Özet

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-beta-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.
