The determination of the fatty acid composition of mowrah fat obtained from kernels of West Bengal, Bihar, Orissa and Madhya Pradesh shows that mowrah fat contains 37 to 51 % saturated acids and 49 to 63 unsaturated acids. Considerable variation is observed in the content of the four major fatty acids viz. palmitic from 15 to 32 %, stearic between 15.9 to 17.0 % and 20 to 26 %, oleic from 32.4 to 35.9 % and as high as 45 %, and linoleic from 13.9 to 17.7 %.
