摘    要:利用同时蒸馏萃取法(SDE)提取五灵中的挥发性组分。SE-54柱和PEG-20M柱上用气相色谱-质谱法分别检出122个和96个峰。其中有51种峰质谱检索结果相同,它们占总峰面积的56.3%。进一步用程序升温保留指数确认了其中33种化合物,占总峰面积的35.7%。含量较高的组分有:十二酸(7.00%),α-雪松醇(4.41%),四甲基吡嗪(4.10%),寸上酸(3.37%),1-(3-甲苯基)乙酮(2.53%),苯甲醛(2.42%),2-甲氧基苯酚(2.11%)。从化合物的种类来看,主要为醇类(10种),酮类(8种),醛类(8种),醛类(6种)、烯类(5种)、酸类(4种),酚类(4种)。

关 键 词:气相色谱-质谱联用  五灵脂  挥发性成分  气相色谱  程序升温保留指数定性  中药分析

Abstract:The volatile compounds of trogopterorum feces were collected by using a simultaneous distillation and extraction (SDE) equipment.The chemical composition of the enriched volatile was examined by means of capillary gas chromatography (GC) and combined GC mass spectrometry(MS). Fifty one constituenta of the volaitle were preliminarily identified by GC-MS,which amounted to 56.3% of the total peak area.Of these compounds,33 were further verified by measuring their temperature-programmed retention indexes(TPRI) or retention times.They amounted to 35.7% of the total peak areas.The main constituents of the volatile are dodecanoic acid(7.00%); alpha-cedrol (4.41%);pyrazine,tetramethyl-(4.10%); tetradecanoic acid(3.37%); ethanone,1-(3- methylphenyl)-(2.53%); benzaldehyde(2.42% ); phenol, 2-methoxy-(2.11%). The compound classes consist of alcohols (10), ketones(8), aldehydes(6), olefines (5), acids (4), and phenols (4).
Keywords:Gas chromatography-mass spectrometry  trogopterorum feces  volatile components  temperature- programmed retention index
