中文摘要: 采用固相微萃取技术萃取食用菊花(Dendranthema morifolium)品种的挥发性成分,利用气相色谱-质谱联用技术(solid-phase microextractions-gas chromatgraphy mass spectrometrometry,SPME-GC/MS)进行分析,并用峰面积归一化法得出各组分的相对百分含量。结果显示:共鉴定出51种挥发性成分,包括烯类、酯类、醇类,还有少量酸、杂环类和烷类物质,其中主要成分为单萜类化合物α-蒎烯、β-月桂烯、α-松油烯、β-蒎烯、γ-松油烯等,相对含量分别为74.04%、5.24%、3.96%、3.44%、2.01%,共占总相对含量的88.69%。表明固相微萃取气相色谱-质谱联用技术方法能准确反映食用菊花中的挥发性组分,可为食用菊花资源的开发利用提供科学依据。
Abstract:Volatile chemical constituents in flowers of chrysanthemum were analyzed by means of top solid phase microextraction gas chromatography/mass spectrometry(SPME-GC/MS).The results showed that 51 volatile aroma components,including alkenes,esters,alcohols and a small amount of acids,heterocycles and alkanes.The main component was monoterpenoids α-pinene,β-myrcene,α-terpinene,β-pinene,γterpinene and their relative contents were 74.04%,5.24%,3.96%,3.44%and 2.01%respectively,accounting for 88.69%of the total relative content.Monoterpenoids were the main components of various types of essential oils.The study provided a theoretical basis for the deep processing of this variety.
