Abstract
In ayurveda, herbal formulations have been used for its medicinal and therapeutic applications since ancient days. Plants are rich source of phytochemicals and have been explored for treatment of various diseases. In the present investigation, antimicrobial evaluation of a novel polyherbal formulation(PHF) containing of Trigonella foenum graecum, Cinnamomom verum, Aquilaria malaccensis, Azadirachta indica, Nigella sativa and Carthamus tinctorious was done. Phytochemical investigation revealed the presence of alkaloids, flavonoids, saponins, tannins, and glycosides. For antibacterial study, ofloxacin was used as standard drug; gram positive bateria- Bacillus subtilis, Shigella dysenteria and Staphyllococcus aureus and gram negative bacteria-Psuedomonas aeroginosa and Escherichia coli were used. For antifungal activity, ketoconazole was used as standard drug; Candida albicans and Aspergillus niger were used. The ethanolic extract of the PHF demonstrated better antimicrobial activity than the petroleum ether extract. The zone of inhibition was strong for 100µg/ml ethanolic extract against gram positive, gram negative and fungi strains. The PHEE3 showed significant activity of 21±0.421 to 26.83±0.404mm, then by PHEE3 ranging between 20.5±0.763 to 26.1±0.477 mm against all strains of microbes used suggesting synergistic action by the plants used. Presence of phytochemicals like tannins, flavonoids and other hydroxylated polyphenols, formed as secondary metabolites may be responsible for the antimicrobial activity of the PHF.
