Composition of biologically active substances of Vaccinium berries growing in the northwestern region of Russia

Abstract

Using gas chromatography with preliminary derivatization of samples, the composition of the biologically active substances of wild-growing cranberries (Vaccinium oxycoccos L.) and lingonberries (Vaccinium vitis idaea L.) was studied. Biologically active substances contain phenolic compounds, tocopherols and phytosterols. Flavonoids prevail in the composition of phenolic compounds, the amount of which increases in berry press residues. Cranberries and lingonberries differ in the quantitative and qualitative composition of flavonoids and phenolic acids. In fresh cranberry berries, taxifolin and morin predominate among flavonoids; catechin and taxifolin predominate in lingonberries. In berry press residues, the number of flavonoids increases due to taxifolin and qercetin B, and in lingonberries, additionally due to catechin. Chlorogenic acid predominates in the composition of phenolic acids of fresh cranberries; 4-Oxybenzoic acid predominates in fresh lingonberries. Tocopherols quantitatively prevail in whole lingonberries, and phytosterols predominate in cranberries. In the berry press residues, their number increases.

Development and Validation of the UPLC-DAD Methodology for the Detection of Triterpenoids and Phytosterols in Fruit Samples of Vaccinium macrocarpon Aiton and Vaccinium oxycoccos L.

“…In a study by Klavins et al, the β-Sitosterol content of 3150 µg/g found in the extract of the waxy layer of large cranberry fruit was higher than the amount of β-Sitosterol found in our study [ 22 ]. Meanwhile, in a study by Nilova et al, the level of β-Sitosterol (4 µg/g) found in berry press residues of cranberries was significantly lower than that detected in our study [ 50 ].…”

Influence of Altitudes and Development Stages on the Chemical Composition, Antioxidant, and Antimicrobial Capacity of the Wild Andean Blueberry (Vaccinium floribundum Kunth)

“…The TFC concentration range of the fruits at different altitudes and ripeness stages ranged from 12.44 to 37.71 mg Cateq/g FW ( Table 4 ). Previous studies on V. floribundum Kunth [ 43 , 44 ], V. corymbosum L. [ 60 ], and Vaccinium vitis idaea L. [ 61 ] corroborate our results. According to the results obtained, TFC was also affected by the different altitudes of the production sites and the ripeness stage.…”
