Fruit Anthocyanin Pigments of Red Raspberry Cultivars 1

Abstract

Abstract The distribution of cyanidin and pelargonidin fruit anthocyanins is presented for 37 red raspberry (Rubus idaeus L.) cultivars and selections. Nine cultivars contained 2 major fruit pigments, cyanidin 3-glucoside (Cy 3-G1) and cyanidin 3-sophoroside (Cy 3-Sop); 27 cultivars contained in addition 2 other major pigments, cyanidin 3-rutinoside (Cy 3-Ru) and cyanidin 3-glucosylrutinoside (Cy 3-G1Ru); and 1 selection ‘SHRI 6626/41’ contained in addition to the 4 pigments, cyanidin 3-sambubioside (Cy 3-Sam) and cyanidin 3-xylosylrutinoside (Cy 3-XylRu). Related pelargonidin glycosides were detected most cultivars and cyanidin 3, 5-diglucoside (Cy 3, 5-diG1) was detected in 13 cultivars.
