Abstract

The research on the amino acids (valine, arginine, tryptophan, methionine, lysine, histidine, phenylalanine, isoleucine) and water-soluble vitamins (B1, B2, B6, C) content in species of the family Hydrocharitaceae, growing in Western Siberia (Elodea canadensis, Stratiotes aloides Hydrocharis morsus-ranae, Hydrilla verticillata), has been executed.Fiveindispensable (valine, isoleucine, lysine, tryptophan, phenylalanine) and two dispensable(arginine, histidine) amino acids have been discovered at examined species of family. It has been found that all examined Hydrocharitaceae have a comparatively high content of valine (H. morsus-ranae has a maximum valine content ((420 ± 30) × 10-7 g / 100 g)). The high content of vitamin C (S. aloides ((770 ± 30) × 10-7) and H. morsus-ranae ((750 ± 30) × 10-7 g / 100 g) have a maximum content) and the equally low content in all examined species of vitamin B6 (at a rate of ((19 ± 2) × 10-7 g / 100 g) are typical.

Highlights

  • Five indispensable and two dispensable amino acids have been discovered at examined species of family

  • It has been found that all examined Hydrocharitaceae have a comparatively high content of valine (H. morsus-ranae has a maximum valine content ((420 ± 30) × 10-7 g / 100 g))

  • The high content of vitamin C (S. aloides ((770 ± 30) × 10-7) and H. morsus-ranae ((750 ± 30) × 10-7 g / 100 g) have a maximum content) and the low content in all examined species of vitamin B6 (at a rate of ((19 ± 2) × 10-7 g / 100 g) are typical
