title: Dihydrochalcones and coumarins of Esenbeckia grandiflora subsp. brevipetiolata.
abstract: Six furoquinolines and five coumarins have been isolated from the roots of Esenbeckia grandiflora subsp. brevipetiolata. The leaves yielded two dihydrochalcones and two flavonol rhamnosides. One of the coumarins (5-senecioyl-xanthotoxin) and the dihydrochalcones are novel compounds and their structures were elucidated by spectroscopic methods. The comparison with the dihydrochalcones previously isolated from another subspecies, E. grandiflora subsp. grandiflora is also provided.
