霞草中化学成分的分离与结构鉴定

Isolation and structure identification of the chemical constituents from Gypsophila oldhamiana

摘要: 目的研究石竹科植物霞草(Gypsophila oldhamiana Miq.)根部的化学成分。方法利用柱色谱技术进行分离纯化，根据理化性质和现代波谱技术并辅以化学方法进行结构鉴定。结果从霞草根部甲醇提取物的石油醚部位和乙酸乙酯部位分得5个化合物。分别鉴定为：菠菜甾醇3-O-β-D葡糖苷(I)，咖啡酸二十四碳脂肪醇酯(II)，蔗糖(III)， β-谷甾醇(IV)，胡萝卜苷(V)。结论化合物II为新化合物，化合物I为首次从该植物中分得。

Abstract: AimTo study the constituents of the root of Gypsophila oldhamiana Miq. Methods Silica gel column chromatographic technique was used for the isolation and purification of compounds. The structures were elucidated on the basis of spectral data and chemical evidences. ResultsFive compounds were obtained and identified as the β-D-glucoside of α-spinasterol (I), tetracosyl caffeate (II), sucrose (III), β-sitosterol (IV) and daucosterol (V). ConclusionCompound II is a new compound. Compound I was isolated from this plant for the first time.
