Antimicrobial activities of Aerva javanica and Paeonia emodi plants

ABSTRACT

Aerva javanica and Paeonia emodi plants extracts were studied for antibacterial activity against Escherichia coli [NCTC 10418], Klebsiella pneumoniae [ATCC 700603], Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi, Staphylococcus epidermidis [NCTC 11047] and Methicillin Resistant Staphylococcus Aureus [MRSA] [NCTC 13143] and antifungal activity against Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger and Fusarium solani. Extracts were obtained by using methanol, n-hexane, chloroform, ethyl acetate and aqueous fraction. The extracts of Paeonia emodi and Aerva javanica showed significant antibacterial activity but only Salmonella typhi was resistant to Aerva javanica. Moreover, the antifungal activity of Aerva javanica was very poor but the fractions of Paeonia emodi showed sufficient inhibition against fungal strains
