栀子化学成分(Ⅳ)

Chemical Components of Gardeniae Fructus( Ⅳ)

目的：研究栀子的干燥成熟果实中的化学成分。方法：采用各种柱色谱方法分离纯化,通过理化常数测定和光谱分析鉴定化合物的结构。结果：从栀子的果实中分离鉴定了10个化合物,分别为6″-O-[（E）-p-香豆酰基]京尼平龙胆二糖苷（1）,3-O-咖啡酰基-4-O-芥子酰基奎宁酸（2）,6″-O-反式-芥子酰基京尼平龙胆二糖苷（3）,绿原酸（4）,3-甲氧基-4-羟基苯酚（5）,东莨菪内酯（6）,滨蒿内酯（7）,2-（3-甲氧基-4-羟基苯）乙基-β-D-呋喃芹糖氧基-（1→6）-β-D-葡萄糖苷（8）,中脂素（9）,5＇-甲氧基异落叶松脂醇-3α-O-β-D-葡萄糖苷（10）。结论：化合物5~10为首次从该植物中分离得到。

Objective： To investigate the chemical components of Gardenia jasminoides. Method： The isolation and purification of components were performed using various column chromatography,and the chemical structures were identified by physiochemical constant determination and spectral analysis. Result： Ten compounds were isolated and identified as 6″-O- [（ E）-p-coumaroyl ]-gentiobiosylgenipin（ 1）, 3-O-caffeoyl-4-Osinapoylquinic acid（ 2）,6″-O-trans-sinapoylgenipin gentiobioside（ 3）,chlorogenic acid（ 4）,3-methoxy-4-hydroxyphenol（ 5）,scopoletin（ 6）,scoparone（ 7）,3-methoxyosmanthuside H（ 8）,medioresinol（ 9）,5＇-methoxyisolariciresinol-3α-O-β-D-gluco pyranoside（ 10）. Conclusion： Compounds 5-10 were isolated from this plant for the first time.
