We present some preliminary results obtained within the MAGPOP-ITP collaboration for a subsample of four dwarf elliptical galaxies. On the basis of high-resolution, optical spectroscopic data obtained for these galaxies at the WHT, their ages, metallicities and single element abundance ratios have been derived from their line-strength indices and the improved, MILES-based, stellar population model predictions by Vazdekis et al. (in preparation).
