Abstract

 

Characterization of preliminary phytochemical components of Aframomum danielli seeds was determined. Fractions of the seeds obtained by vacuum liquid chromatographic process were tested for antimicrobial activities. Phytochemical screening revealed the presence of alkaloids, cardenolides, carotenoids and polyphenols. All fractions obtained from the petroleum ether extract exhibited antimicrobial activity on food-borne pathogens with minimum inhibitory concentrations in the range of 100 – 800 microgram per millilitres.

 

Key words: Phytochemicals, A. danielli fractions, antimicrobial properties.
