Comparative Antioxidant Activity of Twenty Traditional Indian Medicinal Plants and Its Correlation with Total Flavonoid and Phenolic Contentby

摘要

An endophytic fungus Acremonium sclerotigenum was isolated from the leaves of Terminalia bellerica and screened for siderophore production and antimicrobial (antibacterial, antifungal) activity. The endophyte was identified as Acremonium sclerotigenum based on 18S rDNA sequence analysis. The crude ethyl acetate extract showed potent antimicrobial activity against all test pathogens including gram positive (Bacillus cereus, Bacillus subtilis, Staphylococcus aureus) and gram negative (Escherichia coli, Pseudomonas aeruginosa) bacteria. Inhibition zones were more than 10 mm against E. coli, B. subtilis and B. cereus. The crude compound also showed siderophore activity.
