目的:研究枸骨Ilex cornuta Lindl.ex Paxt.叶的黄酮类成分。方法:利用硅胶柱色谱和半制备高效液相色谱对枸骨的叶进行分离纯化, 利用光谱学手段结合理化性质鉴定其结构。结果:分离鉴定了9个黄酮类化合物, 分别为:山柰酚-3-O-β-D-吡喃葡萄糖(1→2)-α-L-吡喃阿拉伯糖苷(1),槲皮素-3-O-β-D-吡喃葡萄糖(1→2)-α-L-吡喃阿拉伯糖苷(2),异鼠李素-3-O-β-D-吡喃葡萄糖苷(3),金丝桃苷(4),3’-甲氧基大豆苷(5),异鼠李素(6),芒柄花素(7),山柰酚(8),槲皮素(9).结论:化合物1为新的黄酮类成分。
Objective: To study the flavonoids of Ilex cornuta Lindl. Ex Paxt. Methods: The leaves of Citrus reticulata were separated and purified by silica gel column chromatography and semi-preparative high performance liquid chromatography (HPLC). Their structures were identified by spectroscopic methods and physical and chemical properties. Results: Nine flavonoids were isolated and identified as kaempferol-3-O-β-D-glucopyranose (1 → 2) -α-L-arabinopyranoside -3-O-β-D-glucopyranoside (1 → 2) -α-L-arabinopyranoside (2), isorhamnetin-3-O-β-D-glucopyranoside (3) , Hyperin (4), 3’-methoxy daidzin (5), isorhamnetin (6), formononetin (7), kaempferol (8), quercetin (9) Conclusion: Compound 1 is a new flavonoid component.
