| 摘 要： | 自动质谱图解卷积和鉴定系统(AMDIS)是美国标准化委员会推出的一款辅助气质数据定性分析的软件,利用该软件可有效的克服GC-MS定性分析中基质效应和共洗脱效应的干扰,增加解谱的准确性和可靠性.本研究将GC-MS检测技术和AMDIS辅助解谱相结合,从雷司令葡萄果实中鉴定出15种降异戊二烯类物质,他们多数以游离态形式存在,在果实发育早期或转色前期含量最高;此外还检测到4种结合态该类化合物.在成熟果实中,β-大马士酮和β -紫罗兰酮含量远高于其感觉阈值,呈现煤油味的TDN也略高于其阈值.该研究为AMDIS技术在果实香气成分分析中的推广应用提供了参考.

| Abstract: | Automated Mass Spectral Deconvolution and Identification System(AMDIS),developed by American Standardization Committee,is a software that can assist the analysis of qualitative data from gas chromatography-mass spectrometry(GC-MS).Application of this software can effectively overcome the interference from matrix effect and co-elution effect in the process of qualitative analysis of GC-MS,thus improving accuracy and reliability of spectrum solution.In this study,fifteen norsopreniods compounds were identifie... |
