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。
This paper establishes a method of ultraviolet spectroscopy to identify the ways of money, money and money. Through comparison of ultraviolet spectrums of the petroleum ether, chloroform, ethanol and water extracts of these three medicinal materials, it was found that the ultraviolet spectrum maps, the maximum number of absorption peaks, and the peak value of the diurnal, the marsupial, and the cracked ground money have obvious difference. The method is simple and accurate and can be used to identify the original medicines of the land money, the boxing money and the crude money.
