Phenolic contents and antimicrobial activity of squirting cucumber (Ecballium elaterium) extracts against food-borne pathogens
Journal Title: Pakistan Journal of Pharmaceutical Sciences - Year 2014, Vol 27, Issue 3
Abstract
Squirting cucumber (Ecballium elaterium), is an indigenous species of the south of Europe and the Mediterranean basin, sometimes cultivated for its use as a medicinal plant. This study compared phenolic contents in Ecballium elaterium organs and their antimicrobial activities against some foodborne pathogens. Our results indicated that the plant organs had different total polyphenol contents (ranging from 6.744 to 46.848 mg GAE g-1 DW) the leaves and fruits contained about 6-fold higher phenol contents than the root. The same tendency was observed for flavonoid and tannin levels. An interesting antimicrobial activity was also observed against the food pathogens at concentrations ranging from 0.004 to 2.5 mg ml-1. Ecballium elaterium extracts might therefore be a potential source of preservative candidates for use in food or pharmaceutical industries.
