【摘要】 用正交实验探讨沙棘果渣中黄酮类化合物的最佳提取工艺。实验结果为 :在 80℃的条件下用 70 %乙醇回流提取 3次 ,每次 1h ,料液比为 1∶6(W/V)。在此条件下 ,黄酮类化合物的得率达 94 6%。更多还原

【Abstract】 In this paper the optimum extracting conditions of hipplhae flavonoids were investigated by orthogonal experiment.The results showed under the conditions of 80℃,1∶6(W/V),70% ethanol,extracting 3 times and 1 h for each time,the extraction ratio of flavonoids was 94.6%更多还原
