Chem Pharm Bull (Tokyo). 2005 Jul;53(7):850-852. | Antibacterial caged-tetraprenylated xanthones from the fruits of Garcinia hanburyi[Pubmed: 15997152] | A new caged-tetraprenylated xanthone, hanburinone (1), was isolated from the fresh fruits of Garcinia hanburyi together with four known caged-tetraprenylated xanthones; isomoreollin B (2), morellin (3), Moreollic acid (4) and morellic acid (5). Their structures were elucidated by analysis of spectroscopic data and comparison of the NMR data with those reported previously. Compounds 4 and 5 showed moderately antibacterial activity against methicillin-resistant Staphylococcus aureus with a MIC value of 25 microg/ml. | Phytochemistry . 1996 Feb;41(3):815-820. | Cytotoxic xanthones from Garcinia hanburyi[Pubmed: 8835458] | Eleven novel cytotoxic xanthones, gambogin, morellin dimethyl acetal, isomoreollin B, Moreollic acid, gambogenic acid, gambogenin, isogambogenin, desoxygambogenin, gambogenin dimethyl acetal, gambogellic acid and hanburin were isolated together with four known xanthones, gambogic acid, isomorellin, morellic acid and desoxymorellin, from the dry latex of Garcinia hanburyi. The structures were elucidated by a detailed spectroscopic analysis. |
