摘要 目的: 对苦木科苦树属植物苦树Picrasma quassioides的化学成分进行研究。 方法 :采用各种柱色谱和重结晶等技术进行分离纯化,综合运用紫外光谱(UV)、红外光谱(IR)、质谱(MS)及核磁共振光谱(1H-NMR,13C-NMR)等现代波谱学方法和技术进行化合物的结构鉴定。 结果 :从苦树中鉴定得到了14个化合物,分别为高丽槐素-3-O-β-D-葡萄糖苷( 1 ),maackiain( 2 ),3',7-二羟基-4-甲氧基异黄酮( 3 ),7-羟基香豆素( 4 ),大黄素( 5 ),nigakilactone F( 6 ),picrasin B( 7 ),picraqualide B( 8 ),4-甲氧基-5-羟基-铁屎米-6-酮( 9 ),4, 5-二甲氧基-铁屎米-6-酮( 10 ),5-甲氧基-铁屎米-6-酮( 11 ),11-羟基-铁屎米-6-酮( 12 ),1-甲氧甲酰基-β-咔巴啉( 13 ),1-羟甲基-β-咔巴啉( 14 )。 结论 :化合物 1~5 在苦树属中为首次报道。 To study the chemical constituents of Picrasma quassioides. The chemical constituents were isolated and purified by chromatographic methods over Sephadex LH-20 and silica gel column, and structurally elucidated by spectral analysis, including UV, IR, MS, 1H-NMR, 13C-NMR. Fourteen compounds were obtained and identified as trifolirhizin ( 1 ), maackiain ( 2 ), 3', 7-dihydroxy-4'-methoxylisoflavone ( 3 ), umbelliferone ( 4 ), emodin( 5 ), nigakilactone F ( 6 ), picrasin B ( 7 ),picraqualide B ( 8 ),4-methoxy-5-hydroxycanthin-6-one ( 9 ), 4,5-dimethoxycanthin-6-one ( 10 ),5-methoxycanthin-6-one ( 11 ),11-hydroxycanthin-6-one ( 12 ),1-methoxycarbonyl-β-carboline ( 13 ), 1-hydroxymethyl-β-carboline ( 14 ). Compounds 1-5 are reported from the first time for the genus Pricrasma.
