摘要
以葡萄渣为原料,探讨超声波乙醇浸提法提取葡萄渣中总黄酮的实验条件,通过单因素实验与正交实验法确立了超声波提取工艺最佳条件为:乙醇浓度95%,超声波作用时间90 min,料液比1∶50(g∶mL),温度为60℃,提取次数2次,此时可获得较高的黄酮含量78.12mg/g。
Extraction of total flavonoids from grape residues by supersonic method were discussed. The quantity of total flavonoids extracted was determined. Optimum Conditions of extraction were determined by orthogonal method： the ratio of material over solvent is 1 ： 40 using 95% ethanol as solvent, and the extracting time is about 90min at the temperature of 60℃ by 2 times. The content of total flavonoids was up to 78.12mg/g.
