Study on Extraction of Dioscin from D.zingiberensis
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.
