Chemical Components of Gardeniae Fructus (Ⅳ)

摘要:

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.

Abstract:

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]-p-coumaroyl] -gentiobiosylgenipin (1), 3-O-caffeoyl-4-O-sinapoylquinic 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.
