Abstract

The β-glucosides of coumarinic and o-coumaric acids were detected in extracts of cotyledons, exocarps, and seedling leaves of the tonka bean. The existence of these compounds and the presence of a β-glucosidase having specificity for coumarinyl glucoside suggest that, the tonka bean synthesizes coumarin by a pathway similar to the one found in sweetclover.
