摘　　要：本文研究对比乙醇浸提和超声辅助提取两种方法提取梅州金柚柚籽中的总黄酮,对提取得率和提取工艺进行比较,超声辅助提取法较传统乙醇浸提法提取时间减少,提取得率上升。采用单因素试验初步筛选超声辅助提取工艺条件为:乙醇浓度70%,液料比20,超声功率80 W,提取时间2 h。有一定的自由基DPPH的清除效果和抗氧化活性。This paper studied the extracting of flavonoids from Meizhou Jinyou seed by the method of extraction and ultrasound-assisted extraction(UAE).UAE Compared with traditional ethanol extraction,UAE performed further extraction rate and shorter extraction time.The single factor experiment obtains the extract optimum condition is:ethanol density 50%,material/water ratio 1∶20,extraction power 70 W and extract time 2 h.The flavonoids from Jinyu seed had activity,which is close to the ascorbic acid,of scavenging DPPH radicals.
