In vitro antibacterial activity of some medicinal plants of Garhwal

Ethanol, methanol and acetone extracts of leaves of Prunus cerasoids, Myrica esulenta, Artemisia capillaries and Rhus parviflora and stem barks of R cerasoides, Pyrus pashia. Premna Barbata and R. parviflora were assayed for antibacterial activity against Staphylococcus aureus, E. coli, Streplococcus mutans, Staphylococcus epidermidis, Klebsiella pneumoniae, Bacillus subtilis and different hospital strains employing Agar well and disc diffusion methods. MIC and MBC value of effective extracts against test organisms were observed. Ethanol extracts gave best results followed by acetone and methanol extracts. Variations in response of test organisms are reported and discussed herein.
