ABSTRACT

This study was carried out with an objective to investigate the antimicrobial activity of tubers of Arisaema leschenaultii. The aim of the study is to assess the antimicrobial activity and to determine the zone of inhibition of extracts on some bacterial and fungal strains. In the present study, the microbial activity of Ethanolic and Aqueous extract of Arisaema Leschenaultii was evaluated for potential antimicrobial activity against medically important bacterial and fungal strains. The antimicrobial activity was determined in the extracts using MIC and zone of inhibition method. The antibacterial and antifungal activities of ethanolic and aqueous extracts of Arisaema Leschenaultii were tested against Gram-positive, Gram-negative fungal strains—Aspergillus niger, Aspergillus flavus, Candida albicans. MIC and Zone of inhibition of extracts were compared with that of different standards like ciprofloxacin, for antibacterial activity and ketoconazole for antifungal activity. The results showed that the remarkable inhibition of the bacterial growth was shown against the tested organisms. The phytochemical analyses of the plants were carried out. The antimicrobial activity of the Cassia fistula was due to the presence of various secondary metabolites. Hence, these plants can be used to discover bioactive natural products that may serve as leads in the development of new pharmaceuticals research activities.

Keywords: Anti-microbial activity, Arisaema leschenaultia.
