Abstract

Soybean oil fractions were obtained by collecting extract at different time intervals during
supercritical CO2 extraction. Relationships between retention behavior of seventeen TAGs and their
molecular characteristics were studied using chemometric approach. Quantitative structure-retention
relationship (QSRR) analysis was carried out on retention time values (tr) obtained by high pressure
liquid chromatography to identify structural requirements of different TAGs for their retention. Princi-pal component analysis (PCA) was performed in order to select molecular descriptors that best describe
retention behavior of the compounds investigated, and to determine the similarities among molecules.
The accurate mathematical models were developed for predicting the retention behaviour of some
TAGs. The validity of the models was evaluated by suitable statistical and cross-validation
parameters.
