Abstract

Parts II, III and IV of this series deal with the component acids of Niger seed, safflower and sunflower seed oils from different parts of Africa. The linoleic acid content of such oils may range from over 70% to somewhat below 50%; the oils of high linoleic acid content possess excellent drying properties, coupled with absence of yellowing during ageing of the resulting paint film.

In this paper the component acids of the oil of Niger seed grown in Southern Rhodesia have been studied and found to contain about 73% of linoleic acid and 1%, of linolenic acid, with 7% of oleic and about 19%, a of saturated (palmitic and stearic) acids. So far as the present (somewhat meagre) records go, it appears that African Niger seed oils may usually approximate to this composition, whereas Niger seed grown in India yields oils with only about 50% (or slightly more) of linoleic acid.
