Abstract:
Medicinal plants are considered rich source of ingredients, known to be a potential source of therapeutics or curative aids. The plant product or natural products have an important role in disease prevention and treatment through the enhancement of antioxidant activity and inhibition of bacterial growth. Medicinal plants have good cultural acceptability, closeness and adaptability with human body. Phytochemical constituents such as flavonoids and tannins are present in medicinal plants which depicts their activities in development of medicines. For better health conditions and to maintain human wellbeing, a lot of undeveloped and developed countries use plants in medical sense. These medicinal plants have therapeutics implication in treatment and formulation based on the fact that these contain various active compounds which is worthiest in usage and are also used to treat various diseases. The current study is aimed to investigate the antimicrobial activity of selected medicinal plant extracts (Azadirachta indica & Allium cepa) against selected bacterial strains, named as Bacillus cereus, Bacillus subtilis, Escherichia coli & Staphylococcus aureus. Both neem and onion extract were applied on bacterial strain from 150mg/ml concentration to 250mg/ml. Extracts showed effective results against all test strains. The MIC of ethanolic extract of neem was proved most effective against the Escherichia coli & Staphylococcus aureus at 220mg/ml. While onion inhibitory effect was maximum for Bacillus subtilis at concentration of 200mg. Effect of both extracts was tested by heating extract solution at diverse temperature and at different pH. Zone of inhibition was measured. The means of all zones of inhibition was compared by using one - way ANOVA.
