摘 要:绵枣儿来源于风信子科植物绵枣儿Scilla scilloides(Lindl.)Druce的鳞茎。本研究采用HPD100大孔树脂、硅胶、SephadexLH=20、ODS柱色谱和半制备HPLC等方法,从采自河南信阳的绵枣儿中分离出17个化合物;根据化合物的理化性质和波谱数据,分别鉴定为2-羟基-7-甲氧基绵枣儿素(1),绵枣儿素(2),5,7-dihydroxy-3,4'-dimethoxyspiro{2H-1-benzopyr·an-7'-bicyclo4.2.0octa1,3,5-trien}-4-one(3),socialinone(4),4-甲基白藜芦醇(5),(E)-白藜芦醇(6),scillavoneA(7),3,9-dihydroeucomnalin(8),3-(3-羟基4-甲氧基苄基)-5,7-二羟基苯并二氢吡喃-4-酮(9),(3R)-5,7,3’.tfihydroxy-4'-methoxyspiro{2H-1-benzopyran-7’bicyclo4,2,0octa1,3,5-trien}-4-one(10),scillabeneA(11),2-羟基绵枣儿素(12),3-(4-羟基苄基)-5,7-二羟基苯并二氢吡喃4-酮(13),3-(4-羟基亚苄基)-5,7-二羟基苯并二氢吡喃4-酮(14),3-(4-羟基苄基)-5-羟基-7,8-二甲氧基苯并二氢吡喃4-酮(15),3-(4-羟基苄基)-5-羟基-6,7-二甲氧基苯并二氢吡喃4-酮(16),3-(4-羟基苄基)-5,8.二羟基-7-甲氧基苯并二氢吡喃4-酮(17),其中化合物3,4,6,9,13和15-17为首次从绵枣儿植物中分离得到。Mian-Zao-Er was collected from the bulbs of Scilla scilloides (Lindl.) Druce, belonging to the Hyacinthaceae fami- ly. 17 compounds were obtained using various column ehromatographies on maeroporus resin (HPD100), silica gel, Sephadex LH-20 and ODS, as well as semi-preparative HPLC. Their structures were elucidated on the basis of physicoehemieal properties and spectral data as 2 -hydroxy-7-methoxyscillascillin ( 1 ), seillaseillin (2), 5,7-dihydroxy-3 ', 4 '-dimethoxyspiro { 2 H-1 -benzopyran-7'-bicyclo [ 4. 2.0 ] octa[ 1,3,5 ] -trien t -4-one (3) , soeialinone (4) , 4-methylresveratrol (5) , (E) -resveratrol (6) , scillavoneA (7) , 3,9-di- hydroeucomnalin ( 8 ), 3-( 3-hydroxy-4-methoxybenzyl ) -5,7-dihydroxychroman-4-one ( 9 ), ( 3 R ) -5,7,3 '-trihydroxy-4'-methoxyspiro { 2H-l-benzopyran-7'-bieyclo[4,2,0 ] octa[ 1,3,5 ]-trien } -4-one ( 10 ), seillabene A ( 11 ), 2-hydroxyscillaseillin ( 12 ), 3-( 4- hydroxybenzyl) -5,7 -dihydroxychroman-4-one ( 13 ), 3- ( 4 -hydroxybenzylidene ) -5,7-dihydroxychroman-4 -one ( 14 ), 3- ( 4 -hydroxy- benzyl)-5-hydroxy-7,8-dimethoxyehroman-4-one ( 15 ), 3-( 4-hydroxybenzyl )-5-hydroxy-6, 7-dimethoxychroman-4-one ( 16 ), and 3-(4-hydroxybenzyl)-5,8-hydroxy-7-methoxyehroman-4-one (17). Among them, compounds 3, 4, 6, 9, 13 and 15-17 were isolated from this plant for the first time.
