Abstract
A blue violet pigment was isolated in a crystalline state from the flowers ofPlatycodon grandiflorum A. DC. by the use of neutral solvents. The absorption spectrum of this pigment in buffer solution (pH 4.5) was almost identical with that of an intact tissue. The essential component of this pigment is platyconin, i.e., delphinidin 3-dicaffeoylrutinosido-5-glucoside.
