Abstract

The volatile components in single-flowered and double-flowered Chinese narcissus were identified by headspace-solid phase microextraction (HS-SPME) coupled with GC and GC/MS. Changes in aroma during the vase-life (days 0, 1, 2, 3, 4, 5 and 6) of two samples were also studied. A total of 35 compounds were identified, of which all were present in single-flowered and 26 in double-flowered samples. The main aroma components were (E)-β-ocimene, and benzyl acetate. Single-flowered narcissus have a higher percentage of benzyl acetate, while double-flowered narcissus have a higher percentage of 1,8-cineole. In vase-life, the total volatile component content peaked on day 2 for single-flowered and day 3 for the double-flowered narcissus. For both single-flowered and double-flowered narcissus flowers, the total content of volatile components had decreased significantly by day 4.

摘要

采用顶空固相微萃取(HS-SPME)结合 GC 和 GC/MS 对单瓣和重瓣中国水仙的挥发性成分进行了鉴定。还研究了两个样品在瓶插期间(第 0、1、2、3、4、5 和 6 天)香气的变化。共鉴定出 35 种化合物,其中单瓣水仙中均有存在,而重瓣水仙中有 26 种存在。主要香气成分是(E)-β-罗勒烯和乙酸苄酯。单瓣水仙中乙酸苄酯的比例较高,而重瓣水仙中 1,8-桉叶素的比例较高。在瓶插期间,单瓣水仙的总挥发性成分含量在第 2 天达到峰值,而重瓣水仙的总挥发性成分含量在第 3 天达到峰值。对于单瓣和重瓣水仙花朵,第 4 天挥发性成分的总含量显著下降。
