title: Seed oil composition of Paullinia cupana var. sorbilis (Mart.) Ducke.
abstract: 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 I 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.
