Abstract
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 activity under all the extraction solvents. 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.

Analysis of phenolic compounds in beetroot samples was carried out using High Performance Liquid Chromatography (HPLC) analysis, as described earlier with some modification [32]
0.8pulp (69.84 mg/100 g), whereas, among all, the methanolic extract of the beetroot pulp showed the lowest content of total phenolic compounds (18.5 mg/100Pulp g)
Summary
Beetroot (Beta vulgaris var. rubra L.; BVr) is a member of the Chenopodiaceae family, and it grows in temperate regions. Rubra L.; BVr) is a member of the Chenopodiaceae family, and it grows in temperate regions It is responsible for 20% of the world’s sugar production [1] and is usually consumed in powdered form, supplemental juice, bread, pickle, as well as pureed, boiled, and even processed as jam [2]. The nutritional composition of beetroot and its role in health and diseases has been presented in Tables 1 and 2 [7,8,9,10,11,12,13,14,15] These compounds possess many desirable properties such as antioxidant and antimicrobial activity, as well as anti-inflammatory, hypoglycemic, hepatoprotective, hypolipidemic, and antitumor properties [16,17,18,19,20].
