Analysis of the monosaccharide composition showed that the composition of the neutral polysaccharide BSP-1-1 is represented by monosaccharides in the following composition: ribose – 5.05%, arabinose – 56.38%, mannose – 5.87%, glucose – 8.63% and galactose – 24.05%. The composition of the anionic polysaccharide BSP-2-1 is represented by monosaccharides: ribose – 6.35%, arabinose – 60.15%, mannose – 7.19%, glucose – 4.12% and galactose – 22.16%. It was determined that the isolated polysaccharides consist mainly of arabinose (BSP-1-1 – 56.3%, BSP-2-1 – 60%) and galactose (BSP-1-1 – 24%, BSP-2-1 – 22%). Based on the data obtained, it can be assumed that the studied polysaccharides from the seeds of the turnip Brassica rapa belong to the type of arabinogalactans. According to the results of studying the properties of acute toxicity of the BSP polysaccharide from the seeds of the turnip Brassica rapa, it was found that this substance belongs to class V compounds - practically non-toxic substances. With intragastric administration of inulin at doses of 25, 50, and 75 mg/kg and BSP polysaccharide from the seeds of the turnip Brassica rapa at doses of 10, 20 and 30 mg/kg 14 days after the induction of diabetes mellitus, the indicator was close to that of the intact group of animals (intact - 3.07 ± 0.25, inulin 2.99 - 3.14 ± 0.23, and BSP polysaccharide from the seeds of the turnip Brassica rapa 2.53-3.14 ± 0.20), while the indicator of the control group was - 8.40 ± 0.35.

This study will provide an opportunity to plan and conduct studies to study the action of substances in the metabolism of glucose and lipids, which examines the enzymes that regulate the lipid activity of the liver, as well as the morphology of the liver and adipose tissue.
