【摘要】 云南含笑鲜花的香气,用一般提取方法所得的精油或浸膏的香气与其鲜花自然散发的香气差异较大;我们利用一种新的方法——树脂吸附法,把云南含笑花从初开至凋谢整个过程所释放的香气吸附于一种憎水性树脂表面,然后通过洗脱、浓缩所得到的精油。其香气与鲜花花香气较为相似。通过GC.GC/MS/DS分析。共鉴定出29个已知化合物。更多还原

【Abstract】 The fresh flowers of Michelia yunnanensis Franch. are noted for their fresh and delicate pleasant fragrance. But to extract its essential oil and concrete by traditional method usually loses its fresh delicate character. That is the reason why it is difficult to study the constituents of its flowers fragrance and the method is not generally used by aromatic industries. We have tried to use the XAD-4 hydrophobic resin (Rohm and Haas Co.) to absorb the fragrance released from the flowers of M. yunnanensis aad have got a satisfying result. The head space was analysed by means of capillary GC/MS/DS combination and 29 different constituents were identified.更多还原
