摘要 通过MCI树脂、Sephadex LH-20和反相HPLC等多种色谱分离方法相结合,从山鸡椒乙醇提取物中的水溶性部位中分离得到25个芳香苷和3个紫罗兰苷类成分,经MS和NMR等波谱技术分别鉴定为(7S,8R)-去氢二松柏醇-4,9'-二-O-β-D-吡喃葡萄糖苷(1),(7S,8R)-5-甲氧基二氢去氢二愈创木基醇-4-O-β-D-吡喃葡萄糖苷(2),(7S,8R)-urolignoside(3),(7R,8S)-二氢去氢二愈创木基醇-4'-O-β-D-吡喃葡萄糖苷(4),(7S,8R)-二氢去氢二愈创木基醇-9-O-β-D-吡喃葡萄糖基(1→2)-O-β-D-吡喃葡萄糖苷(saposide B)(5),lanicepside A(6),罗汉脂素-4-O-β-D-吡喃葡萄糖苷(7),4-O-甲基罗汉脂素-4'-O-β-D-吡喃葡萄糖苷(tyraxjaponoside B)(8),(+)-南烛木树脂酚-9'-O-β-D-吡喃葡萄糖苷(9),(-)-(2R)-1-O-β-D-吡喃葡萄糖基2-{2,6-二甲氧基-4-[1-(E)-丙烯3-醇]苯氧基}丙烷-3-醇(alaschanisoside A)(10),紫丁香苷(syringin)(11),psoralenoside(12),isopsoralenoside(13),东莨菪苷(scopolin)(14),2,6-二甲氧基-4-羟基苯酚-1-O-β-D-吡喃葡萄糖苷(15),3-羟基-4,5-二甲氧基苯酚-β-D-吡喃葡萄糖苷(16),2-(3,4-二羟基苯基)-乙基-β-D-吡喃葡萄糖苷(17),2-(4-羟基苯基)-乙基-β-D-吡喃葡萄糖苷(18),(+)-儿茶素-7-O-β-D-吡喃葡萄糖苷(19),3'-甲氧基表儿茶素-7-O-β-D-吡喃葡萄糖苷(20),山奈酚-3,7-α-L-二鼠李糖苷(kaempferitrin)(21),槲皮素-3-O-α-L-鼠李糖苷(22),山奈酚-3-O-β-D-吡喃葡萄糖苷(23),山奈酚-3-O-β-D-吡喃葡萄糖基(1→2)-β-D-吡喃半乳糖苷-7-O-α-L-鼠李糖苷(24),槲皮素-3-O-α-L-鼠李糖基(1→6)-O-β-D-吡喃葡萄糖基(1→3)-O-α-L-鼠李糖基(1→2)-O-β-D-吡喃葡萄糖苷(25),staphylionoside D(26),吐叶醇-9-O-β-D-吡喃葡萄糖苷(27),二氢吐叶醇-O-β-D-吡喃葡萄糖苷(28),其中化合物1~21,24~28均为首次从该属植物中发现。 Twenty five known aromatic glycosides (1-25) and three known sesquiterpene glycosides (26-28) have been isolated from the twigs of Litsea cubeba by using various chromatographic techniques. Their structures were identified by spectroscopic data anal- ysis (MS, IR, 1D and 2D NMR) as (7S,8R)-dehydrodiconiferyl alcohol 4,9'-di-O-β-D-glucopyranoside(1), (7S,8R)-5-methoxydi- hydrodehydrodiconiferyl alcohol 4-O-β-D-glucopyranoside (2) , (7S, 8R) -urolignoside (3), (7R, 8S) -dihydrodehydrodiconiferyl alcohol 4-O-β-D-glucopyranoside (4) , saposide B (5), lanicepside A (6) , matairesinol-4-O-β-D-glucopyranoside (7) , tyraxjaponoside B (8) , ( + ) -lyoniresinol-9'-O-β-D-glucopyranoside ( 9 ) , alaschanisoside A ( 10 ) , syringin ( 11 ) , psoralenoside ( 12 ) , isopsoralenoside (13), scopolin(14), 2,6-dimethoxy-4-hydroxyphenol-1-O-β-D-glucopyranoside (15), 3-hydroxy-4,5-dimethoxyphenyl-β-D-glucopyr- anoside ( 16 ), 2-( 3,4-dihydroxyphenyl ) ethyl-β-D-glucopyrnoside ( 17 ), 2-( 4-dihydroxyphenyl ) ethyl-/β-D-giucopyranoside ( 18 ),( + ) -catechin-7-O-β-D-glucopyranoside (19) , 3 '-O-methylepicatechin-7-O-β-D-glucopyranoside (20) , kaempferitrin (21), querce- tin-3-O-α-L-rhamnopyranside ( 22 ), kaempferol-3-O-β-D-glueopyranoside ( 23 ), kaempferol 3-O-β-D-glueopyranosyl ( 1→2 ) -O-β-D- galactopyr anoside-7-O-α-L-rhamnopyranoside ( 24 ), quereetin 3-O-α-L-rhamnopyranosyl ( 1 --r6 ) -O-β-D-glueopyranosyl ( 1→3 ) -O-α- L-rhamnopyranosyl ( 1 --* 2 ) -O-β-D-glueopyranoside ( 25 ), staphylionoside D ( 26 ), vomifoliol 9-O-β-D-glucopyranoside ( 27 ), dihydrovomifoliol-O-β-D-glucopyranoside (28).
