摘　　要：The aim of this study is to isolate and identify the chemical compounds in ethanol extract of Cyclocarya paliurus.Some purification and analysis techniques like silica gel,D101-macroporous adsorptive resins,and Sephadex LH-20 column chromatographies as well as high-performance liquid chromatography were used to isolate and analyze the compounds from ethanol extract of Cyclocarya paliurus.The structures of these constituents were identified by spectroscopic techniques such as nuclear magnetic resonance and high-resolution mass spectrometries.Twenty-eight compounds,including flavonoids and their glycoside,carbohydrate,coumarin and organic acid,were isolated from ethyl acetate and n-butanol fractions in ethanol extract of Cyclocarya paliurus,and they were identified as kaempferol(1),coumestrol(2),kaempferol 3-O-β-D-glucoside(3),methyl caffeoylquinic acid(4),coptichic aldehyde(5),schizandriside(6),kaempferol 3-O-α-L-rhamnoside(7),3-caffeoylquinic acid ethyl ester(8),quercetin(9),luteolin(10),protocatechuic acid(11),kaempferol-3-O-α-L-furan arabinose(12),trans-p-hydroxy-cinnamic acid(13),α-D-glucopyranosido-β-D-fructofuranoside,sucrose(14),peucedanol(15),chlorogenic acid(16),pyridoxine(17),quercetin-3-O-β-D-glucuronide(18),kaempferol-3-O-β-D-glucuronide(19),isoquercitrin(20),mururin A(21),citroside A(22),benzyl-6-O-α-L-arabinofuranosyl-β-D-glucopyranoside(23),(+)-(6S,9R)-9-O-β-D-glucopyranosyl-6-hydroxy-3-O-α-ionol(24),myricetin-3-O-β-D-glucopyranoside(25),(4R)-4-(3-Oxo-1-buten-1-ylidene)-3α,5,5-trimethylcyclohexane-1α,3β-diol(26),quercetin-3-O-α-L-rhamnopyranosyl(27)and 3,5-O-dicaffeoylquinic acid(28).Compounds 2,5,6,15,21,22,23,24,26 and 28 were isolated from Cyclocarya paliurus for the first time.本研究旨在对青钱柳叶醇提物的乙酸乙酯和正丁醇萃取部位的化学成分进行提取和鉴定。运用硅胶、D101大孔吸附树脂、Sephadex LH-20等柱色谱和高效液相色谱分离和纯化青钱柳叶醇提物的化学成分,并运用核磁共振、高分辨质谱等谱学技术鉴定所得化合物的结构。从青钱柳叶醇提物的乙酸乙酯和正丁醇萃取部位分离得到黄酮及其苷类、糖类、香豆素和有机酸等类化合物28个,分别鉴定为山奈酚(1)、拟雌内酯(2)、山柰酚-3-O-β-D-葡萄糖苷(3)、绿原酸甲酯(4)、黄连醛碱(5)、五味子苷(6)、山柰酚-3-O-α-L-鼠李糖苷(7)、绿原酸乙酯(8)、槲皮素(9)、木犀草素(10)、原儿茶酸(11)、山奈酚-3-O-α-L-呋喃阿拉伯糖(12)、反式对羟基肉桂酸(13)、蔗糖(14)、彼西丹醇(15)、绿原酸(16)、吡哆醇(17)、槲皮素-3-O-β-D-葡萄糖醛酸苷(18)、山奈酚-3-O-β-D-葡萄糖醛酸苷(19)、异槲皮苷(20)、mururin A(21)、柑橘苷A(22)、苄基-6-O-α-L-阿拉伯呋喃糖基-β-D-吡喃葡萄糖苷(23)、(+)-(6S,9R)-9-O-β-D-吡喃葡萄糖苷-6-羟基-3-O-α-紫罗兰醇(24)、杨梅素-3-O-β-D-葡萄糖苷(25)、蚱蜢酮(26)、槲皮素-3-O-α-L-鼠李糖苷(27)和3,5-O-二咖啡酰奎尼酸(28)。其中化合物2,5,6,15,21,22,23,24,26和28均系首次从青钱柳叶中分离得到。
