BACKGROUND Gorgonians and other octocorals are known to possess a huge array of secondary metabolites in which sterols are the major group of secondary metabolites apart from sesquiterpenes and diterpenes, and the bioactive metabolites could show marked biomedical potential for future drug discovery. OBJECTIVE This study was intended for the isolation and(More)
A mobile adhoc network is an independent collection of mobile nodes without having the fixed infrastructure. In the mobile adhoc networks, because of the high mobility of the nodes there is frequent link breakage that causes frequent path failure and route discoveries. A mobile node instinctively rebroadcasts the route request packets and it causes the(More)
The composition of the lipophilic extract from Hydrilla verticillata, the common aquatic weed collected from Sasthamkotta Lake, the largest freshwater lake in Kerala, south of the west coast of India, was investigated. The lake is a designated wetland of international importance under the Ramsar Convention since 2002. GC-MS study of the unsaponifiable(More)
The steroidal composition of the marine sponge Axinella carteri, collected from Lakshadweep archipelago in the Arabian Sea was found to be a prolific source for a variety of rare steroids. The GC–MS study afforded us with the occurrence of 8 steroids belonging to four different types of nucleus, including the unique occurrence of an unconventional steroid(More)
Concentrations and distributions of trace metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in surficial sediments of the Cochin backwaters were studied during both monsoon and pre-monsoon periods. Spatial variations were in accordance with textural charaterstics and organic matter content. A principal component analysis distinguished three zones with(More)
