The humid tropics of Andaman and Nicobar islands represent one of the richest repositories of diverse biota in South.East Asia. They fall in Indo.Malayan realm of the biosphere of earth and belong to Island biogeographic zone. A number of 2,200 angiosperm species belonging to 84 families lies scattered, approximately 10% of which (223) are said to be endemics, 110 are considered as rare threatened. Over 50 plant species have collected only once and never again (eg. Symplocos oxyphylla in 1884 and Habenaria andamanica in 1891) and are known only from type collections. A large number of species have already been extinct; a few are on their last legs. Anthropogenic reasons seems to be the driving force behind such tragedy impairing natural ecological processes crucial to our well being and affecting the resilience of the systems. As such, biotic pressures in solitary small Islands are intense and in such habitat threatened species do not find alternate habitat or refuges, ultimately wiped out in the 'death traps' of Islands. The present article summarises the status of rare and endangered flowering plants with special reference to distribution patterns of endemics and extra Indian species in Bay Islands.

The Tin based herbal drug Vanga Parpamis extensively used for treating urino genital infections, Odema, Polydepsia and Dyspepsia effectively. There are no reports of physico chemical fingerprints for the tin based drug available. Proper characterization techniques are required for checking the quality of the commercial samples, in terms of the physical and chemical constitution to meet the expected criteria to support its use worldwide. Two popular commercial brands such drug were characterized and compared in terms of morphology, composition, crystal lattice, and oxidation state of the active metal. Physico-chemical fingerprints were generated for the samples using analytical techniques like Powder X ray crystallography, Scanning Electron Microscopy, Energy Dispersive X ray Analysis and Inductively Coupled Plasma Optical Emission Spectroscopy and Fourier Transformed Infra Red spectroscopy. It was found that the percentage of tin varied drastically in both brands along with a difference in the percentage composition of other elements and surface morphology which would have significant impact on the therapeutic efficacy and pharmacological activity of the drug samples. The current study appropriately substantiated the need for the use of modern analytical techniques in the establishment of quality and safety assurance of such potent drug.Keywords

Conductometric and spectrophotometric results suggested that Cr-Al Synthetic tainning materials formed micelle, which, was determined in aqueous as well as in different additive environments at different temperatures: The association constants (KA) for binding of Syntan with glycine was determined and the thermodynamic parameters of the process evaluated. While urea demicellised the system, NaCl enhanced micellisation. Considering micelles as a new phase, the free energy of transfer of Syntan from aqueous to glycine, urea and NaCl were found out. It was observed that the concentration of Syntan above cmc (preferably 5 to 10 times of cmc) was useful for tanning process. The aim for the preparation of this particular Syntan was to study its fixation for initiating high shrinkage temperature and light fastness.- Enhancing Phosphorus Utilization for Better Animal Production and Environment Sustainability

Phosphorus (P) is a key element in farm animal productivity and has a close relationship with calcium and vitamin D. Major part of P in feeds of plant origin is in the form of phytate which is not degraded in gut of monogastric animals and excreted in faeces contributing to environmental pollution. Studies have shown that exogenous supplementation of phytase enzyme to diet will improve phytate utilization. Genetic studies have proven the efficacy of low phytate grain with high available P content. Combination of phytase enzyme supplementation with use of low phytate feed ingredients is a practical and effective method of enhancing P utilization in monogastrics. Improved manure management to effectively recycle nutrients including P, needs further efforts to minimize pollution.Keywords
