Phenolic Compounds from Scorzonera tomentosa L.

From the subaerial parts of S. tomentosa L. (Asteraceae), two new dihydroisocoumarins, compounds 1 and 2, a new phthalide, 3, and a new stilbene derivative, 4, were isolated, together with four known compounds, (±)‐hydrangenol (5), (−)‐hydrangenol 4′‐O‐β‐glucoside (6), (±)‐hydramacrophyllol A (7), and (±)‐hydramacrophyllol B (8). All secondary metabolites were identified on the basis of physicochemical, spectroscopic, and mass‐spectrometric data. The known compounds 5–8 were isolated for the first time from this species.
