摘    要:研究猕猴桃果酒中香气成分的构效关系,在分子拓扑理论的基础上,利用分子图形学技术获得了连接性指数吧,并应用AMI法得到了41种香气成分的优势构象,利用程序获得Kier指数、E—State指数和MEDV指数,基于多元回归获得了对猕猴桃果酒香气成分的保留时间(RT)作出精确估算的定量结构一保留相关关系,得到多元回归方程,相关系数达到0.947。对猕猴桃果酒香气成分保留时间的计算结果表明,计算值与实验值的一致性令人满意。

关 键 词:猕猴桃果酒  拓扑指数  保留时间  香气成分  定量结构-保留相关性

Abstract:The structure-activity relationship of flavoring compositions of kiwi fruit wine was studied.The connectivity index mL was obtained by use of molecular graphics techniques based on molecular topological theory.Then the preferential conformation of 41 kinds of flavoring compositions were obtained by AM1 method,and Kier index,E-State index and MEDV index were obtained by programs.Then based on multiple regression,the retention time of flavoring compositions of kiwi fruit wine were obtained to make accurate es...
Keywords:kiwi fruit wine  topological index  retention time  flavoring compositions  quantitative structure-retention relationship
