利用顶空-固相微萃取法提取金橘挥发油,气相色谱-质谱联机定性定量分析成分,检测3个品种金橘的易挥发油组分.结果表明:金橘挥发油中共鉴定出28种化学成分,分别含有烯、醇、酯等化合物,以萜烯类化合物为主,D-柠檬烯占主导地位,其含量分别为50.40%、55.43%和51.47%;三个品种的金橘均含有α-蒎烯、D-柠檬烯、顺-α-杜松烯、δ-杜松烯、异石竹烯、β-榄香烯、乙酸橙花酯等十个共同组分;各品种所含特殊成分为:浏阳金弹含有4-蒈烯;桂林罗浮金柑含有右旋大根香叶烯、柏木烯、芳樟醇,阳朔圆金柑含有柠檬烯、罗勒烯、2,6,10,14-四甲基十七烷、古巴烯、2,6-二叔丁基-4-仲丁基苯酚、棕榈酸异丙酯.

The volatile compositions of three varieties of fresh kumquat were determined by using headspace solid phase micro - extraction （ HS - SPME） coupled with GC - MS. Results： Twenty - eight volatile components in the hree kumquat samples are identified. The volatile components belong to alkenes, alcohols, and esters respectively, and most of them are alkenes. D - limonene is the dominant constituent, and its contents in the three samples are 50. 40%, 55.43% and 51.47%, respectively. Ten common components are found in all of the samples, such as...
