摘要 采用硅胶、Sephadex LH-20等多种材料进行分离纯化,通过理化方法和波谱分析进行结构鉴定,从桂花果实醇提溶液的乙酸乙酯萃取部分,分离并鉴定了23个化合物,分别为尼克酰胺(1),D-阿洛醇(2),5-羟甲基-2-呋喃甲醛(3),乙酰氧基齐墩果酸(4),苯甲酸(5),麦角甾-7,22-二烯-3-酮(6),β-谷甾醇(7),borreriagenin(8),麦角甾-7,22-二烯-3β,5α,6β-三醇(9),C-veratroylglycol(10),甲基-2-O-β-吡喃葡糖基苯甲酸(11),3',7-二羟基-4'-甲氧基异黄酮(12),7-羟基香豆素(13),咖啡酸甲酯(14),齐墩果酸(15),(-)-襄五脂素(16),莳萝油脑(17),3β,5α,9α-三羟基-麦角甾-7,22-二烯-6-酮(18),2α-羟基齐墩果酸(19),桦木酸(20),白桦脂醇(21),3,3'-Bisdemethylpinoresinol(22),羽扇豆醇(23)。所有化合物在桂花果实中均为首次分离;除化合物4,7,15,19,23外,其余化合物在此种植物中为首次分离。 By Silica gel, Sephadex LH-20 and other materials for isolation and purification and by physicochemical methods and spectral analysis for structural identification, 23 compounds were isolated and identified from ethyl acetate portion of alcohol extract solution of Osmanthus fragrans fruits. Their structures were identified as nicotinamide(1), D-allitol(2), 5-hydroxymethyl-2-furancarboxaldehyde (3), acetyloleanolic acid ( 4 ), benzoic acid ( 5 ), ergosta-7,22 -dien-3-one ( 6),β-sitosterol ( 7 ), borreriagenin ( 8 ), cerevistero ( 9 ), c-veratroylglycol ( 10), methyl-2 -O-/3-glucopyranosylbenzoate ( 11 ), 3', 7 -dihydroxy-4'-methoxyisoflavon ( 12 ), umbelliferone( 13), caffeic acid methyl ester( 14 ), oleanolic acid ( 15 ), ( - ) -chicanine ( 16 ), dillapiol ( 17 ), 3β,5a, 9a-trihydrexyergosta-7- 22-dien-6-one ( 18), 2a-hydroxy-oleanolic acid ( 19), betulinic acid (20), betulin (21), 3, 3'-bisdemethylpinoresinol (22), and lupeol (23). All compounds were isolated from the osmanthus fruit for the first time. Except for compounds 4, 7, 15, 19, 23, the rest ones were isolated from the this plant for the first time.
