摘　　要：为综合利用龙芽楤木资源.以龙芽楤木根皮和茎皮为供试材料,以齐墩果酸的含量为检测指标,用分光光度法在540nm处测吸光值进行含量测定,用醇提-酸碱处理法对龙芽楤木根皮和茎皮中齐墩果酸进行提取和纯化。结果,龙芽楤木根皮和茎皮中齐墩果酸含量分别为5.52%、2.28%.提取和纯化后得率分别为2.61%、0.21%。为龙芽楤木资源的综合利用提供参考依据。By measuring the content of Aralia elata root bark and stem bark oleanolic acid, provide the basis for the comprehensive utilization of resources of Aralia elata. In Aralia elata root bark and stem bark as material,in ethanol extract, using alcohol extract-acid treatment method and root bark of Aralia elata reflux bark extract,conduct impurity bleaching and refining to extract more pure oleanolic acid with activated carbon and ethanol. Results： The oleanolic acid content in the velamen and bark of Aralia elata was 5.52%,2.28%. purified. oleanolic acid yield was 2.61% 、0.21%.
