摘要
采用对比分析的方法,研究了影响笃斯越桔叶中黄酮类化合物提取率的多种因素,并通过L9(34)正交试验设计优化出热回流法提取笃斯越桔叶中黄酮类化合物的最佳工艺条件:温度为80℃,料液比为1/50,乙醇浓度为80%,时间为25min。
Based on contrast analysis, some factors that affect extracting rate of flavanoids from Vaccinium uliginosum.L were studied. The orthogonal design of Lg（34）was used to select the optimal technological conditions for extracting flavanoids from leaves of Vaccinium uliginosum L .with the internal reflux method, and the optimal parameters were as follows： temperature 80 ℃, the ratio of 1/50, ratio of material to water 1：50, concentration of alcohol 80%, time 25min.
