Fluorescence is measured on unhydrolyzed and hydrolyzed plant extracts, with and without prior ultraviolet treatment. Readings permit direct determination of free σ-hydroxycinnamic acid (σ-HCA), free trans-σ-HCA, total σ-HCA, and total trans-σ-HCA. Levels of bound trans-σ-HCA and free and bound cis-σ-HCA are calculated by appropriate subtraction.
