“…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.

“…sorbilis. Two previous papers (6,12) reported the total content of FA in guaraná seed oil; however, only a general description of the occurrence of homologs was given, without further characterization of their unsaturation position. Moreover, in both cases, only methyl ester derivatives were analyzed.…”

“…Previous detailed investigations on the total FA composition of seed oils from other members of the Sapindaceae (6,12) showed that they were very peculiar in that cisvaccenic and paullinic acids were the principal components; these have been proposed as chemotaxonomic markers for the plant family. In fact, cis-vaccenic acid normally occurs in seed oils in low amounts, and paullinic acid appears to be very rare in the plant kingdom; it has been reported in some Proteaceae (25) and, within the Sapindaceae, in the oil of Sapindus trifoliatus (26).…”

“…1; I-IV), with FA esterified to a mono-or a dihydroxynitrile moiety, have been reported as occurring in this plant family (4,5); types I and IV CL are cyanogenic. Moreover, compositional studies on the overall lipids isolated up to now from Sapindaceae plants have indicated that they are characterized by a particularly high content of eicosanoic (20:0) and eicosenoic (20:1) FA (6,7).…”

“…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).…”

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.
