In order to determine the aroma components of tassel of carrot,the essential oils were extracted by headspace solid phase microextraction (HS-SPME) then separated and identified by gas chromatography-mass spectrometry (GC-MS).The relative content of each compound was calculated by area normalization method.48 compounds were detected from essential oils of tassel of carrot,and 42 of them were identified,which account for 97.83％ of total flow area,including 29 terpenes,4 oxygen containing compounds,3 alcohols,2 aromatic compounds,1 ester,1 ketone,1 acid and 1 ether.The main content of the essential oils are alpha pinene (22.66％),beta pinene (28.98％),caryophyllene(15.63％),D-limonene(8.00％)and ocimene(6.95％)respectively.%采用顶空-固相微萃取技术对胡萝卜缨中挥发性成分进行富集,应用气相色谱-质谱联用法对其中的化学成分进行分离和鉴定,采用面积归一法测定其相对含量.共检出挥发性成分48种,鉴定出其中的42个组分,占挥发油总量的97.83％;主要成分为烯烃类29种、杂环类4种、醇类3种、芳香族类2种、酯类1种、酮类1种、有机酸类1种、醚类1种;含量较高的分别是α-蒎烯(22.66％)、β-蒎烯(28.98％)、石竹烯(15.63％)、柠檬烯(8.00％)、罗勒烯(6.95％).
