摘　　要：[目的]分析四棱豆(Psophocarpus tetragonolobus D.C)种子中的挥发性成分,以期为更好地利用此资源提供基础。[方法]采用GC-MC方法测定了4个四棱豆品种的挥发性成分,通过面积归一法计算出各成分的相对含量。[结果]4个四棱豆品种共检测出烷烃类、烯烃类、酸类、芳香族化合物、酯类、酮类、醚类、杂环类等10大类共125个化合物;每个品种挥发性成分42个左右,主要挥发性成分为酮类、醇类、酯类等物质,不同品种之间挥发性成分种类、总量差异不明显;但各组分相对含量差异性很大。[结论]挥发性组分之间的差异性形成各自的风味特点,其存在与差异性构成加工过程中四棱豆产品之间的差异。[Objective] To analyze volatile substances from Psophocarpus tetragonolobus D.C seeds,so as to provide a basis to make better use of this resources.[Method] Volatile substances extracted from Psophocarpus tetragonolobus D.C seeds were identified by GC-MS,and their relative contents were determined through area normalization method.[Result] 125 kinds of compounds in 10 types including alkanes,qlefine,acids,aromatic compounds,esters,ketone,ethers and heterlcyclic series were identified from 4 Psophocarpus tetragonolobus D.C seeds.Moreover each kind of seeds had 42 volatile substances mainly referred to ketone,alcohol and esters.There was no significant difference regarding types and total amount of volatile substances from Psophocarpus tetragonolobus D.C seeds among different species,but their relative contents were differed obviously.[Conclusion] The existence and differences of volatile substances formed their own characteristic flavors that could contribute to products variation in the processing of Psophocarpus tetragonolobus D.C.
