The present study is carried out to assess the quality of five plants, Coriandrum sativum, Mentha piperita, Tridax procumbens, Ocimum tenuiflorum and Catheranthus roseus for their phytochemical composition as medicine & their anti-bacterial effects. Phytochemicals of plants were obtained in aqueous & ethanolic extracts. These extracts are screened for the detection of secondary metabolites. Among five selected plants, aqueous and ethanolic extracts of leaf & stem have shown the presence of carbohydrates, alkaloids, steroids, glycosides, flavonoids, terpenoids and also oils & fats. But carbohydrates in leaves of Mentha & glycosides in leaves of Tridax of ethanolic extracts were found absent. Quinones were absent in both aqueous & ethanolic extracts except in the aqueous extract of stem of Ocimum. Tannins were found in both the extracts, but showed negative result in ethanolic extract of leaf of Ocimum. Quinones were absent in ethanolic extraction leaf & stems of all plants, but present only in the aqueous extract of stem of Ocimum. Tannins found in both aqueous & ehanolic extractions of stem & leaves of all plants except in the ethanolic leaf extract of Ocimum. Saponins found present in all but absent only in the ethanolic extract of stem of Tridax. Phenols found absent in aqueous extract of stems & ethanolic extraction of leaves of all plant, whereas they are found in aqueous extraction of all leaves except Tridax. Antimicrobial activity has shown the highest zone of inhibition by leaf extract of Vinca roseus (1.0 cm) on E.coli bacteria.
