Antimicrobial activity of extracts from Pinus massoniana needles

Abstract: The antimicrobial activity of ethanol, acetone, and aqueous extracts from Pinus massoniana needles on four bacteria(Staphylococcus aureus, Escherichia coli, Bacillus subtilis, and Sarcina ventriculi) and three mold fungi(Trichoderma viride, Penicillium chrysogenum, and Aspergillus niger) was evaluated by agar-diffusion bioassasy. Filter paper discs impregnated with extracts at concentrations of 100.0, 50.0, 25.0, 12.5, 6.3, 3.1, 1.6 g·L-1 were placed on the agar surface. Reversal of the antiviral activity of mycophenolic acid was indicated by virus breakthrough in those cells in close proximity to the filter paper disc. All extracts, depending on their concentrations, showed different resistances to bacteria; however, their resistance to fungi differed. The assay showed that a 100.0 g·L-1 ethanol extract concentration of P. massoniana needles had a 25.6 mm diameter zone of inhibition against E. coli. For the three kinds of extracts, ethanol had the highest resistance and aqueous the lowest.The results shows that the extracts of P. massoniana needles have antimicrobial activity.
