目的建立丝瓜络三种不同炮制品(丝瓜络(块)、炒丝瓜络、丝瓜络炭)的质量标准。方法分别考察不同来源样品的性状、水分、灰分、酸不溶灰分等项目、建立TLC鉴别方法。结果 14批样品各项指标有一定差异,新建立的TLC鉴别方法斑点清晰,专属性好。结论药材经不同炮制方法炮制后各项理化指标发生了一定的变化,为制定饮片标准提供了实验依据。
Objective To establish the quality standards of three kinds of processed products of loofah (loofah (block), fried loofah, loofah charcoal). Methods The characters, moisture, ash and acid-insoluble ash of different samples were investigated separately, and TLC identification method was established. Results There were some differences among the 14 batches of samples. The newly established TLC identification method had clear spots and good specificity. Conclusion The physicochemical properties of the medicinal materials processed by different processing methods have undergone some changes, providing the experimental basis for the development of the standard of the decoction piece.
