Cover Story: The original color of hydrangea sepal is blue, but the color is readily changed according to the environmental conditions, such as the acidity of soils. Chemical studies on sepal coloration have been performed form the early 20th century, but until now the only identified components essential for the blue coloration were delphinidin 3-glucoside, 5-O-acylquinic acids, and Al3+. We reproduced the hydrangea blue complex and analyzed it by ESI–mass spectrometry. We determined that the complex is a combination of anthocyanin, co-pigment, and Al3+ in the ratio of 1:1:1.
