Two diacylated malvidin glycosides from Petunia hybrida flowers

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-β- d -glucopyranosyl)- E - p -coumaroyl)-α-rhamnosyl)-β- d -glucopyranoside)-5-β- d -glucopyranoside and malvidin 3- O -(6- O -(4- O -(4- O -(6- O - E - p -coumaroyl-β- d -glucopyranosyl)- E - p -coumaroyl)-α-rhamnosyl)-β- d -glucopyranoside)-5-β- d -glucopyranoside. The two known pigments are the 3-caffeoylglucosyl- p -coumaroylrutinoside-5-glucosides of malvidin and petunidin.
