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, 1HNMR and 13CNMR) and physicochemical properties.
Result: Four compounds were isolated from the root bark of A. subcapitata. Their structures were identified as 3 beta-hydroxy-oleana-11, 13(18)-dien-28-oic acid(I), 3-oxo-oleana-12-en-28-oic acid (II), oleanolic acid(III) and daucosterol(IV).
Conclusion: All these compounds were isolated from this plant for the first time. Among them, compounds I and II were obtained for the first time from Aralia.
