【摘要】 [Objective]To select the optimal extraction technology of ursolic acid in Ligustrum lucidum Ait. . [Method]Taking 5% vanillin and perchloric acid as the color reagents,ursolic acid was extracted from L. lucidum by cellulose method. The optimal color condition was determined by orthogonal test; and the content of ursolic acid was determined at 550 nm. [Conclusion]The optimal color condition was 0. 3 ml 5% vanillin,1. 0 ml perchloric acid under 60 ℃. Under this condition,the extraction rate of ursolic acid in L. vicaryi flower was 2. 037%. [Conclusion] Results of orthogonal test showed that the content of ursolic acid was the highest in the fruits of L. vicaryi.
