✦ Synopsis
delphinidin. Cinerarin, which was isolated in 1974 by Yoshitama et al. 1 from blue flovers of garden cineraria, Senecip _cruentug DC., is one of the heavily acylated anthocyanins that are unusually stable in neutral aqueous solutions.2
They suggested its structure to be dicaffeyldelphinidin 3,7,3'-triglucoside, 3 but our study has disclosed that it is actually malonyltricaffeyldelphinidin tetraglucoside.
We have established its complete structure and stereochemistry as described below.
