Objective To study the chemical constituents from the leaves of Salix matsudana. Methods The chemical constitunents were isolated by various column chromatographic methods. The structures of the compounds were elucidated on the basis of physiochemical properties and spectral analyses. Results Six compounds were named as 5-β-D-glucosyloxy-7-hydroxychromone (1), 5, 7-dihydroxychromone (2), (2-hydroxyphenzyl)-O-β-D-glucopyranoside (3), vanillic acid-4-O-β-D-glucoside (4), cyclo (val-pro) (5), and gallic acid (6). Conclusion Compound 1 is a new compound named matsudoside A, compounds 2—6 are obtained from this plant for the first time.
