| Abstract: | Nine xanthones, nigrolineaxanthones A-I, together with nine known xanthones, were isolated from the crude methanol extract of the stem bark of Garcinia nigrolineata; two of which have previously been reported as synthetic xanthones. The structures were elucidated by analysis of spectroscopic data, especially using 1D and 2D NMR spectroscopic data. |
| Keywords: | Garcinia nigrolineata Guttiferae Trioxygenated and tetraoxygenated xanthones |
