目的建立龙船花根药材的质量标准。方法描述龙船花根药材性状及显微鉴别特征,制订薄层色谱鉴别方法;测定5批样品的水分、总灰分、酸不溶性灰分及浸出物含量以制定相应项目的合理限度。结果性状及鉴别方法专属性强,5批样品的水分、总灰分、酸不溶性灰分及浸出物的平均值为7.6%,2.8%,0.3%及18.0%。结论研究拟定的质量标准方法简便、准确,专属性强,可用于龙船花药材的质量控制。
Objective To establish the quality standard of dragon boat root medicine. Methods The characters and microscopic identification of the medicinal materials of Phalaenopsis longiflorum were described, and the identification method of TLC was established. The water, total ash, acid-insoluble ash and extract contents of 5 batches of samples were determined to set reasonable limits for the corresponding projects. The results showed that the traits and identification methods were highly specific. The average values of moisture, total ash, acid-insoluble ash and extractives of five batches of samples were 7.6%, 2.8%, 0.3% and 18.0%. Conclusion The proposed method of quality standard is simple, accurate and specific. It can be used for the quality control of Longhua anthers.
