中文摘要: 采用螯合剂辅助乙醇浸提法提取猕猴桃果皮中的黄酮，以黄酮得率为考察指标，采用单因素和正交试验探讨乙醇浓度、料液比、提取时间、提取温度、螯合剂（-SH）六偏磷酸钠添加量对黄酮得率的影响。试验结果表明，最佳提取工艺为：乙醇浓度60%，料液比1∶20（g/mL），提取时间 70 min，提取温度80℃，螯合剂（-SH）六偏磷酸钠添加量0.6%，在此条件下猕猴桃皮黄酮的得率为1.518%。
Abstract:Ethanol extraction was used associated with a chelator to extract flavonoids from kiwifruit peels，taking the yield of flavonoids as review indicator.The factors of flavonoids extraction including ethanol concentration，solid-liquid ratio，extraction time and temprature，the addition of sodium hexametaphosphate（-SH）were studied by single factor tests and orthogonal tests.The results showed that the optimum condition was that the ethanol concentration of 60%，solid-liquid radio of 1∶20（g/mL），extracting time of 70 min，extracting temperature at 80℃，the addition of sodium hexametaphosphate（-SH）of 0.6 %.Under these conditions，the yield of flavonoids was 1.518%.
