Abstract

The aim of the work was to study the chemical composition of seeds of plants Lupinus albus L., Lupinus angustifolius L., growing in the Kaliningrad region. Lupin is a promising crop due to the high content of biologically valuable protein in its seeds, as well as minerals, unsaturated fatty acids, water - and fat-soluble biologically active substances. The paper considers the amino acid, mineral, and fatty acid composition of seeds, presents data on the content of water-soluble vitamins in them, and shows the component composition of chloroform extracts of seeds. The total number of amino acids (47.72±0.37 and 38.655±0.32%, respectively) was found in the seeds of narrow-leaved and white lupine, and a high content of glutamic acid and asparagine was found. The macronutrient composition, which is dominated by potassium, phosphorus and calcium, was studied. Among the microelements of seeds, manganese, iron, zinc and silicon predominate. A particularly high content of manganese in white lupin seeds (192.14±1.67 mg per 100 g) was noted. Analysis of the fatty acid composition of lupin seed oils showed a high degree of unsaturation with a high content of oleic and linoleic acids. Both types of lupine contain thiamine, pyridoxine, and niacin, while white lupine seeds also contain Pantothenic and folic acids. Сhromatography-mass spectrometry analysis of the fraction isolated by chloroform from lupine seeds showed the presence of substances of the terpenes class (farnesene, neofitadiene, γ-tocopherol) and steriodic alcohols (campesterol, β-sitosterol).
