Physicochemical characteristic and comparative in-vitro anti-microbial activity of leaves, stem, berries of laurus nobilis.l and anti oxidant activity of leaves of laurus nobilis.l of a malaysian species

Plants are natural sources consists of many natural derived products. In ancient times the herbals are taken in raw to cure much disease, the development of science and technology investigates that there are some active compounds which plays the major role in curing the disease. Various plant and its parts such as leaf, stem, fruit and roots contains the different types of active substances against the inhibition dreadful diseases. In this current study Laurus nobilis.L parts were extracted using the suitable solvent and studied for the various types of microbial assay and anti oxidant activity. The stem and fruit extracts shows no inhibition activity where as the leaf extract shows the bioactivity against the Pseudomonas sp, Escherichia coli and no effect on Vibrio cholera and fungi. The bay leaf extract shows 60.57% activity in xanthine oxidase assay,for DDPH assay 5 mg/ ml s 77.59% activity, cupric shows the 60.83% activity in 5 mg/ ml and Beta Carotene Assay as 69.25% respectively.
