IN VITRO ANTIBACTERIAL ACTIVITY OF ETHANOLIC EXTRACT OF VETIVERIA ZIZANIOIDES ROOT

摘要

Objective: To evaluate the antibacterial activity of ethanolic extract of roots of Vetiveria zizanioides. Method: Ethanolic extract of roots of Vetiveria Zizanioides was prepared. Standard cultures of Escherichia coli NCIM 2118; Bacillus subtilis NCIM 2063, P. aeurogenosa NCIM 2036 and Staphylococcus aureus NCIM 2079 were used for the study. The antibacterial tests used were the agar well plate method. Ciprofloxacin was used as the positive control. Results: EEVZ does not show any activity against B.subtilis. However, the activity was less than the standard Ciprofloxacin. The extract shows increasing inhibitory activity with increase in concentration (150-750μg). Conclusions: From our investigation, for screening ethanolic extract of Vetiveria zizanioides the results obtained confirmed therapeutic potency of some plants used in traditional medicine. The plants could be potential source of new antimicrobial agent.
