Abstract

Seabuckthorn (Hippophae rhamnoides) seeds aqueous extract was screened for antioxidant and antibacterial activities. The antioxidant activities (reducing power, DPPH and liposome model system) showed a good antioxidant activity. The extract was also found to possess antibacterial activity with a MIC values with respect to Listeria monocytogenes and Yersinia enterocolitica found to be 750 and 1000 ppm, respectively. The antioxidant and antimicrobial effects of the extract implicate its potential for natural preservation.
