Abstract

Extracts from leaves and first internodes ofSorghum bicolor catalyze the conversion offerulicacid to a β-β-coupled dimer, the dilactone dimer offerulicacid. The dilactone is then hydrolyzed, probably non-enzymatically, to a blue fluorescing compound, tentatively identified as a β-β-coupled dimer with at least one lactone ring opened to form a carboxylic acid. Both the initial enzymatic and the subsequent non-enzymatic steps are greater at pH 8 than pH 6. The most active preparation is a crude particulate fraction from leaves obtained by centrifugation at 37000 g; white light increases the amount of dimer formed
