Syzygium caryophyllatum (L.) Alston is red listed as a threatened species according to International Union of Conservation of Nature and Natural Resources. The various phytochemicals present in the fruit of this plant were analysed using Liquid Chromatography Mass Spectroscopy (LCMS) and their bio activities were predicted using Prediction of Activity Spectra for Substances (PASS). Plants produce a variety of secondary metabolites that are not needed for the growth of plants but are essential for other uses such as protection, pollination etc. The results showed the presence of numerous phytochemicals such as terpenoids, carotenoids, alkaloids, carboxylic acids, and phenolic compounds such as flavanoids, other compounds such as coumarins, saponins, glycosides and sterols. The activity spectra of compounds were predicted using the chemical formula reveals that the compounds present in pulp and seed are active against numerous diseases. Many pharmaceutical industries use computer aided programs for the designing of new drugs for diseases. The present study clearly shows the medicinal uses of the plant, signifies the consumption of raw fruit for preventing diseases and will be helpful for pharmaceutical industries for the designing of new drugs for diseases. The work also emphasises the need for conservation of the species. © 2016, Global Research Online. All rights reserved.

There is a growing interest in developing and commercializing viscoelastic polyurethane foam suitable for pillow and mattress applications. In the present investigation, a novel combination of polyols with different molecular weights and hydroxyl values along with other ingredients were used for the preparation of viscoelastic polyurethane foam. The optimum polyol:isocyanate ratio was found to be 100:45 to yield a good quality foam. The physico-mechanical properties of the foam were measured as per standard procedures and compared with those of a commercially available viscoelastic foam sample. It was observed that the properties of the foam from this investigation were almost similar and in some aspects better than the properties of commercially available pillow foam. The foam can be further developed to make it suitable for hospital pillows and mattress applications. © Smithers Rapra Technology, 2011.

This investigation deals with the detailed procedure for the extraction of microfibrils from raw bamboo. The microfibrils obtained from raw bamboo were characterized using scanning electron microscope and the average diameter of the fibrils was found to be 10 μm. These microfibrils were then incorporated into polyhydroxybutyrate (PHB) matrix using conventional plastic processing equipments. The impact strength values of the resulting composites indicate that there is an optimum loading of microfibrils in the PHB matrix, beyond which the effect of fibril loading is not significant. © The Author(s) 2010.
