Fatty acids of some Indian seed oils: seed fats of Mesua ferrea, Calophyllum inophyllum and Pistacia vera

Abstract

The fatty acids of Mesua ferrea (Malabar) had the following % compn.: myristic 1.8, palmitic 6.3, stearic 10.7, oleic 49.2, linoleic 7.3, unsaponifiable 24.7. These figures correspond with a sapon. no. of 290.9 and an I no. of 73.2 for the actual glycerides present in the oil. The fatty acids of Mesua ferrea (Bengal) in % compn. were: myristic 1.4, palmitic 7.5, stearic 9.2, arachidic 1.7, oleic 58.7, linoleic 9.9, unsaponifiable 11.6. The % compn. of the fatty acids of the neutral glycerides of Calophyllum seed fat was: palmitic 15.8, stearic 10.2, oleic 49.4, linoleic 24.0, unsaponifiable 0.6. The I no. of the original oil was 92.1 and the sapon. no. 286.6. The % compn. of the fatty acids of Pistacia vera as found was: myristic 0.6, palmitic 8.2, stearic 1.6, oleic 69.0, linoleic 19.8, unsaponifiable 0.8. These figures correspond with a sapon. no. of 291.6 and an I no. of 94.7 for the actual glycerides present.
