Comprehensive Spectroscopic Analysis of Phenolic Compounds of Cloudberry Populations in Belarus.

Research on the composition of phenolic compounds in extracts of leaf blades of cloudberry (Rubus chamaemorus L.) populations from Lonno, Yelnya, Boloto Mokh, and Zhada reserves was conducted. The highest content of phenolic compounds was observed in the female clone of the Lonno population and amounted to 651.54 ± 21.64 mg-equiv of gallic acid per g of extract, of which 53.5 ± 5.01 mg-equiv of rutin per g of flavonoid extract. The following phenolic compounds were identified in the extracts using chromatography–mass-spectrometry: quercetin-3-O-xyloside, ellagic acid, quercetin-3-O-glucoside, quercetin-3-O-glucuronide, kaempferol-3-β-D-glucopyranoside, chlorogenic acid, and rutin. The contents of kaempferol-3-β-D-glucopyranoside, quercetin-3-O-glucoside, ellagic acid, and rutin were determined. [ABSTRACT FROM AUTHOR]
