چکیده
Abstract. The trimeric caffeic acid derivative pulcaffeate (1) was isolated from the organic crude extract of roots Bourreria pulchra (Boraginaceae). biosynthesis 1 appears to involve an intramolecular Diels-Alder reaction between a cyclohexa-1,3-diene intermediate, generated by oxidation aromatic ring cinnamic unit, and conjugated double bond unit. structure new metabolite elucidated through detailed analysis its 1H 13C NMR spectroscopic data. This is first report occurring in B. pulchra. Resumen.
