摘要:

基于化学拓扑理论,计算53 种红莓发酵酒香气成分化合物的两类拓扑指数值:Kier 价连接性指数(mXtv)和Hall 电性拓扑态指数(En)。通过最佳子集回归,建立红莓发酵酒香气成分定量结构- 色谱保留时间相关(QSRR)模型,最佳六元回归模型为:tR= - 1.943 + 5.643X4 - 4.571X5 + 0.518E6 + 0.819E7 + 0.280E13 + 0.383E16,相关系数为0.959。通过Jackknife 法和交互检验证明该模型具有总体稳健性和良好的预测能力。结果表明:电拓扑指数和分子价连接性指数能够较全面地表征分子结构特征,能有效揭示影响化合物色谱保留时间的本质因素。

Abstract:

Based on the chemical topological theory, Kier’s molecular valence connectivity index (mXtv) and Hall’s electrotopological state index (En) of 53 aromatic components in red raspberry wine were calculated. A model corresponding to quantitative structure-retention relationship (QSRR) of retention time (tR) of 53 aromatic compounds with mXtv and En were deduced by Leaps-and-Bounds regression. A satisfactory relationship was expressed to be tR = -1.943 + 5.643X4- 4.571X5 + 0.518E6 + 0.819E7 + 0.280E13 + 0.383E16 with a coefficient (R) of 0.959. This model exhibited excellent stability and predictability evaluated by Jackknife method and cross-validation procedure. The regression results indicated that the electro-topological state index and molecular connectivity index could characterize molecular structures and demonstrate the essential affecting factors of tR of aromatic components in red raspberry wine.

Key words: red raspberry wine, aromatic component, molecular valence connectivity index, electro-topological state index, QSRR
