Analysis was made of the precipitate formed during the settling of crude sesame seed oil. It was found mainly to consist of dicarboxylic acid (DA, 78%), sterylglycoside (SG, 7%), and non-lipid (7%). About 92% of DA was octacosanedioic acid and four other DA with different carbon numbers. DA and SG content in crude oil was about 0.5% and 700 ppm, respectively.
DA and SG were removed for the most sort from the crude oil as the precipitate.
