The seed oils of some species of the family Cruciferae
SummaryThe physicochemical properties of the oils of the seeds of seven plants of the family Cruciferae —Cakile maritima, Sisymbrium altissimum, Sisymbrium Loeselii, Descurainia Sophia, Erysimum cheiranthoides, Brassica amoracioides andCrambe pontica — have been studied and their fatty acid compositions have been determined. The results obtained showed no marked differences from those given in the literature.
Search for new industrial oils. XIII. Oils from 102 species of cruciferae
Seed from additional species of Cruciferae have been analyzed for crude protein, oil and fatty acids in the oil. Oils were like those reported earlier from other crucifers, except forCardamine impatiens which is unique among known seed oils because it contains some 25% dihydroxy acids. Erucic acid is present (0.3–55%) in about three-fourths of the 102 samples. Eicosenoic acid is a major constituent (32–53%) in four species and monohydroxy acids (45–72%) in another four. Linolenic acid occurs (2–66%) in oil of all species.
Acetylation analysis of saccharides. 2. Microanalysis of neutral glycosphingolipids by means of acetylation with radioactive acetic anhydride.
Abstract The quantitative analysis of mixtures of glycosphingolipids by acetylation with radioactive acetic anhydride and separation by thin-layer chromatography is described. The method was primarily developed for screening of glycosphingolipid composition of tissues, cultured cells, and virus preparations. The sensitivity and linearity of the method is demonstrated. Although theoretically a much higher sensitivity is achievable, in practive about 10 −9 g of glycosphingolipid can be detected and tentatively identified. As an example, the acetylation pattern of lipids from a preparation of herpes simplex virus is demonstrated.
