采用PDMS/DVB和DVB/CAR/PDMS 两种萃取头，以固相微萃取（ SPME）法提取萝卜风味物质成分，经气相色谱-质谱联用（ GC-MS）对风味物质成分进行鉴定，分析比较两种萃取头提取的风味物质成分差别，以确定适宜的萃取头。结果表明：两种萃取头的固相微萃取共检测到29种风味成分，PDMS/DVB 提取数量为17种，DVB/CAR/PDMS为27种；PDMS/DVB萃取头所萃取的醇类、异硫氰酸酯类的数量比DVB/CAR/PDMS萃取头少2种，烷烃类少3种，杂环类少1种，酯类、酮类均未检测到；DVB/CAR/PDMS萃取异硫氰酸酯类、烷烃类、醛类、杂环类、酮类、醚类及醇类的灵敏度高， PDMS/DVB萃取芳香族类的灵敏度高。因此，根据获得风味物质数量、种类以及灵敏度，供试萃取头中，DVB/CAR/PDMS比PDMS/DVB更适于提取分析萝卜风味物质成分。

Two extraction heads, PDMS/DVB and DVB/CAR/PDMS, were used to extract the flavor compounds in radish by solid phase microextraction (SPME) method.To determine appropriate extraction head, the flavor compounds were detected by chromatography -mass spectrometry ( GC -MS) method and their differences were compared .The results showed that 29 kinds of flavor compounds in total were detected using two extraction heads .Seventeen were extracted by PDMS/DVB, and 27 were extracted by DVB/CAR/PDMS.The quantity of flavor compounds extracted by PDMS/DVB was less than that by DVB/CAR/PDMS, including 2 kinds of alcohols and isothiocyanates , 3 kinds of alkanes , 1 kind of heterocyclics .Lipids and ke-tones were not detected by PDMS/DVB.DVB/CAR/PDMS had higher sensitivity in extracting isothiocya-nates, alkanes, aldehydes, heterocyclics, ketones, ethers and alcohols, while PDMS/DVB was more sensitive in extracting aromatic compounds .According to the quantity and kind of flavor compounds and sensitivity , DVB/CAR/PDMS was more suitable for extracting flavor compounds in radish than PDMS /DVB.
