THE STUDY OF CHEMICAL COMPOSITION OF FATTY OIL FROM THE SEEDS OF ARCTIUM LAPPA L.

Abstract

As a result of the study of the chemical composition of fatty oil from the seeds of Arctium lappa L. by gas-liquid chromatography it was found that it contains 9 fatty acids and trans-isomers. The main part of fatty acids is made up of linoleic (63,6%) and oleic acids (22,6%). The rest of the fatty acids are palmitic (5,4%), stearic (2,2%), palmitoleic (0,3%), eicosenoic (0,2%), linolenic (0.1%), myristic (0, 08%), heptadecanoic (0,03%) of acids and trans-isomers (0,4%). The saponification quantity of fatty oil was determined as 190.6, free fatty acids 3.5%, peroxides number 27.8, iodine number 130.8, mass fraction of phosphorus containing substances - 81 mg / kg.
