Chemical transformations and spectral characteristics have enabled us to establish the structure and configurations of three coumarins: (+)-2',2'-dimethyl-3'β-hydroxy-3',4'-dihydropyrano(5',6':6,7)coumarin (I); (+)-4'β-hydroxy-5'β-(1-hydroxy-1-methylethyl)-4',5'-dihydrofuro(2',3':6,7)coumarin (II); and (+)-4'β-hydroxy-5'-(1-glucopyranosyloxy-1-methylethyl)-4',5'-dihydrofuro(2',3':6,7)coumarin (III) isolated from the roots of Smyrniopsis aucheri Karjag.This is the first time that these compounds, which have been called smyrinol, smyrindiol, and smyrindioloside, have been detected in nature.
