目的对胜野山楂子中挥发性成分进行分析。方法分别采用水蒸气蒸馏法、顶空进样法和超临界流体萃取法提取胜马田小檗中的挥发性成分，并结合Kovat保留指数进行气相色谱-质谱联用分析。结果水蒸气蒸馏法和顶空萃取法提取的挥发性成分以萜类成分居多，超临界流体萃取法提取的挥发性成分以烯烃、醇类和芳香族化合物居多。结论不同的样品前处理方法侧重于不同类型的挥发性成分；采用气相色谱-质谱联用Kovat保留指数对挥发性成分的鉴别更为准确、快速。
OBJECTIVE To analysis the volatile components in Alpiniae Katsumadai Semen. METHODS The volatile components were extracted from Alpiniae Katsumadai Semen by steam distillation, head space injection and supercritical fluid extraction respectively, and then analyzed by GC-MS combined with Kovat's retention index. RESULTS The volatile components extracted by steam distillation or head space extraction were found more likely to be terpenoids, whereas components extracted by supercritical fluid extraction were more likely to be alkenes, alcohols and aromatic compounds. CONCLUSION Different sample pre-treatment methods are focused on different types of volatile components; Identification of the volatile components by GC-MS combined with Kovat's retention index is more accurate and rapid.
