An acetylated anthocyanin from the blue petals of Salvia uliginosa

The structure of a new anthocyanin from Salvia uliginosa petals has been identified as delphinidin 3-O-[6-O-(p-coumaroyl)-β-d-glucopyranoside]-5-O-[4-O-acetyl-6-O-malonyl-β-d-glucopyranoside] using mass spectroscopy and NMR. This compound constitutes the anthocyanin component of the pigment responsible for blue flower colour in S. uliginosa.
