[Chemical constituents from the aerial part of Stauntonia obovatifoliola Hayata subsp. urophylla].

OBJECTIVE: To study the chemical constituents of the aerial part of Stauntonia obovatifoliola. METHODS: The chemical constituents of ethyl acetate fraction were isolated and purified by several chromatography. Their structures were elucidated by their physiochemical properties and spectral methods. RESULTS: Six known compounds were isolated and identified as lupeone(1), lupeol(2), stigmasterol(3),3beta-O-acetyloleanolic acid(4), resinone(5) and daucosterol(6). CONCLUSION: Compounds 1-6 are isolated from this plant for the first time.
