| 摘 要： | 从菝葜根茎中共分离得到3个新的二氢黄酮醇酰化糖苷(1～3)和1个已知的二氢黄酮醇苷(4),分别被鉴定为:(2R,3R)-二氢山萘酚3-氧-(6″-氧-乙酰基)-β-D-葡萄糖苷(1),(2R,3R)-二氢山萘酚3-氧-(2″-氧-乙酰基)-β-D-葡萄糖苷(2),(2R,3R)-二氢山萘酚3-氧-(3″-氧-乙酰基)-β-D-葡萄糖苷(3)及(2R,3R)-二氢山萘酚3-氧-β-D-葡萄糖苷(4)。其结构通过MS,1D NMR和2D NMR等光谱分析和化学方法确定。研究结果表明,二氢黄酮醇的酰化糖苷可能是菝葜属的特征成分。

| Abstract: | Three new flavanonol acetylated glycosides(1-3),together with a known flavanonol glycoside(4),were isolated from the rhizomes of Smilax china L.Their structures were elucidated on the basis of MS,1D and 2D NMR spectroscopic analysis and chemical evidence.The new compounds were characterized as(2R,3R)-dihydrokaempferol 3-O-(6′′-O-acetyl)-β-D-glucopyranoside(1),(2R,3R)-dihydrokaempferol 3-O-(2′′-O-acetyl)-β-D-glucopyranoside(2),and(2R,3R)-dihydrokaempferol 3-O-(3′′-O-acetyl)-β-D-glucopyranoside(3).The results indicate that flavanonol acetylated glycosides probably can serve as typical markers of the genus Smilax. |
