Characterization Of Nutritional Supplement With Content Of Vaccinium Macrocarpon Based On Comparison Of Chosen Flavonol Glycosides By Htgc-Ms 126

High temperature gas chromatography with mass detector was used for separation and determination of high molecular weight compounds: glycosidized flavonols. This method was used for determination of glycoside derivates of quercetin in the form of quercetin 3-O-beta-D-galactoside, quercetin 3-O-beta-D-glucoside, and quercetin 3-O-alpha-D-arabinoside. After two-step derivatisation process, selected flavonol glycosides derivates were identified in four samples of a nutritional supplement containing cranberry extract, cranberry jam and three samples of the dried berries. The determined values of the total content of the investigated substances in the samples were significantly differentandare in range of 5-16400 mg kg(-1).
