultraviolet spectroscopy) of the leaves of Broussonetia papyrifera(L.) Vent.were much different from the leaves of Broussonetia kazinoki Sieb.et Zucc.Conclusion The study outcomes can be taken as the basis for setting up the quality standard of the leaves of Broussonetia papyrifera(L.)Vent.
