| 摘 要： | 马比木(Nothapodytespittosporoides)含有重要的抗癌活性成分喜树碱及其甲基衍生物.利用固相微萃取技术(SPME)提取马比木中的挥发性成分,采用气相色谱-质谱联用(GC-MS)技术对其化学成分进行分离分析,并用色谱峰面积归一化法测定各成分的相对含量.通过计算机检索,鉴定出80个挥发性化学成分,其中主要成分为2-甲基丁醛(4.851%)、2-甲基-2-丁烯醛(3.088%)、己醛(5.780%)、2-呋喃甲醛(40.413%)、(E)-2-己烯醛(6.099%)、3-己烯-1-醇(2.739%)、(Z)-己烯醇(3.260%)、正己醇(11.514%)等.

| Abstract: | Nothapodytes pittosporoides containing camptothe-cm and its methyl derivatives which are important anti-cancer active ingredients was extensively attracted as an alternative to camptotheca acuminate.Natural volatile constituents of Nothapodytes pittosporoides were extracted by using solid-phase microextraction(SPME) and separated and analysed by gas chromatography-mass spectrometry(GC-MS).The relative content of natural volatile constituents for Nothapodytes pittospo-roides was calculated to take area normalization method of chromatographic peak.Through computer retrieval,80 natural volatile constituents of Nothapodytes pittosporoides were identified.The main ingredients were 2-methyl Butanal(4.851%),2-Methyl-2-butenal(3.088%),Hexanal(5.780%),2-Furancarboxaldehyde(40.413%),(E)-2-Hexenal(6.099%),3-Hexen-1-ol(2.739%),(Z)-Hexenol(3.260%),1-Hexanol(11.514%) and so on. |
