Abstract

We have all experienced anthocyanins as a part of the natural beauty of the plant world. Anthocyanins provide a startling contrast to an otherwise green world producing the beauty of garden-variety flowers, wildflowers, and the blazing colors of many trees, bushes, and berries. We believe that anthocyanins deserve a more prominent role as models for engaging student interest in basic chemical principles. In recent years it has become common to use anthocyanins as pH indicators. We believe that chemistry teachers can capitalize further on the natural interest of students in anthocyanin pigments to design meaningful lessons involving chromatography and hydrolysis. This article focuses on the use of anthocyanins in chromatography and hydrolysis.
