The present study is used to investigate the presence of Phytoconstituents, nutrients and antibacterial activity of Cardiospermum halicacabum Linn. Phytochemical analysis of leaf material revealed that antibacterial activity of plant material is because of the presence of phenolic compounds. Macroelement calcium and microelements iron were observed in high amount through Flame Emission Spectroscopy and Atomic absorption Spectroscopy respectively. Ethanol and hexane extracts from Cardiospermum halicacabum were investigated for their invitro antibacterial properties against 4 bacterial pathogens like Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, and Klebsiella pneumoniae. The results obtained in the present study suggested that Cardiospermum halicacabum were more active against gram-negative bacteria. https://www.biotech-asia.org/vol5no2/assessment-of-phytoconstituents-nutrients-and-antibacterial-activity-of-cardiospermum-halicacabum-linn/ Medicinal plant; Cardiospermum halicacabum; phytochemical; nutritive value
