IN VITRO EVALUATION ANTIBACTERIAL POTENTIALITY OF AQUEOUS EXTRACT OF OPERCULINA TURPETHUM (L.) SILVA (ROOT) AGAINST IMPORTANT SPECIES OF BACTERIA
*Dr. Kiran B., Padmini N. and Dr. Jyothi Bala Chauhan
Aqueous extract of Operculina turpethum root was evaluated against six bacterial speies viz., Escherichia coli, Enterobacter aerogenes, Klebsiella oxytoca, Proteus vulgaris, Bacillus cereus and Staphylococcus aureus tested at 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100% concentration respectively. Maximum inhibition was observed in Staphylococcus aureus (37.0mm at 100% concentration) followed by Bacillus cereus, Proteus vulgaris and E.coli and recorded 34.0mm at 100% concentration. E.aerogenes and K.oxytoca recorded 33.0 mm at 100% concentration. Significant inhibition was also observed from 10 to 90% concentration against all the test bacterial species. Compared to standard antibiotic Gentamycin at 25mg concentration, Operculina turpethum showed significant activity.
Keywords: Operculina turpethum, Aqueous extract, Antibacterial activity, Gentamycin.
