Structures of two diacylated anthocyanins from Petunia hybrida cv. Surfinia Violet Mini

Two novel diacylated anthocyanins and two known monoacylated anthocyanins were isolated from violet petals of Petunia hybrida cv. Surfinia Violet Mini. Their structures were elucidated by spectral methods. The major novel pigment was identified as malvidin 3- O -(6- O -(4- O -(4- O -(6- O -caffeoyl- β -d-glucopyranosyl)- p -coumaroyl)- α -l-rhamnosyl)- β -d-glucopyranoside)-5- O - β -d-glucopyranoside and the minor novel pigment was determined as malvidin 3- O -(6- O -(4- O -(4- O -(6- O -caffeoyl- β -d-glucopyranosyl)-caffeoyl)- α -l-rhamnosyl)- β -d-glucopyranoside)-5- O - β - d-glucopyranoside.
