Preliminary phytochemical content and antibacterial activity of Ukshi (Calycopteris floribunda Lam.) leaves

Abstract

Calycopteris floribunda Lam. is a large diffuse or scandent, climbing shrub belongs to the family Combretaceae. In this study, various solvent extracts (petroleum ether, chloroform, ethyl acetate, methanol and aqueous) of Calycopteris floribunda leaves were investigated for phytochemical and antibacterial activities. Among the other solvent extracts, ethyl acetate extract of leaves was showed the effective results for alkaloids, tannins, flavanoids, resins, cardiac glycosides, phenols, terpinoids, sterols and saponins. The leaves of Calycopteris floribunda showed the presence of terpinoids, sterols, alkaloids and flavanoids. The methanolic leaf extract was showed the better antibacterial activity against the four pathogenic bacteria strains such as Bacillus subtilus, Pseudomonas arginoses, Actinomycetes sp. and Seratia sp. than the other solvent extracts. Among the other bacteria, Bacillus strain was highly affected by the leaf extract.
