湖北海棠叶挥发性成分的DTD-GC／MS分析

Analysis of the Volatile Organic Components in Malus hupenhensis Rehd Leaves by Direct Thermal Desorption Gas Chromatography mass Spectrometry

摘要:

摘要：采用直接热脱附—气相色谱/质谱联用技术（DTD-GC/MS）首次分析了湖北海棠叶挥发性成分，共检测鉴定出有效成分46种，主要包括烷烃类、酯类、醇类、酮类、烯类、醛类等化合物。其中，8种可用作香料添加剂，5种可作医疗用途，2种可用于杀虫剂。采用直接热脱附—气相色谱/质谱法分析湖北海棠叶挥发成分重现性好、操作简单、效率高、绿色环保。
