Morinda tinctoria

There is an increasing commercial demand for nanoparticles due to their wide applicability in various areas such as electronics; catalysis, chemistry, energy, and medicine Nanoparticles are prepared by a variety of chemical methods which are not environmentally friendly. We report a rapid and convenient method to reductively prepare silver nanoparticles using silver nitrate In this report we use aqueous extracts from plants namely Morinda tinctoria, Michelia champaca. The extracts template the reductive preparation of silver nano particles which are found to be < 100 nm in size. The synthesized compounds are characterized by FT-IR, UV_VIS and XRD data.  Green synthesized silver nanoparticles showed antibacterial activity against two Gram-positive bacteria Staphylococcus aureus, Bacillus subtilis and two Gram-negative bacteria Pseudomonas aeruginosa, Escherichia coli and antifungal activity against Candida albicans, Aspergillus niger and Cryptococcus neoformans.  The synthesized nano particles were found to be highly toxic against different multi drug resistant human pathogens

The present study was designed to investigate te antioxidant activity oof methanolic extract of Morinda Tinctoria Roxb against (MEMT) fruits in the cerebral ischemia induced animal model system.  Global cerebral ischemia was induced by temporary bilateral common carotid  artery occlusion for 15 min followed by reperfusion in Sprague Dawley Rats  and the animals were pre-treated with MEMT (200 and 400 mg kg-1) for 1 week before induction. After induction of ischemia by BCCAO animals were again treated with MEMT for 1 week and the animals were sacrificed. Homogenized content of brain were estimated in control, sham and treatment groups. The MEMT showed the significance of p
