Acylated anthocyanins from Ipomoea cairica

Four new acylated anthocyanins have been isolated from flowers of Ipomoea cairica (L.) Sweet. Pigments I and II were characterized as isomers of cyanidin-3-(p-coumaryl-caffeyl-sophoroside)-5-glucoside, IIIb as cyanidin-3-(dicaffeyl-sophoroside)-5-glucoside and IV as cyanidin-3-(caffeyl-sophoroside)-...
