title: Triterpenes and xanthones from the stem bark of Garcinia tetralata.
abstract: A new compound, 3β,18,19β-trihydroxylupane, was isolated from Garcinia tetralata, along with five known compounds, garcinexanthone B, morolic acid acetate, toxyloxanthone A, 6,11-dihydroxy-2,2-dimethylpyrano[3,2-c]xanthen-7(2H)-one, and 1,4-dihydroxy-5,6-dimethoxy-xanthone. The structure of the new compound was established by extensive spectroscopic techniques.
