摘要:研究了超声条件下提取杜仲叶中绿原酸的溶剂效应.分别采用水、甲醇、乙醇、乙酸乙酯、丙酮等不同极性的溶剂进行提取,考察了溶剂配比、溶剂pH值等因素对绿原酸提取率的影响.结果表明:用甲醇提取时,绿原酸提取率最高,超声助提杜仲叶中绿原酸的最佳溶剂条件是pH值为4.5的70%的甲醇水溶液.

关键词: 超声助提, 杜仲叶, 绿原酸, 溶剂效应, 高效液相色谱

Abstract: Solvent effect on ultrasonically assisted extraction of chlorogenic acid from the leaves of Eucommia ulmodies was investigated.Extraction was carried out by using water,methanol,ethyl alcohol,ethyl acetate and acetone as solvent,respectively.The influence of the ratios and pH values of mixed solvent on the extraction efficiency of chlorogenic acid was evaluated.Results indicated that the extraction efficiency obtained using methanol as solvent was the highest and the optimized solvent for the ultrasonically assisted extraction of chlorogenic acid was 70% methanol water solution with a pH value of 4.5.

Key words: Ultrasonically assisted extraction, Eucommia ulmodies leaves, Chlorogenica acid, Solvent effect, HPLC
