摘要: 采用分光光度法,研究影响荸荠中黄酮类化合物提取量的多种因素,并通过L9(34)正交试验设计优化出提取荸荠中黄酮类化合物的最佳工艺条件。结果表明,荸荠中总黄酮的含量为0.8621%,乙醇提取法的最适工艺参数是浸提剂乙醇浓度60%、提取温度70℃、料液比1:50、浸提时间3.5h。

Abstract: By spectrophotometric method,effects of some factors on extraction rate of flavaoids from water chestnut were studied. The orthogonal design of L9(34) was used to confirm the optimal technological parameters. The results showed that the content of total flavonoids in water chestnut is 0.8621%,and the optimum conditions of ethanol extraction are obtained as follows:extracting material with 50-times 60% ethalnol at 70℃ for 3 h.
