THE NONGLYCERIDE COMPLEX OF ONOPORDUM-ACANTHIUM SEED OIL

Abstract

An oil was obtained from crushed Scotch thistle seeds, from which in turn were extracted homologous mixtures of normal C33 - C25 paraffins, ethyl esters of C34 - C30 fatty acids and sterols with MW 414, 412 and 400. Two groups of hydrocarbons were discovered (C17 and C18), each consisting of 4 components, which differ according to the number of ethylene bonds (0 to 3). The simultaneous presence of the pentacyclic alcohols alpha-amyrin and lupeol with their natural acetates was established. C31:0 and C29:0 fatty acids were detected for the 1st time as natural compounds. Ethyl esters of fatty acids isolated from the seed oil of higher plants for the 1st time are given.
