Chemical investigation of the leaves of Populus euphratica Oliv. led to the isolation and identification of 13 compounds for the first time, among which 6'-O-cis-cinnamoylsalicin (1) and 6'-O-benzoylsalicortinol (2) were new compounds. The spectral data of 6'-O-trans-cinnamoylsalicin (3) and salicortinol (4) were reported for the first time. Their structures were elucidated on the basis of detailed spectroscopic analysis and comparisons with literature values.
Keywords: 6′-O-benzoylsalicortinol; 6′-O-cis-cinnamoylsalicin; Populus euphratica; Salicaceae; salicin derivative.
