Preliminary Phytochemical screening and in vitro antimicrobial activity of Aqueous, Ethanol, Methanol and Chloroform leaf extracts of Hiptage benghalensis collected from different altitudes of Tiruchirappalli districts namely Srirangam Brindhavanam and Pacchai malai were evaluated for their phytochemical constituents and antimicrobial potency against selected pathogens such as Enterobacter aerogenes, Escherichia coli, Streptococcus aureus, Proteus vulgaris, Helicobacter pylori, Candida albicans, Aspergillus flavus, Pseudomonas aeruginosa and Trichosporan asahi, at different concentrations of 25 µg, 50 µg, 75 µg and 100 µg respectively. Streptomycin and Ketoconazole were used as positive control, while, the respective solvents served as the negative control. The results obtained showed that there were minor variations in the phytochemical constituents among the leaf extracts collected from the plains of Srirangam and the hill top of Pacchai malai. Antimicrobial investigation of all the leaf extracts exhibited significant antimicrobial activity with ethanol extracts of the leaf showing highest potency. However, notable potency was observed with the leaf extracts obtained from higher altitude.
