Abstract:
One new limonoid of the phragmalin type (1) named Swietenine J with nine known compounds methyl-6-β-hydroxy angolensate (2), 1-O-acetylkhayanolide A(3), Khayanolide E (4), Khayalactone (5), Khayanone (6), 1-O-Acetylkhayanolide B (7), 1-O-Deacetylkhayanolide E (8), Khayanolide A (9), Khayanolide B (10) were isolated from Swietenia macrophylla. The structure of 1 was elucidated on the basis of 1D and 2D- NMR spectroscopic analysis.
