Popis: The component acids of the seed fats of Corchorus capsularis and C. olitorius have been shown to consist of palmitic 12.0, 16.9, stearic 4.6, 3.7, arachidic 2.2, —, behenic —, 1.8, lignoceric 0.9, 1.1, cerotic 1.2, —, oleic 28.7, 9.1, linoleic 41.3, 62.5, linolenic 4.7, 0.9, and C20 mono-ethenoid 4.4, 4.0% (wt.) respectively. The seed fat of C. capsularis thus resembles cottonseed oil to some extent, whereas that of C. olitorius more nearly resembles in some respects a sunflower-seed oil. The component glycerides of the C. olitorius seed oil consist of 11% disaturated-mono-unsaturated glycerides, mainly disaturated linoleins, 64% mono-saturated-diunsaturated glycerides mainly saturated-dilinoleins, and 25% triunsaturated glycerides consisting mainly of oleodilinoleins and trilinolein. Low-temperature crystallization has shown that this oil can be resolved into typically non-drying and drying fractions respectively.
