本文采用循环吹气吸附法采集依兰鲜花头香。用毛细管气相色谱双柱保留指数和GC/MS/DS联用方法分析了依兰鲜花头香及其净油并进行了比较。从头香中完全和初步鉴定了28种组分,占总峰面积的99.51％,其中含氧化合物占92.55％;从净油中完全和初步鉴定了31种化合物,占总峰面积的84.68％,其中含氧化合物占41.76％,倍半萜类化合物占42.92％。头香的组分主要分布在保留温度90℃以下,占总峰面积的80.80％,而净油的组分主要分布在140℃以上,占总峰面积的了76.91％。头香中有13个组分在净油中没有检出。用嗅觉鉴定给出了两种样品的主要赋香成分。
In this paper, by circulating air adsorption method to collect the head of ylang flowers. The HPLC-MS / DS / GC / MS double column retention index was used to analyze the head oil and its pure oil of Yilan, and the comparison was made. A total of 28 components were identified from Amomum villosum, accounting for 99.51% of the total peak area, of which oxygen compounds accounted for 92.55%. 31 compounds were identified completely and initially, accounting for 84.68% of the total peak area, Oxygenated compounds accounted for 41.76%, sesquiterpenoids accounted for 42.92%. The components of the head fragrance mainly distributed at the retention temperature below 90 ℃, accounting for 80.80% of the total peak area, while the components of the pure oil were mainly distributed above 140 ℃, accounting for 76.91% of the total peak area. There are 13 components in the head oil that are not detected in the absolute oil. The olfactory identification gives the main aroma components of the two samples.
