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-dihydroxyeudesmane(3) by spectroscopic methods.
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-Zp -coumaroyl-4α-hydroxyeudesmane (2) and 6-O-α-Ep-coumaroyl-1β- 4α-dihydroxyeudesmane (3) by spectroscopic methods.
