The volatile components of Murraya koenigii fresh leaves, collected from Surat Thani province, Thailand were studied by using headspace (HS) solid-phase microextraction (SPME) coupled with gas chromatography-mass spectrometry (GC-MS). The four fibers employed to extract the volatiles were polydimethylsiloxane (PDMS), polydimethylsiloxane-divinylbenzene (PDMS-DVB), carboxane-polydimethylsiloxane (CAR-PDMS) and polydimethylsiloxane-divinylbenzene-carboxane (PDMS-DVB-CAR). The volatile constituents of M. koenigii fresh leaves were also extracted by hydrodistillation and analyzed by GC-MS. Fifty-one compounds were identified by these fibers. Five major compounds, γ-terpinene, β-caryophyllene, β-phellandrene, a-selinene and a-pinene, were detected in all fibers. The PDMS-DVB-CAR fiber was considered as the best for trapping key volatiles of M. koenigii fresh leaves.
采用顶空（HS）固相微萃取（SPME）结合气相色谱-质谱联用（GC-MS）技术，对采集自泰国素叻他尼府的九里香叶新鲜叶片的挥发性成分进行了研究。用于萃取挥发性成分的四种纤维分别是聚二甲基硅氧烷（PDMS）、聚二甲基硅氧烷-二乙烯基苯（PDMS-DVB）、羧基-聚二甲基硅氧烷（CAR-PDMS）和聚二甲基硅氧烷-二乙烯基苯-羧基（PDMS-DVB-CAR）。还通过水蒸馏法提取了九里香叶新鲜叶片的挥发性成分，并采用GC-MS进行分析。通过这些纤维共鉴定出51种化合物。在所有纤维中均检测到了五种主要化合物，即γ-松油烯、β-石竹烯、β-水芹烯、α-芹子烯和α-蒎烯。PDMS-DVB-CAR纤维被认为是捕获九里香叶新鲜叶片关键挥发性成分的最佳纤维。
