Tóm tắt

AbstractTwo 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.
