The structures of two acylated betacyanins, lampranthin II from petals of Lampranthus peersii and L. sociorum and celostanin II from cell suspension cultures of Chenopodium rubrum, were elucidated as betanidin 5-O-[6'-O-(E)-feruloyl-β-glucoside] and betanidin 5-O-[2''-O-(E)-feruloyl-β-(1'',2')-glucuronosyl-β-glucoside].
