Background. Higher fatty alcohols are a valuable raw material for pharmacology and can serve as an adaptogen in crop production, reducing post-stress effects in the cultivation of crops. Policosanols are linear saturated aliphatic alcohols with carbon atoms ranging from 20–24 to 32–34. Cereal germ contains some of the policosanols and can serve as a potential source for the isolation, purification, and further use of this class of chemical compounds. The purpose of the research is to study the features of the higher fatty alcohols content in various anatomical organs of barley seedlings under the influence of an ultra-high frequency electromagnetic field.
Materials and methods. The content of some higher fatty alcohols in barley seedlings after grain processing by ultrahigh frequency electromagnetic fields was determined by the method of chromatography-mass spectrometry.
Results. The character of distribution of 4 fatty alcohols – tetraconanol (lignocerin alcohol), docosanol (begenyl alcohol), dodecanol (lauric alcohol) and hexadecanol (cetyl alcohol) – in the anatomical organs of barley seedlings is shown. In sprouts, roots, shells and endosperm higher fatty alcohols are distributed unevenly. The predominant aliphatic alcohol is tetracosanol, found in all the studied anatomical parts of the seedling is dodecanol. Treatment of barley seeds before germination in the electromagnetic field of ultrahigh frequency allowed to increase the content of almost all studied alcohols.
Conclusions. After microwave treatment, the number of detectable aliphatic alcohols increased by 1,67 times relative to the control. The higher fatty alcohols are unevenly distributed over the organs of the barley seedling – the maximum is noted in the sprouts, the minimum – in the endosperm. Barley sprouts can be considered as a potential source of lignocerine and begenyl alcohols, where their content ishigh and is 26,20 and 5,67 %, respectively. The content of tetracosanolcan be increased more than twice by pre-microwave treatment of barley grain.
