Abstract

Chalcones and aurones, which are often referred to as the “anthochlor” pigments because many turn red on contact with alkali, are relatively rare types of flavonoids [1]. Detailed spectral analyses, in particular of synthetic chalcones and aurones, have been published elsewhere [25], but for completeness a number have been included here. The UV spectra of both chalcones and aurones are characterized by an intense Band I and a diminished Band II absorption.
