RSL plant material for varieties NFR-S-4 and NBR-S-16. Compounds were quantified by HPLC using UV peak areas of compound standards. Cyanidin malonyl-glucoside content was quantified as cyanidin 3-glucoside equivalents (C3G eq.). Quercetin malonyl-glucoside content was quantified quercetin 3-glucoside equivalents (Q3G eq.). Results are presented as the means ± SE.
