Two new eudesmane derivatives were isolated from the leaves and flowers of Verbesina virginica, along with the known 6-O-β-E-p-coumaroyl-4α-hydroxyeudesmane (1). Their structures were determined as 6-O-β-Z-p-coumaroyl-4α-hydroxyeudesmane (2) and 6-O-α-E-p-coumaroyl-1β-4α-dihydroxyeudesrnane (3) by spectroscopic methods.
