TL;DR: Ten new limonoids, hainangranatumins A-J, and 25 known compounds were isolated from seeds of a Chinese mangrove, Xylocarpus granatum, collected on Hainan Island, for the first report of X-ray crystallographic structures of 9,10-seco-mexicanolides with a flexible C2-C30-C8 linkage.
Abstract: Ten new limonoids, hainangranatumins A-J (1-10), and 25 known compounds were isolated from seeds of a Chinese mangrove, Xylocarpus granatum, collected on Hainan Island. Hainangranatumins A-E (1-5) and I and J (9 and 10) are 9,10-seco-mexicanolides, whereas hainangranatumin F (6) is a limonoid possessing an 8 alpha,30 alpha-epoxy ring and a C1-C29 oxygen bridge. Hainangranatumin G (7) is a limonoid with a central pyridine ring, and hainangranatumin H (8) is a phragmalin 1,8,9-ortho ester. The relative configurations of hainangranatumins A and B were established by means of single-crystal X-ray diffraction analysis, and their absolute configurations were assigned on the basis of the specific rotation of the free acids obtained from alkaline hydrolysis. This is the first report of X-ray crystallographic structures of 9,10-seco-mexicanolides with a flexible C-2-C-30-C-8 linkage. Hainangranatumins I and J (9 and 10), unusual 9,10-seco-mexicanolides with a C-9-C-30 linkage, are proposed to be artifacts derived from hainangranatumin C and xylomexicanin A, respectively.

TL;DR: Seven new limonoids (1-7) were isolated from seeds of an Indian mangrove (Xylocarpus granatum) collected from the wetlands of Krishna estuary, Andhra Pradesh, on the basis of spectroscopic data.
Abstract: Seven new limonoids (1-7), named granatumins A-G, were isolated from seeds of an Indian mangrove (Xylocarpus granatum) collected from the wetlands of Krishna estuary, Andhra Pradesh. The known compounds khayasin T, tigloylseneganolide A, 6-deoxyswietenine, swietemahonolide, febrifugin A, gedunin, xylogranatinin, phaseic acid, (2R,3R)-3,4',5,7-tetrahydroxyflavanone, and (E)-4-hydroxycinnamic acid were also isolated. The structures were established on the basis of spectroscopic data. Granatumins A and B are mexicanolides with endo-conjugated Delta(8.30) and Delta(14.15) double bonds, and granatumins F and G are polyhydroxylated phragmalins found previously in plants of the Meliaceae. Khayasin T exhibited moderate insecticidal activity against fifth instar larvae of Brontispa longissima (Gestro) at a concentration of 20 mg/L.

TL;DR: Five new limonoids, including andhraxylocarpins A and B (1 and 2) which contain a 9-oxa-tricyclo[3.3.1.1(3, 6)]decane-9-one scaffold, were isolated from the seeds of two true mangroves that were collected in the estuaries of Andhra Pradesh, India.
Abstract: Five new limonoids, including andhraxylocarpins A and B (1 and 2) which contain a 9-oxa-tricyclo[3.3.2.17,?10]undecane-2-ene motif, andhraxylocarpins C and D (3 and 4), which contain a (Z)-bicyclo[5.2.1]dec-3-en-8-one substructure, and andhraxylocarpin E (5), which contains a tricyclo[3.3.1.13,?6]decane-9-one scaffold, were isolated from the seeds of two true mangroves, Xylocarpus granatum and Xylocarpus moluccensis, that were collected in the estuaries of Andhra Pradesh, India. The absolute configurations of these compounds were determined by extensive NMR investigations, single-crystal X-ray diffraction analysis, and by circular dichroism and optical rotatory dispersion spectroscopy, in combination with quantum-chemical calculations. The pronounced structural diversity of limonoids from these mangroves might originate from environmental factors.

Abstract: Covering: 2010. Previous review: Nat. Prod. Rep., 2011, 28, 196. This review covers the literature published in 2010 for marine natural products, with 895 citations (590 for the period January to December 2010) referring to compounds isolated from marine microorganisms and phytoplankton, green, brown and red algae, sponges, cnidarians, bryozoans, molluscs, tunicates, echinoderms, mangroves and other intertidal plants and microorganisms. The emphasis is on new compounds (1003 for 2010), together with the relevant biological activities, source organisms and country of origin. Biosynthetic studies, first syntheses, and syntheses that lead to the revision of structures or stereochemistries, have been included.
