Germ-inhibiting inspection of gradient extracts of Marsilea minuta L.

Marsilea minuta L. commonly known as “Choupatti”, is a healing pteridophyte. The plant acts against inflammation. In the current study, whole plant of Marsilea minuta L. was analyzed for its antibacterial nature and phytochemical components in different solvents extracts of accelerating polarity towards different disease causing bacteria. Disc diffusion method was used to analyse antibacterial activity. The plant primarily exhibited antibacterial activity in ethanol extract. Maximum intensity of activity was noticed towards Pseodomonas aeruginosa, a resistant strain towards amoxicillin and chloramphenicol. Petroleum ether and water extracts could not show any antibacterial activity towards the tested organisms. Occurrence of flavonoid and phenol in ethanol extract of the plant may be responseible for antibacterial activity. Ethanol extract of the plant showed minimum inhibitory concentration as 18.75 mg/ml and minimum bactericidal concentration as 37.5 mg/ml towards Pseudomonas aeruginosa.
