摘　　要：[目的]研究不同提取方法对女贞子中齐墩果酸提取率的影响。[方法]以女贞子为原料,优选微波辅助提取、超声波辅助提取和超临界萃取3种方法提取齐墩果酸的工艺条件,以齐墩果酸的提取率来比较3种方法的优劣。[结果]微波辅助提取法提取齐墩果酸的含量为1.100%(保留时间为4.116 min);超临界萃取法提取齐墩果酸含量为1.107%(保留时间为4.115 min);超声波辅助提取法提取齐墩果酸含量为1.291%(保留时间为4.107 min)。[结论]3种方法与常规溶剂浸提法比较均具有提取时间短、提取效率高、方法简便等特点,试验结果为女贞子中齐墩果酸不同提取要求提供了理论基础。[Objective] The aim was to study on the effects of different extraction methods on the extraction rate of oleanolic acid in LIGUSTRI LUCIDI FRUCTUS.[Method] Taking LIGUSTRI LUCIDI FRUCTUS as the material,the three extraction methods were compared according to the extraction rate of oleanolic acid,which were the microwave-assisted extraction,the ultrasonic-assisted extraction,and the supercritical fluid extraction.[Result] Content of oleanolic acid was 1.100%by the microwave-assisted extraction（retention time of 4.116 min）,1.107% by supercritical fluid extraction（retention time of 4.115 min）,and 1.291% by ultrasonic-assisted extraction（（retention time of 4.107 min）.[Conclusion] Compared with the conventional solvent extraction method,the three methods had the characteristics of short extraction time,high extraction yield,simple operating method and so on.The research results provided theoretical basis for the different extraction requirements of oleanolic acid in LIGUSTRI LUCIDI FRUCTUS.
