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 the sn ‐1‐and sn ‐3‐positions. Oleic acid represented 85–89% of the fatty acids at the sn ‐2‐position. Oleic acid at the sn ‐1‐ and sn ‐3‐positions showed a preference for the sn ‐1‐position. Linoleic acid was mainly esterified at the sn ‐2‐position. The amounts of saturated fatty acids, i.e., palmitic and stearic acids, and of oleic acid, at the sn ‐1‐ and sn‐3‐positions, were linearly related to their respective contents in the total triglycerides.
