Acylated anthocyanins in inflorescence of spider flower (Cleome hassleriana)

Five anthocyanins, cyanidin 3-(2 ''-(6'''-caffeoyl-beta-glucopyranosyl)-6 ''-(E-p-coumaroyl)-beta-glucopyranoside)-5-beta-glucopyranoside, cyanidin 3-(2 ''-(6'''-E-sinapoyl-beta-glucopyranosyl)-6 ''-(E-p-coumaroyl)-beta-glucopyranoside)-5-beta-glucopyranoside, cyanidin 3-(2 ''-(6'''-feroyl-beta-glucopyranosyl)-6 ''-(E-p-coumaroyl)-beta-glucopyranoside)-5-beta-glucopyranoside, pelargonidin 3-(2 ''-(6'''-E-sinapoyl-beta-glucopyranosyl)-6 ''-(E-p-coumaroyl)-beta-glucopyranoside)-5-beta-glucopyranoside, and pelargonidin 3-(2 ''-(6'''-E-p-coumaroyl-beta-glucopyranosyl)-6 ''-(E-p-coumaroyl)-beta-glucopyranoside)-5-beta-glucopyranoside, together with five known anthocyanins have been identified in flowers of Cleome hassleriana Queen line. One monoacylated and four diacylated cyanidin 3-sophoroside-5-glucosides were identified as the main anthocyanins in flowers with mauve colouration, while a homologous glycosidic pattern based on pelargonidin was found in the five main anthocyanins from flowers with pink colouration. The anthocyanins identified in C. hassleriana share the same glycosidic pattern as anthocyanins isolated from the genera Raphanus, Brassica and Iberis in the sister family Brassicaceae.
