Description of the Guelder Rose Fruit in Terms of Chemical Composition, Antioxidant Capacity and Phenolic Compounds

The Viburnum opulus (guelder rose) fruit is a Polish native fruit that grows across almost the entire territory of the country, except for the Tatra Mountains. The fruits are rich in nutrients and biologically active compounds, however, they are rarely used for food production or as a dietary ingredient. This study assessed this fruit for dry matter (17.3% +/- 0.7), extract (13% +/- 0.53), titratable acidity (1.78 g/100 g +/- 0.48), pectin (1.10% +/- 0.97), vitamin C (47.79 mg/100 g +/- 1.02), the amount of sugar identified as fructose (6.85 g/100 g +/- 0.67), antioxidant activity, ABTS (14.64 +/- 0.61 mu M Trolox/100 g), FRAP (211.14 +/- 1.04 mu M Trolox/100 g) and total polyphenolic content TPC (1695.88 +/- 0.86 mg GAE/100 g). The analysis of phenolic identification was performed using the ACQUITY Ultra Performance LC (UPLC) system with the binary solvent manager and PDA detector.
