Seven acylated anthocyanins in the blue flowers of Hyacinthus orientalis.
Two novel anthocyanins, delphinidin 3-O-(6-O-cis-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta-D -glucoside) and petunidin 3-O-(6-O-trans-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta -D-glucoside) , were isolated from the blue flowers of Hyacinthus orientalis cv. Delft Blue. Five known acylated anthocyanins, namely, delphinidin 3-O-(6-O-trans-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-beta-D-gluco side), delphinidin 3-O-(6-O-trans-caffeoyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta-D- glucoside), delphinidin 3-O-(6-O-trans-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta -D-glucoside) , cyanidin 3-O-(6-O-trans-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta -D-glucoside) and pelargonidin 3-O-(6-O-trans-p-coumaroyl-beta-D-glucoside)-5-O-(6-O-malonyl-beta -D-glucoside) , were also isolated from these flowers. The complete structure of each compound was unambiguously determined by one- and two-dimensional NMR techniques.
