“…Previous investigations (19)(20)(21)(22) on the total FA composition of the seed oils from members of the Sapindaceae family showed that they are very peculiar in that cis-vaccenic and paullinic acids are major constituents and of chemotaxonomic importance. Our previous analysis of the seed oil of P. cupana (6) also confirmed those findings.…”

As a continuation of our study on plants of the Sapindaceae, the chemical composition of the oil extracted from seeds of Allophylus natalensis (Sonder) De Winter and of A. dregeanus (Sonder) De Winter has been investigated. The oil from both species contained approximately equal amounts of TAG and type I cyanolipids (CL), 1-cyano-2-hydroxymethylprop-2-en-1-ol-diesters, with minor amounts of type III CL, 1-cyano-2-hydroxymethylprop-1-en-3-ol-diesters. Structural investigation of the oil components was accomplished by chemical, chromatographic (TLC, CC, GC, and GC-MS), and spectroscopic (IR, NMR) means. GC and GC-MS analysis showed that C20 FA were dominant in the CL components of the oil from the two species (44-80% vs. 21-26% in TAG), with cis-11-eicosenoic acid (36-46%) and cis 13-eicosenoic acid (paullinic acid, 23-37%) as the major esterified fatty acyl chains in A. natalensis and A. dregeanus, respectively. cis-Vaccenic acid was particularly abundant (11-31%) in the CL from A. dregeanus, whereas eicosanoic acid (10-22%) was also a major component of CL in both species.

“…Seeds from this plant contain high amounts of caffeine and are also used to prepare a very popular carbonated soft drink in Brazil. Within the genus Paullinia, the species P. elegans (10), P. meliaefolia (5)(6)(7), P. tomentosa, and P. carpopodea (11,12) have been studied previously for the lipid content of their seed oils. Investigations on the oil composition of P. cupana have been limited and controversial (11,12).…”

Investigations on the oil composition of P. cupana have been limited and controversial (11,12). It was reported, for example, that the presence of CL and the cyanogenic features of the plant may depend on the different origins of the seeds (12).…”

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.

“…Eicosanoic acid (20:0) and eicosenoic acid (20:1 n-9) are present in high proportion in many species (Aichholz et al 1997). In the genus Paullinia, the rare fatty acids paullinic acid (Z-13-eicosenoic acid) and cis-vaccenic acid (Z-11-octadecenoic acid) are ubiquitous constituents (Seigler 1974;Spitzer 1995;Spitzer 1996;Lago et al 2000;Avato et al 2003). Other fatty acids found go from dodecanoic (12:0) to docosanoic acids (22:0) (Mikolajczak et al 1970a;1970b;1971;Aichholz et al 1997;Avato et al 2003).…”
