Objective: To evaluate the anti-microbial activity of ethanolic extract of fruits of Annona reticulata (family-Annonaceae) in conjugation with phytochemical analysis.Methods: The ethanolic extract of fruits of Annona reticulata (family-Annonaceae) was prepared by Soxhlet extraction and analysed for phytochemical constituents using standard methods. The anti-microbial activity of the plant extract was examined against bacterial strains and fungal strains using disc diffusion method.Results: The present investigation shows the phytochemical analysis, anti-microbial activity of the ethanolic extract of the plant Annona reticulata. Various phytochemical analyses revealed the presence of alkaloids, saponin, flavonoids, carbohydrates, glycosides, steroids, proteins and amino acids and tannins. The anti-microbial activity of the ethanolic extract of the plant showed significant result against all the of the test organisms.Conclusion: The present study concluded that ethanolic extract of fruits of the Annona reticulata contain high presence of phytochemicals. The ethanolic extract of the plant was found to possess promising anti-microbial activity when compared with the standards.

Objective: To estimate the anti-microbial activity of ethanolic extract of Delonix regia (Hook.) Raf (family-Leguminosae) in association with phytochemical analysis.Methods: The ethanolic extract of the bark of Delonix regia (Hook.) Raf was prepared and investigate for phytochemical constituents using standard methods. Antimicrobial activity of ethanolic extract of were carried out against one Gram positive bacteria= Staphylococcus aureus and one Gram negative bacteria= Escherichia coli. The anti-fungal activity of the plant extract was evaluated on Candida albicans. The testing was done by the disc diffusion method. A zone of inhibition of ethanolic extract was compared with that of standard Amikacin for anti-bacterial activities and Fluconazole for anti-fungal activity.Results: The present investigation shows the phytochemical analysis, antimicrobial activity of the ethanolic extract of the bark of Delonix regia (Hook.) Raf. Various phytochemical analyses revealed the presence of alkaloids, anthraquinone, phenol, terpenes, cardenolides, phlobatannins, tannin, chalcones, steroids. The anti-microbial activity of the ethanolic extract of the plant showed significant results against all three of the test organisms.Conclusion: The present study concluded that ethanolic extract of the bark of Delonix regia (Hook.) Raf contains the high existence of phytochemicals. The ethanolic extract of the plant was found to possess promising antimicrobial activity when compared with the standards.

Objective: To estimate the anti-microbial activity of ethanolic extract of Punica granatum seeds (family-Punicaceae) in association with phytochemical analysis.Methods: The ethanolic extract of the seeds of Punica granatum was prepared and investigate for phytochemical constituents using standard methods. Antimicrobial activities of ethanolic extract were carried out against one Gram positive bacteria (Staphylococcus aureus) and one Gram negative bacteria (Escherichia coli). The anti-fungal activity of the plant extract was evaluated on Candida albicans. The testing was done by the disc diffusion method. A zone of inhibition of ethanolic extract was compared with that of standard Tetracycline for anti-bacterial activities and Fluconazole for anti-fungal activity.Results: The result of this study showed a good antibacterial effect of pomegranate juice against both Gram negative and Gram positive bacteria. The antimicrobial activity of the fruit may be due to its high content of polyphenols which causes phenolic toxicity by interfering with the sulfhydryl group of the bacterial proteins and high content of tannins which interferes with bacterial membrane stability.Conclusion: The present study concluded that ethanolic extract of the seeds of Punica granatum contains the high existence of phytochemicals. The ethanolic extract of the plant was found to possess promising antimicrobial activity when compared with the standards.
