Study on Extraction of Dioscin from D.zingiberensis

Article Preview

Abstract:

The effects of extraction conditions on Extraction of Dioscin from D.zingiberensis was studied in this paper. It was shown that when the ultrasonic frequency was 35.74KHz, solid-liquid ratio(D.zingiberensis:ethanol)was 1:10, ethanol volume fraction was 75%, and extracted for 30 minutes and for 3 times, the extraction rate of dioscin from D.zingiberensis reached the highest. The method of ultrasonic-assisted ethanol extraction can not only cut down extraction time, but also increase extraction yield.
