Isolation and structure determination of two new constituents from the fruits of Morinda citrifolia Linn.
Studies on the chemical constituents of the fruits of Morinda citrifolia Linn. have led to the isolation of two new compounds, morinaphthalene (=1,3,6,7-tetrahydroxy-2-hydroxymethyl-1,2,3,4-tetrahydronaphthalene, (1); and morindafurone (=5-hydroxy-1,10b-dihydro-6H-anthra [1,9-bc] furan-6-one, (2); as well as two known constituents, 1,8-dihydroxy-6-methoxy-3-methyl-9-anthrone (3) and 2,4-dimethoxy-9-anthrone (4). Their structures were elucidated by spectral analysis including 2D NMR techniques.
