STUDIES IN INDIAN SEED OILS .7. 4 OILS WITH UNUSUAL CONSTITUENTS

Abstract

The percentages by weight of palmitic, hexadecenoic, stearic, oleic, linoleic, linolenic and arachidic acids were determined in the seed fats fo Bunium cylindricum (Umbelliferae), Euonymus hamiltonianus (Celastraceae), Crotalaria intermedia (Leguminosae)and Solanum khasianum (Solanaceae) by gas-liquid chromatography. An unusual component in the first fat was 38·5% petroselinic acid and in the second 8·5% (by wt.) acetic acid. The other two fats contained higher chain length components: a total of 4·0% of 22:0,24:0 and 26:0 acids and 0·1, 0·3 and 0·1% of 21: 0, 23:0 and 25:0 linear acids in C. Intermedia and 1·5% of a possible 19:0 branched-chain acid and 0·1% of an apparent 22:1 acid in S. khasianum.
