母草及泥花草的生药学研究

Pharmacognostical study on Lindernia crustacea and Lindernia antipoda

目的对玄参科母草属植物母草及泥花草进行生药学研究,为该药用资源的开发利用提供依据。方法采用性状鉴别、显微鉴别、理化鉴别的方法。结果明确了2种植物的性状特征和粉末、横切面的特征,初步判断两种植物中均含环烯醚萜苷类成分。结论该鉴定方法可靠,可作为2种植物的鉴定依据。

Objective To identify two Lindernia species,L.crustacea and L.antipoda histologically and morphologically.Methods Morphological and microstructural characters were described,and physical and chemical methods were established.Results Collenchyma was found in the stems angular of L.crustacea,of which the cells were vertically elongated,and large air cavities were distributed in the cortical aerenchyma.While in the cortex of L.antipoda,there were many fiber bundles,and little aerenchyma or large air-cavity.Iridoids can be detected in both the species.Conclusion The method is easy and reliable,suitable for the quality control of these two plants.
