Parvifoliquinone (1) was isolated from the leaves of Garcinia parvifolia together with six known compounds: parvifoliols B (2), C (3), E (4), garcidepsidone B (5), nigrolineaisoflavone A (6), and mangostinone (7). The structures were elucidated by spectral analyses. Their antibacterial activity against methicillin-resistant Staphylococcus aureus was evaluated.
Seven phloroglucinols, named parvifoliols A–G (1–7), two depsidones, named parvifolidones A, B (8, 9), and three xanthones, named parvifolixanthones A–C (10–12), were isolated from the twigs of Garcinia parvifolia along with seven known compounds: garcidepsidone B, mangostinone, rubraxanthone, dulxanthone D, 1,3,5,6-tetrahydroxyxanthone, norathyriol, and (2E,6E,10E)-(+)-4β-hydroxy-3-methyl-5β-(3,7,11,15-tetramethylhexadeca-2,6,10,14-tetraenyl)cyclohex-2-en-1-one...
