چکیده
Two new mexicanolides, named xylomexicanolides A and B, were isolated from the seeds of an Indian mangrove, Xylocarpus moluccensis, together with four known limonoids, khayasin, angolensic acid methyl ester, khayasin T, and 2'S-methylbutanoylproceranolide. The structures of these limonoids were established on the basis of spectroscopic data. The (13)C-NMR data of khayasin were reported for the first time. Khayasin was found to exhibit marked insecticidal activity against the fifth instar larvae of Brontispa longissima (GESTRO) at a concentration of 10 mg/l.

متن کاملProtoxylogranatin B, a Key Biosynthetic Intermediate from Xylocarpus granatum: Suggesting an Oxidative Cleavage Biogenetic Pathway to Limonoid
Protoxylogranatin B, a new protolimonoid identified from the seeds of a Chinese mangrove, Xylocarpus granatum, was proposed as the key biosynthetic intermediate. Its structure was established on the basis of spectroscopic techniques, including 1 H– 1 H COSY, HSQC, HMBC and NOESY spectra. The finding of this compound suggested an oxidative cleavage biogenetic pathway from protolimonoid to limonoid.
