The chemical composition of the oil extracted from the seeds of Paullinia cupana var. sorbilis (Mart.) Ducke (syn. P. sorbilis) was investigated. Cyanolipids constituted 3% of the total oil from guaraná seeds, whereas acylglycerols accounted for 28%. 1H and 13C NMR analyses indicated that type 1 cyanolipids (1‐cyano‐2‐hydroxymethylprop‐2‐ene‐1‐ol diesters) are present in the oil from P. cupana. GC and GC‐MS analysis showed that cis‐11‐octadecenoic (cis‐vaccenic acid) and cis‐11‐eicosenoic acids were the main FA (30.4 and 38.7%) esterified to the nitrile group. Paullinic acid (7.0%) was also an abundant component. Oleic acid (37.4%) was the dominant fatty acyl chain in the acylglycerols.
