Abstract

Two new xanthones, 1,5,6-trihydroxy-6′,6′-dimethyl-2H-pyrano(2′,3′:3,4)-2-(3-methylbut-2-enyl)xanthone (1) and 1,6,7-trihydroxy-6′,6′-dimethyl-2H-pyrano(2′,3′:3,2)-4-(3-methylbut-2-enyl)xanthone (2), have been isolated from the stem bark of Garcinia lancilimba (Guttiferae), together with six known xanthones. Their structures were identified on the basis of extensive spectral evidence including detailed 2D NMR and HR-MS data. Two new compounds showed moderate inhibitory effect on human breast cancer MDA-MB-435S cell line.
