Hibiscus rosasinensis is member of the family Malvaceae, grow as green herbaceous plant in tropical regions. It is a tropical shrub, with large, glossy green leaves and spectacular trumpet shaped flowers. Its medicinal values have been mentioned in traditional folk medicines for variety of diseases. The objective of this study is to determine the phytochemical constituent using different solvent and to study the antibacterial effect of methanol extract at different concentration against three bacteria. Phytochemical screening of H. rosasinensis flower by four extraction solvents are carried out and antibacterial activity of three concentration of methanol extracts were screened against some bacteria such as Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. Methanol extract of hibiscus exhibits highest extraction yield value, followed by Ethanol, water and Ethyl acetate respectively. The phytochemical screening exhibited the presence of different component like Alkaloids, Glycosides, Carbohydrates, Phytosterols, Phenolic compound, Tannins, Saponins, Flavonoids, Proteins and Aminoacids. Methanol extracts at high concentration were exhibited maximum antibacterial potentiality of H. rosasinensis flower against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus respectively. The phytochemical analysis of Hibiscus rosasinensis flower extracts reported the present of different medicinal valuable constituents includes Alkaloids, Glycosides, Carbohydrates, Phytosterols, Phenolic compound, Tannins, Saponins, Flavonoids, and Proteins and Aminoacids. Our findings prove that, the flower of H. rosa-sinensis plants have medicinal antibacterial activities and can use against bacteria under study. Methanol extract obtained highest yield and antibacterial activity at high concentration, so it could be subjected to isolate different active medicinal valuable compound of H. rosasinensis L. The present findings suggest that methanol is a good solvent for extracting antibacterial agents. Further studies are needed to investigate individual phytochemical compound of the flower of Hibiscus rosasinensis. The flower extract of H. rosasinensis L. can be considered to be as equally potent as the most of effective artificial antibiotics.
