摘　　要： 用正交设计法,以水为溶剂,考察了提取温度、微波辐射时间及料液比3个因素,每个因素3个水平,选择L9(33)正交设计表,用HPLC法测定二氢杨梅素,并以其含量作为评价指标。结果表明:在提取温度为95℃,微波辐射时间为15 min,料液比为1:20时二氢杨梅素的提取率最高。 The optimum extracting condition of dihydromyricetin from ampelopsis was studied. The MAE conditions, such as the extraction solvent volume, extraction temperature, and the period of extraction, were all studied in the orthogonal test. The most suitable conditions for the extractions were as follows： the extracting temperature was 95 ℃, the extracting time was 15min, and the solid-liquld leaching ration was 1：20.
