We present results from flux-calibrated integrated spectra of 6 Galactic open clusters located close to the galactic center direction. Based on the measurements of equivalent widths of the Balmer lines and on comparisons with template spectra of solar metallicity, we determined the ages and E(B-V) colour excesses of the clusters. The results show good agreement with those derived from previous photometric determinations. All the clusters are found to be young objects with E(B-V) values ranging between 0.05 and 0.50 magnitudes.
