Abstract
The structure elucidation of three metabolites herniarin (7-methoxy-2H-chromen-2-one, 1), phytoalexin (5-acetyl-6-hydroxy-2-(1-hydroxy-1-methylethyl)benzofuran, 2), and prestragol (3-(4′-methoxyphenyl)-prop-1,2-diol, 3) isolated from Artemisia dracunculus was determined on the basis of 1D, 2D NMR methods and by an X-ray crystallographic determination.
