"Evaluation of nutritional, phytochemical, antioxidant and antibacterial activity of dried plum (Prunus domestica)"

Abstract

The nutritional, phytochemical, antioxidant and antibacterial activity of dried plum (Prunus domestica) were studied to understand its health benefits. The nutritional composition proved its potential as an energy source with low fat content. Protein and dietary fiber content obtained were 3.80% and 2.79% respectively. It was found to be a moderate source of minerals like magnesium, calcium, iron as well as other nutrients. The phytochemical analysis of the dried fruit revealed it to be a good source of total phenolic and flavonoids. The extract has a moderate antioxidant potential, thus confirming it as a potent electron and hydrogen donor. The GC/MS screening exhibited the presence of vitamin E, furfural, phytosterol, fatty acids, eugenol and maltol which have different therapeutic uses. In preliminary study, the extract was screened against four bacterial strains. It showed a highest zone of inhibition against Staphylococcus epidermidis followed by Staphylococcus aureus and Proteus mirabilis.
