摘　　要：以仙人掌为原料,用甲醇提取仙人掌中黄酮类化合物。考察了料液比(仙人掌干粉质量与提取剂体积之比,g/m L)、提取温度、提取时间和甲醇浓度对仙人掌中黄酮的提取的影响,通过正交试验确定了最佳提取条件:料液比为1∶30(g/m L),提取温度为60℃,提取时间为3.5 h,甲醇浓度为95%。在该工艺条件下黄酮的提取率为0.741%。In this thesis, cactus as raw material, methanol was used by refluxing extraction to extract flavonoids. The ratio of material to liquid （the ratio of cactus powder quality and the extractant volume, g/mL）, extraction temperature, extraction time and potency of extraction agent were inspected to influence on the extraction yield of cactus flavonoids. Through the orthogonal experiment , the optimum extraction conditions were abtained as follows：the ratio of material to liquid was 1∶30 （g/mL）, extraction temperature was 60℃, extracting time was 3.5 h and content of methanol was 95 %. Under this condition , the extraction yield of flavonoids from cactus was 0.741%.
