The quantitative structure retention relationship of the gs ms profile of yarrow essential oil

Abstract

In the essential oil of yarrow (Achillea millefolium L. sensu lato) collected from natural popula- tion on Mt. Rtanj (Serbia) and distilled by Clevenger apparatus 104 compounds were detected, and

the most abundant were camphor (9.8%), caryophyllene oxide (6.5%), terpinen-4-ol (6.3%) and 1,8-

cineole (5.6%). The quantitative structure-retention relationship (QSRR) model was employed to pre- dict the retention indices, using four molecular descriptors selected by factor analysis and a genetic

algorithm. The coefficients of determination reached the value of 0.862, demonstrating that this mo- del could be used for prediction purposes.
