杜仲叶黄酮类化学成分

Chemical Components of Flavonoids of Eucommiae Folium

摘要:

目的：研究杜仲叶中的黄酮类化学成分。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黄酮类化合物的结构。结果：从杜仲叶中分离并鉴定了8个黄酮类化合物，分别为槲皮素（1）、芦丁（2）、金丝桃苷（3）、槲皮苷（4）、异槲皮苷（5）、quercetin-3-O-sambubioside（6）、kaempherol-3-O-sambubioside（7）、quercetin-3-O-α-L-arabinopyranosyl-（1→2）-β-D-glucopyranoside（8）。结论：化合物4和7为首次从杜仲叶中分离得到。

Abstract:

Objective: To investigate the chemical components of flavonoids of Eucommiae Folium. Method: Various column chromatography were used in the isolation and purification, physiochemical constant determination and spectral analysis were adopted to determine the chemical structures of flavonoids. Result: Eight flavonoids were isolated from Eucommiae Folium,quercetin(1),rutin(2),hyperin(3),quercetin-3-O-α-L-rhamnopyloside(4),quercetin-3-O-β-D-glucopyranoside(5),quercetin-3-O-sambubioside(6),kaempherol-3-O-sambubioside(7),quercetin-3-O-α-L-arabinopyranosyl-(1→2)-β-D-glucopyranoside(8). Conclusion: 4 and 7 compounds were first isolated from this plant.
