    Author: Xu X, Zhang Y, Yang J, Zhu Z.
    Journal: Zhongguo Zhong Yao Za Zhi; 1998 Dec; 23(12):733-4, 764. PubMed ID: 12242822.
    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, 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.
