Phytochemical examinations of the barks of Prunus species have led to the isolation of two new lignan xylosides, ssioriside (9) and prupaside (12). Compound 9 was obtained from Prunus (P.) ssiori and P. padus and 12 from P. padus. The spectroscopic data and chemical evidence allowed assignment of the structures of 9 and 12 as (8S, 8'S)-4, 4'-dihydroxy-3, 5, 3', 5'-tetramethoxy-8-8'-butyrolignan 9-O-β-D xylopyranoside and (8R, 7S, 8'R)-5, 5'-dimethoxylari-ciresinol 9'-O-β-D-xylopyranoside, respectively. Several previously reported compounds were also obtained and identified.
