Abstract:Objective:To investigate the chemical constituents of Aralia subcapitata.Method:The methanol extract of A. subcapitata was separated by repeated column chromatography,and the compounds were identified on the basis of spectroscopic analysis(IR,EI-MS,HNMR and13 CNMR)and physicochemical properties.Result:Four compounds were isolated from the root bark of A. subcapitata.Their structures were identified as 3β-hydroxy-oleana-11,13(18)-dien-28-oic acid(I),3-oxo-oleana-12-en-28-oic(Ⅱ),oleanolic acid(Ⅲ)and daucosterol(Ⅳ).Conclusion:All these compounds were isolated from this plant for the first time.Among them,compounds Ⅰand Ⅱ were obtained for the first time from Aralia.
