Abstract
1. The component glycerides of J. curcas, J. inultifida, J. gossypifolla and sunflower seed oils are determined by a new method of crystallisation and column chromatography on silica-silver nitrate. 2. The component glycerides of nine seed oils (safflower, tobacco, A. mexieana, maize, cotton, gi-oundnut, M. ternifolia, G. asiatica and M. latifolia) are determined by thin layer argentation procedure. 3. The results agree with those obtained by lipolysis on" calculated directly from the component acids on the basis of the theory of positional distribution. Moreover, the distribution of oleic, linoleic, hexadec-9 and 11-enoic, lauric and myristic acids in vegetable triglycerides are studied by hydrolysis with pancreatic lipase. The results, discussed in terms of a "selectivity factor", indicate that these unsaturated acids do not compete equally for the secondary hydroxyl group of glycerol.
