The phytochemical investigation of the methanol extract of bark of Garcinia oblongifolia yielded a new xanthone derivative 1,3,8-trihydroxy-6’,6’-dimethylpyrano (2’,3’:5,6) xanthone (5) along with 8 known compounds, including 1,2,5-trihydroxy-6-methoxyxanthone (1), 1,3,6,7-tetrahydroxy-2,5-bis… Click to show full abstract
The phytochemical investigation of the methanol extract of bark of Garcinia oblongifolia yielded a new xanthone derivative 1,3,8-trihydroxy-6’,6’-dimethylpyrano (2’,3’:5,6) xanthone (5) along with 8 known compounds, including 1,2,5-trihydroxy-6-methoxyxanthone (1), 1,3,6,7-tetrahydroxy-2,5-bis (3-methylbut-2-enyl) xanthen-9-one (2), xanthone V1 (3), isojacareubin (4), methyl protocatechuate (6), isoxanthochymol (7), euxanthone (8), and protocatechuic acid (9). The structures of these compounds were verified based on extensive spectroscopic data analysis as well as comparison with the literature data.
