摘　　要：目的研究旱柳Salix matsudana叶的化学成分。方法运用多种柱色谱方法分离纯化,通过理化性质及波谱分析技术鉴定化合物的结构。结果从旱柳叶的水提物中分离得到6个化合物,分别鉴定为5,7-二羟基色原酮-5-O-β-D-葡萄糖苷（1）、5,7-二羟基色原酮（2）、（2-羟苯基）-O-β-D-吡喃葡萄糖苷（3）、香草酸-4-O-β-D-葡萄糖苷（4）、环（缬氨酸-脯氨酸）（5）、没食子酸（6）。结论化合物1为新化合物,命名为旱柳苷A,化合物2-6为首次从该植物中分离得到。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.
