Abstract
|
|
|
|
In result of analysis for the content determination of ursolic acid(UA) and oleanolic acid(OA) in extract of Eriobotryae folium using HPLC with UV detector, UA in chloroform extract of Moo-mok variety was showed highest content(2.7843 mg/g). And OA in ethyl acetate extract of Dae-bang variety was showed highest content(0.5898 mg/g). These result suggest that direct extraction using organic solvent(chloroform or ethyl acetate) was useful method for rapid quantitative analysis of UA and OA without preprocessing such as drying or fractionation.
