ACYLATED PELARGONIDIN 3,7-GLYCOSIDES FROM RED FLOWERS OF DELPHINIUM-HYBRIDUM

Six pelargonidin glycosides were isolated from the red flowers of Delp hinium hybridum cv ''Princess Caroline'' as major anthocyanins. These pigments were classified into two groups, based on the deacylglycoside s 3-rutinoside-7-glucoside and 3, 7-diglucoside. Three pigments belong ing to the former group are pelargonidin 3-rutinoside-7-glucoside, pel argonidin 3-rutinoside-7-[6-(p-hydroxybenzoyl)glucoside] and pelargoni din 3-rutinoside-7- [6-(4-(glucosyl)-p-hydroxybenzoyl)-glucoside]. The other three pigments are pelargonidin 3-[6-(malonyl)-glucoside]-7-glu coside, pelargonidin de-7-[6-(4-(glucosyl)-p-hydroxybenzoyl)-glucoside ] and pelargonidin ]-7-[6-(4-(glucosyl)-p-hydroxybenxoyl)-glucoside].
