Analysis Natural Volatile Constituents of Nothapodytes Pittosporoides with SPME -GC-MS

摘要

摘要: 马比木( N o t h a p o d y t e sp i t t o s p o r o i d e s )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( S PME )提取马比木中的挥发性成分,采用气相色谱-质谱联用(G C - M S )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8 0个挥发性化学成分,其中主要成分为2 -甲基丁醛( 4.8 5 1% )、2 -甲基- 2 -丁烯醛( 3. 0 8 8% )、己醛( 5. 7 8 0% )、2 -呋喃甲醛( 4 0. 4 1 3% )、( E ) -2 -己烯醛( 6. 0 9 9% )、3 -己烯- 1 -醇( 2. 7 3 9% )、( Z ) -己烯醇( 3. 2 6 0% )、正己醇( 1 1. 5 1 4% )等.

Abstract: Nothapodytes pittosporoides containing camptothe-cin 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.
