The paper constitutes a continuation of described investigations carried out in 1987-89 at the Research and Development Centre of „Polmos" in Konin. The quantitative content of basic carbonyl compounds: formaldehyde, acetone, acroleine as well as acetic, propionic, crotonic, isobutyric, valerianic and isovalerianic aldehydes was determined in spirits of different raw material origin by means of highly-efficient liquid chromatography. The effect of these compounds on sensoric properties of spirits was determined.
