An on-the-spot method for rapid determination of quality of artemisiae annuae,herba / 重庆医科大学学报

Objective:To establish a simple,fast,exact and sensitive method to determine the quality of arteannuin on the spot.Methods:In contrast to the results based on HPLC in the aid of soxhlet extraction,an on-the-spot determination of Artemisinin by UV aided by ul-trasonic extraction was proposed.Results:The content of Artemisinin extracted with on-the-spot method for rapid determination is com-puted by equation:MRD(mg.g-1)=(A?V?2.2984)(/As?3)+1.2067.Conclusion:This method with ultrasonic extraction of artean-nuin and UV determination simplified the procedure and saved work time.It proved to be an satisfactory method for determination of arteannuin.
