Direct Observation of Hydrangea Blue-Complex Composed of 3-O-Glucosyldelphinidin, Al(3+) and 5-O-Acylquinic Acid by ESI-Mass Spectrometry

The blue sepal color of hydrangea is due to a metal complex anthocyanin composed of 3-O-glucosyldelphinidin (1) and an aluminum ion with the co-pigments 5-O-caffeoylquinic acid (2) and/or 5-O-p-coumaroylquinic acid (3). The three components, namely anthocyanin, Al(3+) and 5-O-acylquinic acids, are e...
