title: Xanthones and triterpenoids from the bark of Garcinia vilersiana.
abstract: The hexane extract of the bark of Garcinia vilersiana from Vietnam contained four triterpenoids (olean-12-ene-3beta,11alpha-diol, lupeol, beta-amyrin and oleanolic acid), and six xanthones (globuxanthone, subelliptenone H, subelliptenone B, 12b-hydroxy-des-D-garcigerrin A, 1-O-methylglobuxanthone and symphoxanthone). The structure of 1-O-methylglobuxanthone, the only novel compound, was determined using 1D and 2D NMR techniques and by correlation with globuxanthone.
