摘 要:采用大孔树脂、MCI树脂、正相硅胶、Sephadex LH-20、制备薄层色谱和反相HPLC等多种色谱技术和方法,从板蓝根的水煎煮提取物中分离得到33个化合物,借助理化性质和波谱学数据分析,鉴定其结构为:(+)-去氢催吐罗芙木醇(1),(S)-(+)-脱落酸(2),(R)-4-羟基-4-[(R,E)-3-羟基丁-1-烯基]-5,5-二甲基环己烷-2-烯酮(3),环(L-苯丙-L-亮)二肽(4),环(L-苯丙-L-酪)二肽(5),环(L-酪-L-亮)二肽(6),环(L-脯-L-酪)二肽(7),(+)-3-羟基-1,2-二(4-羟基-3-甲氧基苯基)-1-丙酮(8),(+)-丁香树脂醇(9),(-)-(7R,7'R,8S,8'S)-4,4'-二羟基-3-甲氧基-7,9';9,7'-双环氧木脂素(10),(-)-皮树脂醇(11),(+)-(7R,7'R,8S,8'S)-新橄榄树脂素(12),(-)-5-甲氧基异落叶松树脂酚(13),1,3-二氢-2H-吲哚-2-酮(14),4-甲氧基-2,3-吲哚二酮(15),N-甲氧基二氢抗坏血酸原(16),尿蓝母(17),(-)-(S)-腈甲基-3-羟基氧吲哚(18),4'-羟基-7-甲氧基异黄酮(19),毛蕊异黄酮(20),豆甾-5-烯-3β-醇-7-酮(21),香草乙酮(22),4-羟基-3,5-二甲氧基苯乙酮(23),二氢松柏醇(24),3-甲氧基-4-羟基苯丙酸(25),3-羟基-1-(4-羟基苯基)丙-1-酮(26),3-羟基-1-(3-甲氧基-4-羟基苯基)丙-1-酮(27),对氨基苯甲酸(28),3-(4-羟基苯基)丙-1-醇(29),4-(2-羟乙基)苯酚(30),2-甲氧基-4-乙烯基苯酚(31),邻苯二酚(32)和4-戊烯酰胺(33)。这些化合物均为首次从板蓝根中分离得到。在初步体外抗病毒活性筛选中,异黄酮类化合物19对流感病毒A/汉防/359/95(H3N2)、单纯性疱疹病毒1型(HSV-1)和柯萨奇病毒B3型(Cox-B3)病毒株均显示有一定抑制活性,IC50分别为2.06,6.84,8.70μmol.L-1;在1.0×10-5mol.L-1下,其他化合物均未表现出活性。Thirty-three compounds were isolated from the root decoction of Isatis indigotica by using a combination of various chromatographic techniques including silica gel, maeroporous adsorbent resin, Sephadex LH-20, and reversed-phase HPLC. Their structures were elucidated by spectroscopic data as ( + )-dehydrovomifoliol (1), (S)-( + )-abscisic acid (2), vomifoliol (3), cyclo (L-Phe-L-Leu) (4), cyclo(L-Phe-L-Tyr) (5), cyclo(L-Tyr-L-Leu) (6), eyclo(L-Pro-L-Tyr) (7), evofolin B (8), ( + )-syringa- resinol (9), ( - ) -(7R,7'R,8S, 8'S) -4,4'-dihydroxy-3-methoxy-7,9' ;7' ,9-diepoxy-lignan (10), ( - ) -medioresinol ( 11 ), ( + )- (7R,7'R, 8S, 8 'S ) -neo-olivil ( 12 ), ( - ) -5-methoxyisolarieiresinol ( 13 ), 1,3-dihydro-2H-indol-2-one ( 14 ), isalexin ( 15 ), di- hydroneoascorbigen (16), indiean (17), ( - )- (S) -cyanomethyl-3-hydroxyoxindole (18), isoformononetein (19), calyeosin (20), stigamast-5-ene-3β-ol-7-one ( 21 ), aeetovanillone ( 22 ), 3,5-dimethoxy-4-hydroxyacetophenone ( 23 ), dihydroeoniferyl alcohol ( 24 ), dihyroferulic acid ( 25 ), 3-hydroxy-1 - ( 4-hydroxyphenyl ) propan-1 -one ( 26 ), β-hydroxypropiovanillone ( 27 ), 4-aminobenzoic acid (28), 3- (4-hydroxyphenyl) propan-1 -ol ( 29 ), 4- ( 2-hydroxyethyl ) phenol ( 30 ), 2-methoxy-4-vinylphenol ( 31 ), pyrocatechol (32), and 4-pentenamide (33). These compounds were isolated from the root of L indigotica for the first time. In preliminary in vitro assays, compound 19 showed activity against the influenza virus A/Hanfang/359/95 (H3N2 ), the herpes simplex virus 1 (HSV-1), and Coxsackie virus B3 (Cox-B3), with IC50 values of 2.06, 6. 84, and 8.70 μmol·L^-1, respectively, but other compounds were in- active at a concentration of 1.0 ×10^-5mol·L^-1.
