The qualitative and relative quantitative anthocyanin content of 19 species belonging to the genera Sambucus, Lonicera and Viburnum in the family Caprifoliaceae has been determined. Altogether 12 anthocyanins were identified; the 3-O-glucoside (2), 3-O-galactoside (5), 3-O-(6-O-arabinosylglucoside) (7), 3-O-(6-O-rhamnosylglucoside) (9), 3-O-(2-O-xylosyl-6-O-rhamnosylglucoside) (10), 3-O-(2-O-xylosylgalactoside) (11), 3-O-(2-O-xylosylglucoside) (12), 3-O-(2-O-xylosylglucoside)-5-O-glucoside (14), 3-O-(2-O-xylosyl-6-O-Z-p-coumaroylglucoside)-5-O-glucoside (15) and 3-O-(2-O-xylosyl-6-O-E-p-coumaroylglucoside)-5-O-glucoside (16) of cyanidin, in addition to the 3-O-glucosides of pelargonidin and delphinidin (1 and 3). Pigment 7 is the first complete identification of the disaccharide vicianose, 6-O-alpha-arabinopyranosyl-beta-glucopyranose, linked to an anthocyanidin. Despite differences in colour from orange to black, the berries in the genus Sambucus are characterized by pigments 14-16, or by other cyanidin derivatives containing xylose. Simple anthocyanin 3-monoglucosides (mainly 2) dominate in berries of Lonicera species, while the examined species of Viburnum contained one or more cyanidin 3-glycoside, however, with differences in their anthocyanin pattern.
