%X This is a study of the chemical constituents of P. canadensis Moench. buds. In the study, the constituents of P.canadensis buds were separated using different chromatographic techniques, and their structures unveiled based on spectral analysis and physicochemical properties. Eleven compounds were isolated and identified as 1)pinostrobin; 2) chrysin; 3)kaempferol; 4)apigenin; 5)isorhamnetin; 6)isoferulic acid; 7)quercetin; 8)3-O-methyl quercetin; 9)caffeic acid; 10)galangin-7-glucoside; and 11) chrysin-7-glucoside. It is worth mentioning that 3), 5). 8), and 10) were isolated from Populus L. for the first time.
