Evaluation of some chemical constituents, antioxidant, antibacterial and anticancer activities of beta Vulgaris L. Root

Abstract

Beta vulgaris is belonging to the family Chenopodiaceae and has several varieties with bulb colors ranging from yellow to red. Deep redcolored beet roots are the most popular for human consumption, both cooked and raw as salad or juice. The ethanolic extract of beetroots contains valuable and active compounds such as carotenoids, phenols, flavonoids, tannin, alkaloids, vitamins C, B3, B6 and B9. Therefore, beetroot extract has antioxidant and antimicrobial activity against gram positive and negative bacteria. Gram-positive bacteria Staphylococcus aureus and Bacillus cereus demonstrated higher susceptibility than Gramnegative Escherichia coli and Pseudomonas typhimureum. Beta vulgaris ethanolic extract exhibit significant anticancer activity against lung (A549) but slight effect against colorectal adenocarcinoma Caco-2 cell lines at the high concentrations of ethanolic extract (800 ?g/ml).
