摘 要:目的:研究花生壳化学成分。方法:利用硅胶、Sephadex LH-20等色谱方法及重结晶分离化合物,利用MS、1H-NMR、13C-NMR等波谱方法鉴定化合物结构。结果:从花生壳90%乙醇提取物中分离得到12个化合物,分别鉴定为:木犀草素(1)、香叶木素(2)、5,7,3',4'-tetrahydroxy-8-prenylflavone(3)、5,7,3'-trihydroxy-4'-methoxy-8-prenylflavone(4)、圣草酚(5)、racemoflavone(6)、大风子素(7)、5,7-二羟基色原酮(8)、5-羟基-色原酮-7-O-β-D-葡萄糖苷(9)、阿魏酸(10)、β-谷甾醇(11)、胡萝卜苷(12)。结论:其中,化合物2~4、6~7、9~10为首次从花生壳中分离得到。Objective:To investigate the chemical constituents of peanut hull. Methods:Several chromatography methods such as silica gel and Sephadex LH-20 combined with recrystallization were applied to isolate the compounds. Based on spectrum technologies ( MS, 1H-NMR and 13 C-NMR) and physieo-ehemical methods, structures of isolated compounds were identified. Results : Twelve com- pounds were isolated and elucidated as luteolin ( 1 ), diosmetin ( 2 ), 5,7,3', 4'-tetrahydroxy-8-prenylflavone ( 3 ), 5,7,3'-trihydroxy-4'- methoxy-8-prenylflavone ( 4 ), eriodicrtyol ( 5 ), racemoflavone ( 6 ), hydnocarpin ( 7 ), 5,7-dihydroxy chromone ( 8 ), 5-hydroxy-chromone- 7-O-β-D-glucoside ( 9 ), ferulic acid ( 10 ),/3-sitosterol ( 11 ) and daucosterol ( 12 ). Conclusion : Except compounds 1,5 and 8, all com- pounds are obtained from peanut hull for the first time.
