Abstract
The physicochemical and theoretical relationships between the traditional equivalent carbon number (ECN) and a proposed elution theory for triglyceride molecular species that has been expressed as a matrix model were demonstrated by multiple regression analysis. It was concluded that the ECN expression has two independent variables, that is, the total acyl carbon number (CN) and the total double bonds (DB), and one dependent variable, the relative retention time (RRT). In the proposed elution equation, there are six independent variables, including the carbon numbers and number of double bonds in each acyl group to be considered.
