挂金灯药材质量标准研究

Study on Quality Standard of Physalis angulatae Fructus

目的：建立和完善挂金灯药材的质量标准。方法：采用性状鉴别、显微鉴别及薄层色谱法对挂金灯药材进行定性鉴别;同时根据2010年版《中华人民共和国药典》规定的方法对其水分、总灰分、酸不溶性灰分及浸出物进行测定。结果：挂金灯药材显微特征、薄层色谱斑点均清晰明显;5批挂金灯样品的水分测定结果为7.9%-10.1%,总灰分为8.8%-14.6%,酸不溶性灰分为0.3%-3.8%,浸出物测定结果为11.9%-17.4%。结论：本研究为挂金灯药材质量标准的提高提供参考。

Objective ： To establish and revise the quality standard of Physalis Angulatae Fructus. Methods ： Physalis Angulatae Fructus was identified by macroscopic, microscopic and TLC methods. And referring to Chinese Pharmacopoeia of 2010 edition, water content, total ash, acid-insoluble ash and extract were also determined. Results： The microscopic characteristics and the spots of TLC were clear and evident. The water content, total ash, acid-insoluble ash and extract of 5 Physalis Angulatae Fructus samples varied in the ranges of 7.9%-10. 1%, 8.8%-14.6%, 0.3%-3.8% and 11.9%- 17.4%, respectively. Conclusion： The established quality control method is comprehensive and controllable, which can be used to improve the quality standard of Physalis Angulatae Fructus.
