摘要
采用凝胶型阴离子交换树脂纯化从女贞子果皮中提取的齐墩果酸粗品,通过单因素实验、正交实验优化了纯化工艺条件。确定最优纯化工艺条件为:树脂粒度100目、吸附和洗脱温度30℃、洗脱液乙醇体积分数80%,在此工艺条件下,所得齐墩果酸含量大于98%、回收率大于96%。
The crude oleanolic acid from the peel of Ligustrum lucidum Ait was purified using a gel-type anion exchange resins,and the purified conditions were optimized by a single factor experiment and orthogonal experiment. The optimal conditions were as following：the particle size of resin of 100 meshes,the adsorption and elution temperature of 30 ℃, and the ethanol volume fraction of 80%. The content and yield of oleanolic acid were over 98% and 96% ,respectively.
