摘要 目的:研究核桃种皮的化学成分。方法:采用硅胶,MCI凝胶,Sephadex LH-20柱色谱和制备高效液相色谱进行单体化合物分离,采用EI-MS,FAB-MS,NMR对化合物结构进行鉴定,并采用气质联用对核桃种皮中的挥发性成分进行分析。结果:通过经典色谱方法分离得到15个化合物,经光谱分析方法分别鉴定为红景天苷(1),(6S,9S)-长寿花糖苷(2),(6S,9R)-长寿花糖苷(3),blumenol C glucoside(4),byzantionoside B(5),5-羟基-2-甲氧基-1,4-萘醌(6),没食子酸(7),甘油-1-(9Z-十八碳烯酯)-2-(9Z,12Z-十八碳二烯酯)-3-(9Z,12Z,15Z-十八碳三烯酯)(8),甘油-1,2,3-三-(9Z,12Z-十八碳二烯酯)(9),甘油-1,2,3-三-(9Z,12Z,15Z-十八碳三烯酯)(10),甘油-1-十六碳烷酯-2,3-二-(9Z,12Z-十八碳二烯酯)(11),并通过GC-MS指认了35个化合物。结论:化合物1~5,8~11首次核桃中分离得到,并首次采用GC-MS研究了核桃种皮中的挥发性成分。 Fifteen compounds were isolated from the seed coat of Juglans regia by silica gel, MCI gel and Sephadex LH-20 gel column chromatography, as well as high preparative performance liquid chromatography. Their structures were identified as salidroside ( 1), (6S, 9S) -roseoside (2), (6S, 9R) -roseoside (3), blumenol C glucoside (4), byzantionoside B (5), 5-hydroxy-2-methoxy-1, 4-naphthoquinone(6), gallic acid(7), glycerol 1-(9Z-octadecenoate)-2-(9Z, 12Z-octadecadienoate)-3-(9Z, 12Z, 15Z-octadecatrienoate) (8), glycerol 1,2, 3-tri-(9Z, 12Z-octadecadienoate)(9), glycerol 1,2, 3-tri-(9Z, 12Z, 15Z-octadecatrienoate)(10), glycerol 1-hexadecanoate-2, 3-di-(9Z, 12Z-octadecadienoate) (11) on the basis of EI-MS, FAB-MS and NMR spectra. Moreover, 35 volatile compounds were identified by GC-MS.
