Abstract
AbstractSeeds from Raja flax and Indian safflower were collected at increasing stages of maturity and the free lipid extracted from them with hexane. The true lipid material obtained in this manner was separated into lipid classes by silicic acid column chromatography using a diethyl ether‐hexane gradient and methanol for the phospholipids. Thin‐layer chromatography was used to establish the homogeneity of each lipid class. The composition of the lipid classes was examined by a combination of gas‐liquid, silicic acid‐impregnated paper and thin‐layer chromatography.With both flax and safflower, the relative amounts of the different lipid classes were shown to vary as the seed matured; the phospholipids showed the greatest degree of change. Free fatty acid, mono‐ and diglycerides were not encountered; acidity, when present, was not due to lipid material. Differences within lipid classes were also investigated.
