Two new mexicanolides, named granatumins H and I ( 1 and 2 , resp.), and two phragmalins, named granatumins J and K ( 3 and 4 , resp.), were isolated from the seeds of an Indian mangrove, Xylocarpus moluccensis , collected from the swamps of Krishna estuary, Andhra Pradesh. The structures of these limonoids were established on the basis of spectroscopic data. Granatumin J ( 3 ) is a highly oxidized phragmalin with five AcO groups, whereas granatumin K ( 4 ) is the first phragmalin found in nature with conjugated C(8)C(30) and C(14)C(15) bonds.
