【摘要】 目的:研究旱柳叶的化学成分。方法:利用硅胶、Sephadex LH-20和MPLC等色谱方法进行化合物的分离纯化,根据化合物的理化性质、光谱数据进行结构鉴定。结果:从旱柳叶中分离得到8个化合物,分别鉴定为:β-谷甾醇(1)、香叶木素-7-O-β-D-葡萄糖苷(2)、(2S)-Helichrysin A(3)、(2R)-Helichrysin A(4)、木犀草苷(5)、水杨苷(6)、芹黄素-7-O-β-D-吡喃葡萄糖醛酸苷(7)、木犀草素-3’-甲醚-7-O-β-D-吡喃葡萄糖醛酸苷(8)。结论:其中,化合物1~4为首次从该植物中分离得到。更多还原

【Abstract】 Objective: To study the chemical constituents of the leaf of Salix matsudana. Methods: The chemical constituents were isolated by column chromatography on silica gel,Sephadex LH-20 and MPLC. Their structures were elucidated on the basis of spectral analysis. Results: Eight compounds were isolated and their structures were identified as β-Sitosterol( 1),5,7-Dihydroxychromone-7-O-β-D-glucopyranoside( 2),( 2S)-Helichrysin A( 3),( 2R)-Helichrysin A( 4),Luteolin-7-O-β-D-glucoside( 5),Salicin( 6),Apigenin-7-O-β-D-glucopyranside( 7),Lutelion-3’-methylether-7-O-β-D-glucopyranside( 8). Conclusion: Compounds 1 ~ 4 are isolated from this plant for the first time.更多还原
