Abstract

An in vitro antimicrobial activity and phytochemical analysis of various extracts of Indigofera trita check for this species in other resources L. viz. petroleum ether, chloroform, acetone, ethanol and aqueous extracts were carried out. A total of 21 microorganisms (19 bacteria and 2 fungal strains) were used for antimicrobial activity by disc diffusion method and a standard procedure was used to identify the phytochemical constituents. Petroleum ether extract showed moderate inhibitory activity against Staphylococcus aureus check for this species in other resources (14.40 mm), S. epidermidis check for this species in other resources (14.20 mm), Salmonella paratyphi check for this species in other resources A (12.80 mm), Streptococcus mutans check for this species in other resources (12.20 mm), Escherichia coli check for this species in other resources , Proteus vulgaris check for this species in other resources , S. typhi check for this species in other resources and Burkholderia cepacia check for this species in other resources (12.00 mm). The chloroform extract also showed antimicrobial activity against S. epidermidis (14.20 mm), S. typhimurium check for this species in other resources (12.60 mm), S. paratyphi A, S. brunei and Yersinia enterocolitica check for this species in other resources (12.00 mm). The acetone extract of I. trita showed considerable inhibitory activity against S. epidermidis (18.20 mm), S. typhimurium (14.60 mm), S. infantis check for this species in other resources (13.80 mm), S. aureus (13.40 mm), Y. enterocolitica (13.00 mm) and Enterobacter aerogenes check for this species in other resources (12.00 mm) were documented. Ethanol extract showed significant antimicrobial activity against S. epidermidis (18.60 mm), S. paratyphi A (14.60 mm), Y. enterocolitica (13.40 mm), S. typhi (12.40 mm), S. aureus, E. aerogenes, S. typhimurium and S. infantis (12.00 mm). Aqueous extract of I. trita considerably inhibited S. epidermidis (13.80 mm), S. paratyphi A and Y. enterocolitica (12.20 mm), E. aerogenes and Haemophilus parahaemolyticus check for this species in other resources (12.00 mm). All the five extracts showed a minimal antifungal activity when compared to antibacterial activity. The result revealed that the antimicrobial properties of I. trita might be associated with the presence of phenolic compounds, flavonoids, tannins, glycosides, saponins, phytosterols and alkaloids.
