Xanthones and benzophenones from the stems of Garcinia multiflora.
J Nat Prod. 2003 Aug; 66(8):1070-3.JN

Abstract

Two new xanthone derivatives, garcinianones A (1) and B (2), two new benzophenone derivatives, 4,6,4'-trihydroxy-2,3'-dimethoxy-3-prenylbenzophenone (3) and 4,6,3',4'-tetrahydroxy-2-methoxybenzophenone (4), and a new inseparable mixture of (1E,22Z)-1,22-diferuloyloxydocosane and (1E,24Z)-1,24-diferuloyloxyteracosane (5), together with the previously known 3,8-dihydroxy-2,4,6-trimethoxyxanthone, 6,3'-dihydroxy-2,4-dimethoxybenzophenone, maclurin (6), 2,4,6,3'-tetrahydroxybenzophenone (7), and naringenin, were isolated from the stems of Garcinia multiflora. The structures of 1-5 were elucidated by extensive analysis of their spectral data. Compounds were evaluated in the brine shrimp lethality test and in the DPPH antioxidant assay.
