Abstract
The total phenolic and flavonoid amounts of the parts of sugar beets were recorded to be between 10.04 (root-outer) and 353.17 mg GAE/100 g (leaf) to 41.19 (root-inner) and 800.71 mg/100 g (leaf), respectivley. Also, antioxidant capacity values of sugar beet parts were monitored to be between 2.05 (root-outer) and 6.99 mmol/kg (leaf). Gallic and 3,4-dihydroxybenzoic acid results of the parts of sugar beets were recorded to be between 10.56 (root-inner) and 18.24 (peel) to 1.46 (root-inner) and 31.48 mg/100 g (leaf), respectively. While gallic acid contents of the stem and underground parts of sugar beet increased compared to sugar beet leaves, the amounts of other phenolic components decreased significantly. The highest protein content was detected in beet leaves and stems, followed by root-inner, peel, crown + neck and tail in descending order. Dominant macro element contents of sugarbeet parts were P, K, Ca, Mg and S. Potassium quantities of sugar beet parts were reported to be between 4741.59 (root-outer) and 27,670.12 mg/kg (stem). The results obtained showed significant variations depending on the beet parts. In general, the macro and micro element amounts of the leaves and stems of the beets were higher than the underground parts of the beets.
