Determination of unsaturated fatty acids in Shorea robusta seed oil by spectrophotometric method

Abstract

Unsaturated fatty acids of sal oil were estd. by the spectrophotometric method of Hilditch, et al (1945). The oil contained ∼30% oleic acid and 2.2% linoleic acid and no linolenic acid. One variety each of butter fat and peanut oil were analyzed in comparison with Shorea robusta (sal) seed, both crude and refined.
