[Studies on the chemical constituents of the fruit of Xylocarpus granatum].

OBJECTIVE

To study the chemical constituents of the fruit of Xylocarpus granatum.

METHODS

The chemical constituents were isolated by chromatographic methods and their structures were elucidated by NMR spectra and physicochemical properties.

RESULTS

Ten compounds were isolated from the fruit of Xylocarpus granatum and the structures of them were identified as spicatin (1), xyloccensin K(2), 6-acetoxycedrodorin (3), aurantiamide acetate (4), (+)-catechin (5), alpha-tocopherol (6), abscisic acid (7), daucosterol (8), 4-hydroxybenzoic acid (9) and ethyl 3,4-dihydroxybenzoate (10).

CONCLUSION

Compound 4 -10 are isolated from this plant for the first time.
