The optimum process of extracting corosolic acid, an anti-diabetic component from Eriobotrya japonica leaves was(studied).

A method was developed for the determination of corosolic acid in Eriobotrya japonica leaves by reversed-phase high performance liquid chromatography(RP-HPLC).

Results The compounds were identified as: Maslinic acid(Ⅰ),Corosolic acid(Ⅱ),oleanlic acid(Ⅲ),ursolic acid(Ⅳ).
