| Abstract: | Two novel diacylated and two known anthocyanins were isolated from violet flowers of Petunia hybrida cv Festival. The new anthocyanins are malvidin 3-O-(6-O-(4-O-(4-O-(6-O-feruloyl-beta-D-glucopyranosyl)-E-p-coumaroyl)-alpha-rhamnosyl)-beta-D-glucopyranoside)-5-beta-D-glucopyranoside and malvidin 3-O-(6-O-(4-O-(4-O-(6-O-E-p-coumaroyl-beta-D-glucopyranosyl)-E-p-coumaroyl)-alpha-rhamnosyl)-beta-D-glucopyranoside)-5-beta-D-glucopyranoside. The two known pigments are the 3-caffeoylglucosyl-p-coumaroylrutinoside-5-glucosides of malvidin and petunidin. |
