Abstract
Triglycerides of mango seed kernel fat contain, depending on the variety, 32.4–44.0% of stearic acid and 43.7–54.5% of oleic acid. Palmitic and linoleic acids represent, respectively, 5.9–9.1% and 3.6–6.7% of the fatty acids. The triglycerides also contain minor amounts of arachidic and linolenic acids. Palmitic, stearic and arachidic acids were almost exclusively distributed among thesn‐1‐andsn‐3‐positions. Oleic acid represented 85–89% of the fatty acids at thesn‐2‐position. Oleic acid at thesn‐1‐ andsn‐3‐positions showed a preference for thesn‐1‐position. Linoleic acid was mainly esterified at thesn‐2‐position. The amounts of saturated fatty acids, i.e., palmitic and stearic acids, and of oleic acid, at thesn‐1‐ and sn‐3‐positions, were linearly related to their respective contents in the total triglycerides.
