Biopotential activity of a rare medicinal plant - Wattakaka volubilis leaf

The use of medicinal plants for the treatment of various diseases is an old practice in most countries and it still offers an enormous potential source of new anti-infective agents. The present study was conducted to evaluate the antimicrobial activity of Wattakaka volubilis leaf extract. Antimicrobial activity of Wattakaka volubilis methanol extract is determined by disc diffusion method . The zone of inhibition of Wattakaka volubilis leaf extract against bacteria was maximum against Escherichia coli followed by Staphylococcus aureus, Proteus vulgaris. The least zone of inhibition was recorded against Pseudomonas aeruginosa . The Minimum inhibitory Concentration (MIC) ranged from 2 mg/ml to 4 mg/ml. For fungai , the zone of inhibition was maximum against Aspergillus Niger, Aspergillus flavus and Rhyzobium . The least zone of inhibition was recorded against tricoderma . The MIC was 0.5mg/ml.
