Isolation and structural elucidation of chemical constituents from the fruits of Morinda citrifolia Linn.
The fruits of Morinda citrifolia, Linn. afforded a new constituent, morinaphthalenone (1), and three known constituents, scopoletin (2), 1, 3-dimethoxy-anthraquinone (3) and 1, 2-dihydroxy-anthraquinone (4). The structures of these isolated compounds were determined by spectroscopic methods, including 1D- and 2D-NMR (COSY-45, HMQC, HMBC) techniques, as well as by comparison with published values.
