5种卷柏科药材的显微与薄层色谱鉴定

Study on the identification of the five medicinal herbs from Selaginellaceae by microscopy and TLC

目的:建立5种卷柏科药材(卷柏、垫状卷柏、江南卷柏、翠云草、薄叶卷柏)的显微与薄层色谱鉴定方法。方法:对茎横切面进行显微观察及对全草进行薄层色谱研究,通过比较,确立各种药材的鉴别特征。结果:5种药材均有稳定的显微特征及各自的薄层色谱。结论:研究结果为5种卷柏类药材的应用提供了鉴别依据;并说明比较研究是中药鉴定学科中不可忽视的基本方法。

OBJECTIVE To establish methods tor identification of the five medicinal plants, Selaginella tamariseima, S. pulvinate, S. maellendorffii, S. uncinata and S. delieatula from Selaginellaceae by microscopy and TLC. METHODS Mieroseopic structures of the stems of the five plant species were studied, TLC of the live medieinal herbs were studied too, The features used for distinguisbing them were found through the comparative analysis, RESULTS Stable microscopic features and unique TLC resuhs of the medicinal herbs were found, CONCLUSION The resuhs provide basis for identification of the, five medicinal herbs. The comparative analysis is a basic method which should nol be neglected in identification of Chinese, medicinal herbs.
