利用同时蒸馏萃取法(SDE)提取五灵脂中的挥发性组分。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%),十四酸(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(6种),烯类(5种),酸类(4种),酚类(4种)。

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 constituents of the volatile 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 dedecanoic acid (7.00%);alphacedrol (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).
