Beetroot is a widely consumed crop all over the world and contains plenty of bioactive compounds. In this study, we analyzed the bioactive as well as the antimicrobial properties of the oven-dried beetroot (pulp and peel) using different solvents. The 50% methanolic extract yielded the highest content of total polyphenols and total flavonoids as well as the reducing power of the beetroot. The beetroot peel exhibited a higher content of total polyphenols, total flavonoids, and reducing power

Mixture of methanol and water (50% v/v) extracted the highest chlorogenic acid (78.24 mg/100 g) of the dried beetroot peel, while 1,2-dihydroxybenzene was the most noteworthy phenolic compound (42.52 mg/100 g) in beetroot peel methanolic extract. The 50% methanolic extract of both peel and pulp demonstrated the highest antibacterial and anticandidal potential. These results can be helpful for beetroot consumption.
