Abstract:
Objective: To establish the quality control method for ephedrine in Herba Ephedrae and its preparation Zhisoulixiao Tablets (Herba Ephedrae, Pericarpium Papaveris, Semen Armeniacae Amrum, Radix Glycyrrhizae, Gypsum Fibrosum, Semen Lepidii, Semen Raphani, etc.) and Zhisoulixiao Capsules. Methods:Ephedrine hydrochloride contents in Herba Ephedrae and its preparation Zhisoulixiao Tablets and Zhisoulixiao Capsules were determined by TLC scanning with a mixture of chloroform ethyl acetate methanol water(13∶40∶22∶10)as a developer and single wavelength reflection sawtooth scanning. Results: The methodological study showed that a good linear correlation in the range from 0.29112?g to 1.4556?g of the ephedrine hydrochloride applied. The average recovery of ephedrine hydrochloride in Herba Ephedrae, Zhisoulixiao Tablets and Zhisoulixiao Capsules was 78.74%( n=5 ),99.46%( n=5) and 99.14%( n=5) ,respectively. Conclusion: The method established is simple,accurate with good reproducible and high precision.The method can be used for the quality control of Herba Ephedrae and its preparation
