摘要
本文以XAD-4树脂为吸附剂,用循环吹气吸附法采集鄢陵蜡梅鲜花散发的天然香气。用双柱气相色谱程序升温保留指数(GC-RI)与双柱气相色谱与质谱(GC-MS)联用技术相结合的方法,分析鉴定了磬口蜡梅天然香气中的31种成分,共占总峰面积的97.2％。
In this study Amberlite XAD-4 resin was used as an adsorbent which adsorbed the natural flavor sent forth from Chimonanthus praceox L. flower. The eluant of the adsorbate was concentrated by using a K-D concentrator. The concentrate was then analysed by dual capillary gas chromatography-mass spectrometry and temperature programmed retention index on dual columns. A total of 31 substances were identified, which amounted to 97.2% of the total peak area. The constitution of the natural flavor and that of the petroleum ether extract were compared. Emphasis was made to employ the method of combining the dual column GC/MS with the dual column retention index to increase the reliability of the identification results.
