Abstract
The present paper deals the antioxidant activity of alcoholic extract of leaves of Mucuna pruriens (MP) of family Fabaceae. The concentration of alcoholic extract were (3-800 ug/ml). The MP showed maximum scavenging activity at concentration of 800 μg/ml. The antibacterial activity of the alcoholic extract of Mucuna pruriens leave was carried out and it was determined by the cup plate and disc plate methods against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis. Streptomycin was used as a positive control. The zone of inhibition of alcoholic extract of MP against various microorganisms was measured and compared with standard control, MP showed maximum activity at the concentration of 200 mg/kg against all the bacterial strains, Maximum antibacterial activity against Bacillus subtilis and Pseudomonas aeruginosa and exhibited moderate antibacterial activity against Staphylococcus aureus and Escherichia coli. The antioxidant activity of MP and antimicrobial activity may be due to presence of the active principle present in MP leaves. The presence of flavonoids, alkaloids, tannins, amino acids, proteins, glycosides, carbohydrates etc. Phytochemical analysis intended to serve as a major resource for information on analytical and instrumental methodology in the plant sciences.
