Four new khayanolide-type limonoids with a 2-carbonyl group, named krishnolides A-D (1-4), were isolated from the seeds of an Indian mangrove, Xylocarpus moluccensis, collected in the mangrove swamp of Krishna estuary, Andhra Pradesh. The relative and absolute configurations of these compounds were established by HR-ESIMS, extensive NMR investigations, single-crystal X-ray diffraction analysis ...

THE TITLE COMPOUND [SYSTEMATIC NAME: (1S,3aS,4aR,4bS,5R,6aR,10aR,10bR,12aS)-1-(furan-3-yl)-5-hy-droxy-4b,7,7,10a,12a-penta-methyl-4b,5,6,6a,7,10a,10b,11,12,12a-deca-hydro-naphtho-[2,1-f]oxireno[2,3-d]isochromene-3,8(1H,3aH)-dione], C(26)H(32)O(6), which is a limonoid-type triterpene isolated from the seeds of X. moluccensis, crystallizes with three independent mol-ecules with very similar geome...

Coral bleaching has caused catastrophic changes to coral reef ecosystems around the world with profound ecological, social and economic repercussions. While its occurrence is predicted to increase in the future, we have little understanding of mechanisms that underlie changes in the fish community associated with coral degradation. The present study uses a field-based experiment to examine how ...

Otoliths are widely used to estimate the age and growth of fishes identify fish species. This information plays a vital role in fisheries management population dynamics studies. The about length otolith dimensions relationship Upeneus vittatus is lacking from Indian water. In this study, total 237 numbers individuals were collected October 2018 March 2019 left was studied since there no signifi...
