MIC VALUES OF INFLORESCENCE AND LEAVES EXTRACTS OF ACHYRANTHES ASPERA AGAINST USUAL PATHOGENIC BACTERIAL STRAINS

Achyranthes aspera is an important medicinal herb that possesses many therapeutic properties. Present study was carried out to evaluate minimum inhibitory concentration values of inflorescence and leaves extracts of A. aspera against various pathogenic strains of bacteria i.e. Escherichia coli, Bacillus cereus, Staphylococcus epidermis, Shigella flexineri and Pseudomonas aeruginosa. Increasing the dilution from the stock solution i.e. 100 µg/ml, in order to 2 times i.e. 50 µg/ml, 4 times i.e. 25 µg/ml and 8 times i.e. 12.5 µg/ml, the concentration of active antimicrobial compound was found to be decreased. Decreased absorbance with varying concentrations of plant extracts indicated that minimum concentration of various plant extract is enough to inhibit the growth of bacteria. For both plant parts, all the extracts have MIC values ranges from 12.5-100 µg/ml for various pathogenic strains.
