Abstract

The aim of the work was to study the qualitative composition and determine the
quantitative content of fatty acids of roots, leaves, herb and flowers of Sakhalin (giant)
knotweed (Reynoutria sachalinensis (F. Schmidt) Nakai) by gas chromatography In Reynoutria
sachalinensis roots and flowers 12 fatty acids were identified. In the herb 13 fatty acids and in
the leaves 14 fatty acids have been identified. At least six fatty acids are classified as
unsaturated fatty acids. About 70-80% of the content in Reynoutria sachalinensis roots and
leaves dry powder were unsaturated fatty acids. Saturated and unsaturated fatty acids in herb
and flowers of the studied plant accumulated almost equally. The dominant fatty acid in
Reynoutria sachalinensis roots was linoleic acid (40.90%), in leaves – linolenic (37.20%), in
herb – arachidonic (37.05%), in flowers – palmitic (37.20%). In addition, Reynoutria
sachalinensis herb had a high content of erucic acid that equaled 8.30%. The obtained results
allow to deepen the knowledge about the fatty acid composition of the raw materials of
Reynoutria sachalinensis, to establish the relationship between pharmacodiological action and
the fatty acid composition of the raw materials, and will be used in the development of drugs
based on it.
