Phloroglucinols, depsidones and xanthones from the twigs of Garcinia parvifolia.[Reference: WebLink]

METHODS AND RESULTS:
Seven phloroglucinols, named parvifoliols A–G (1–7), two depsidones, named parvifolidones A, B (8, 9), and three xanthones, named parvifolixanthone A, Parvifolixanthone B, parvifolixanthone 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.
CONCLUSIONS:
Their structures were proposed on the basis of spectroscopic data. The antibacterial and antioxidation activities were evaluated.
