摘要
采用正交法研究了乙醇溶剂提取仙人掌中黄酮类物质的工艺条件.利用单因素试验,确定影响黄酮提取效果的4个因素:乙醇浓度、提取温度、提取时间和料液比的较优水平,用正交设计试验优化提取工艺条件.结果表明,最佳提取条件为乙醇浓度(V/V)90%、料液比20/1、温度55℃、时间1 h.
Extraction conditions of flavonoids from cactus using orthogonal design was studied. The suitable levels of ethanol concentration, extraction temperature, extraction time and ratio of material to solvent were determined using one-factor experiment, and orthogonal design was used to optimize the extraction condition. The results show that the optimum conditions were 90 % ethanol, ratio of material to solvent 20/1, temperature 55 ℃ and extraction time 1 h.
