The study was carried out on Launaea taraxacifolia leaves ethanolic extract for its antibacterial activity and phytochemical constituents. The leave extract was tested on five bacterial species such as Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniea, Candida albicans, Proteus spp., Bacillus subtilis and Streptococcus mutans. The ethanolic leave extract of Launaea taraxacifolia showed inhibitory effect on only 5 bacterial species which include Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniea, Candida albicans and Proteus spp. The ethanolic leave extract showed no effect on Bacillussubtilis but inhibited Streptococcus mutans at concentration of 25 μl. The inhibition zones for S. aureuswere 8 mm, 9 mm and 10 mm at concentrations of 15 μl, 20 μl and 25 μl respectively. The ethanolic extract displayed 6 mm, 8 mm and 9 mm against Proteus spp. At 25 μl concentration of extract the inhibition zone 13 mm was observed for Escherichia coli and Candida albicans. The phytochemical analysis showed the presence of Carbohydrates, Phenols, Tannins, Steriods, Cardiac glycosides, Flavanoids, Alkaloids, Terpenes, Proteins and Saponins.
