HS-SPME & GC-MS分析印加果种子的挥发性物质

利用顶空固相微萃取-气相色谱质谱法(HS-SPME & GC-MS)分析印加果Plukenetia volubilis近成熟种子的挥发性物质，通过面积归一法计算出各成分的相对含量。结果共分离鉴定出64种化学成分，其中6种酯类化合物，占45.86%；12种醇类化合物，占27.71%；7种烯烃类化合物，占6.71%；9种醛类化合物，占3.89%；6种酮类化合物，占2.78%；16种烷烃类化合物，占1.78%。此外，盐酸氨基脲占5.47%，氨基脲占3.25%，还有1.51%三氯乙酸和0.23%甲基异丙基苯及其他化合物。

Analysis of Volatile Components from Plukenetia volubilis Seed by HS-SPME & GC-MS

In order to reveal the aroma characteristics of Sacha Inchi seed oil, volatile components from nearly-matured seed of Sacha Inchi were analyzed by HS-SPME & GC-MS and the relative content of each component was determinated by area normalization. The results showed that 64 chemical composition were detected and identified including 6 ester compounds (45.86%), 12 alcohol compounds (27.71%), 7 alkene compounds (6.71%), 9 aldehyde compounds (3.89%), 6 ketone compounds (2.78%) and 16 alkane compounds (1.78%). Moreover, semicarbazide hydrochloride (5.47%), hydrazine carboxamide (3.25%), trichloro-acetic acid (1.51%), methyl(1-methylethyl)-benzene (0.23%) and others were also identified.
