摘要
目的:沙生蜡菊花的化学成分研究。方法:采用多种色谱方法(硅胶柱色谱、ODS柱色谱和HPLC柱色谱)分离纯化,依据理化性质、波谱数据分析进行结构鉴定。结果:从沙生蜡菊花的甲醇提取物中分离得到7个黄酮类化合物,分别鉴定为槲皮素-3-O-β-D-吡喃葡萄糖苷(quercetin-3-O-β-D-glucopyranoside,1),芹菜素-7-D-β-D-龙胆二糖苷(apigenin7-O-β-D-gentiobioside,2),槲皮素3-O-芸香糖苷(quercetin3-O-rutinoside,3),芹菜素-7,4’-二-O-葡萄糖苷(apigenin-7,4'-O-β-D—glucopyra—nasideside,4),山柰酚-3,4’-二-O-葡萄糖苷(kaempferol-3,4'-di—O-β-D—glucopyranoside,5),槲皮素-3,3’-O-二葡萄糖(quercetin-3,3’-di-O-β-D—glucopyranaside,6),芹菜素-7-O-β-D-葡萄糖醛酸甲酯(apigenin-7-O-β—D—glucopyranosiduronic acid methyl ester,7)。结论:化合物2,4—7为首次从该属植物中分离得到。
Objective: To study the chemical constituents of Helichrysiflos syn. Method: The chemical constituents were isolated by various methods of isolation (silica gel, ODS column chromatography and HPLC ) and their structure were elucidated by the analysis of spectral data and chemical properties. Result: Seven flavone compounds were isolated from the MeOH extract of Helichrysi flos syn. The chemical structures were elucidated as quercetin-3-O-β-D-glucopyranoside (1), apigenin-7-O-β-D-gentiobioside (2), quercetin-3-O-rutinoside (3), apigenin-7,4'-di-O-β-D-glucopyranoside ( 4 ), kaempferol-3,4'-di-O-β-D-glucopyranoside ( 5 ), quercetin-3,3 '-di-O-β-D-glucopyranoside ( 6 ) , apigenin-7-O-β-D-glucopyranosiduronie acid methyl ester ( 7 ). Conclusion: Compounds 2, 4-7 were obtained from the genus Helichrysum. for the first time.
