【摘要】 本文建立了紫外谱线组法鉴别地钱、拳卷地钱和粗裂地钱的方法。通过这三种药材的石油醚、氯仿、乙醇和水提取液的紫外谱线比较,发现地钱、拳卷地钱和粗裂地钱的紫外谱线图、最大吸收峰数目及峰位值具有明显差异。该法简单、准确,可用来鉴别地钱、拳卷地钱和粗裂地钱的原药材。更多还原

【Abstract】 The discrimination of Marchantia polymorpha,Marchantia convoluta and Marchantia paleacea was succeeded by Ultraviolet Absorption Spectra Lines Group (UASLG).The UV spectra of the solutions extracted by four different kinds of solvents (water, chloroform, ethanol and petroleum ). The UV spectra of the three herbals gave different maximum absorption peaks both in number and intensities. The method was simple and accurate and can be used to distinguish one from others.更多还原
