ANTIBACTERIAL AND PHYTOCHEMICAL STUDIES ON THE LEAVES OF ADENOCALYMMA ALLIACEUM MIERS.Abstract
Adenocalymma alliaceum is an important medicinal plant belongs to the family Bignoniaceae. The antibacterial and phytochemical studies on the leaves of this plant were carried out by using the disc diffusion method and Thin Layer Chromatography. The methanolic leaf extract showed a brown colored band on TLC plate with an Rf value 0.25 represents the presence of sulfide compound. The extract was tested against four bacterial strains, namely Enterobacter aerogenes, Salmonella enterica, Vibrio cholerae (gram positive) and Streptococcus haemolyticus (gram negative). The activity was determined by measuring the diameter of zone of inhibition in mm. The result obtained from the present study indicates that the methanolic leaf extract was active only against gram-positive bacteria. The maximum zone of inhibition was recorded in Salmonella enterica (12 mm).
