Determinations concerning the carotenoidic compounds content was achieved on four potato varieties (Hansa, Sieglinde, Nicola and Linda) obtained from a German private sources, country were this potato varieties are frequently cultivated and consumed. The potatoes were cultivated both in the classical and biodynamic conditions. For the carotenoids extraction was used an 80% acetone water solution, and for the quantitative determination was used a colorimetric method based on the specific absorption of this compounds at different wavelength. The results interpretation was achieved with the aid of some calculus relations.
