COMPONENT GLYCERIDES OF VEGETABLE FATTY OILS, PART I. NIGER SEED OIL.

The fatty oil extracted from the seed of Guizotia abyssinica (Niger seed) has been found to contain myristic acid (along with some capric, caprylic and lauric acids) (1.7%), palmitic acid (5%), stearic acid (2%), oleic acid (38.9%) and linolic add (51.6%) along with traces of archidic, behenic and lignoceric acids.

The glyceride structure of the oil has been determined by brominating the neutral oil, resolving the brominated solid and liquid products into a number of simpler fractions and estimation of the fatty acid composition of the different fractions. The component glycerides of the oil have been found to be trilinolin (2%), oleo-di-linolin, (40%). di-oIeo­linolin (30%⁾, myristo-di-linolin (2%) myristo-oleo-linolin (3%), palmito-di-linolin (6%), palmito-oleo-linolin (II %), stearo-di-linolin (2%) and stearo-oleo-linolin (4%).
