| Abstract: | Taking the ampelopsis as the raw material,under the condition that ethanol soaks to prepare the processing,taking water as the associated extract dihydromyrictin(MAE).The MAE conditions,such as the soaking time of ethanol,the duration of extraction,and the heating time,were all studied to obtain maximum extraction yield.The most suitable conditions for the extraction was that the soaking time of ethanol was 15 h,the duration of extraction was 1:8,and the heating time was 30 min.The extracting rate of MAE was 34.23% in this conditons. |
