| Abstract: | AIM:To study the application of ultrasonic extraction in process of extracting diosgenin from Dioscorea zingiberensis C.H.Wright,and to evaluate its merits.METHODS:A new process of ethanol extracting and hydrochloric acid hydrolysis was provided to extraction diosgenin,and five different extraction methods were studied and compared,and the reaction mechanism was discussed.RESULTS:The ultrasonic extraction method was more efficient.Compared with the traditional water-hydrolylis,extraction rate was 15 percent higher,dosage of hydrochloric acid was registered 90 percent decrease,and the production was purer.CONCLUSION:The grinding pretreatment of Dioscorea zingiberensis is help to enhance the effects of ultrasonic extraction,the method has some advantages in efficiency,energy-saving and low pollution. |
