Evaluation of Phytochemical and Antibacterial Potential of Helicteres Isora L. Fruits Against Enteric Bacterial Pathogens
Antibacterial activities of aqueous, acetone, ethanol and methanol extracts of fruits of Helicteres isora (Mororphali) were studied. The fruit aqueous extracts of H. isora showed prominent antibacterial activities against E.coli, Staphylococcus epidermidis, Salmonella typhimurium and Proteus vulgaris; moderate activity against Enterobacter aerogenes, Staphylococcus aureus, Salmonella typhi and least activity against Pseudomonas aeruginosa. The aqueous extract showed maximal, the ethanol and methanol extract moderate and acetone extracts least antibacterial activities. Phytochemical screening revealed the presence of carbohydrates, anthraquinon glycosides, proteins, tannin and phenolic compounds and steroids These antibacterial properties supports its traditional use of fruits of H. isora in the treatment of enteric or diarrhoeal infections
Screening of Antibacterial Potentials of Some Medicinal Plants from Melghat Forest in India
Cyperus rotundus, Caesalpinia bonducella, Tinospora cordifolia, Gardenia gummifera, Ailanthus excelsa, Acacia arabica, Embelia ribes and Ventilago maderspatana from Melghat forest were screened for their antibacterial potential against Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Proteus vulgaris, Salmonella typhi, Shigella flexneri, Salmonella paratyphi, Salmonella typhimurium, Pseudomonas aeruginosa, Enterobacter aerogenes by disc diffusion method. Out of these medicinal plants Caesalpinia bonducella, Gardenia gummifera and Acacia arabica showed remarkable antibacterial potential. The phytochemical analysis had showed the presence of Cardiac glycosides in all extracts (aqueous, acetone, ethanol and methanol) of Acacia arabica, Gardenia gummifera and ethanol, methanol extracts of Caesalpinia bonducella. Flavonoids were present in Gardenia gummifera, Ailanthus excelsa and acetone, methanol extracts of Acacia Arabica. Tannins and phenolic were present in Cyperus rotundus, Embelia ribes, and organic extracts of Ventilago maderspatana
