摘要/Abstract

摘要： 提出顶点及顶点相互作用矢量的概念，并将该矢量用于复杂样本的分子结构表征。采用逐步回归结合统计检测对变量进行筛选后，再用多元线性回归建立了定量结构-色谱保留(QSRR)关系的7变量模型，模型的建模计算值复相关系数(R)为0.990，标准偏差(SD)为1.325；留一法(LOO)交互检验复相关系数(RCV)为 0.983，标准偏差(SDCV)为1.696。结果表明该矢量具有较强的分子结构表达能力，模型具有良好的估计能力与稳定性。

Abstract: The concept of vectors of vertexes and their interaction were proposed to characterize the molecular structure of complicated samples.Through stepwise multiple regression (SMR),a model with 7 variables could be obtained by multiple linear regression (MLR).The correlation coefficient (R) of the model was 0.990 and the standard deviation (SD) was 1.325.Then the model was evaluated by the cross validation with the leave-one-out (LOO) procedure and the correlation coefficient (RCV) of 0.983 and standard deviations (SDCV) of 1.696 were obtained.The results showed that the vectors were superior in molecular structural characterization.The stability and predictability of the model was satisfactory.

Key words: Meconopsis integrifolia Franch, volatile organic compounds (VOC), structural descriptor, quantitative structure-retention relationship (QSRR)
