title: New constituents from stems of Artabotrys uncinatus.
abstract: Two new compounds, 4,5-dioxoartacinatine (1) and 24-methylenelanosta-7,9(11)-diene-3-one (2), together with thirty known compounds were isolated and characterized from the stems of Artabotrys uncinatus. Structures of the new compounds were determined by spectral analysis.
