Lipids extracted from three pine seeds, Pinus koraiensis, Pinus armandi and Pinus cembra, were studied for general properties, fatty acid, sterol, phospholipids, and tocopherol content and autoxidation by the AOM test.All the lipids contained 14.718.6 % of Δ cis-5, cis-9, cis-12-octadecatrienoic acid (Δ 5, 9, 12-18 : 3 and designated here tentatively as pinolenic acid). The content of this acid in polar lipids was considerably less than in neutral lipids. The content of pinolenic acid in 2…

Triacylglycerol composition of Pinus koraiensis seed oil
The triacylglycerol (TG) composition of Pinus koraiensis seed oil, which contains Δ5 nonmethylene-interrupted (NMI) fatty acids (FA) (the main acid is pinolenic, 18:3 Δ5, 9, 12), was determined. TG
General characteristics of Pinus spp. Seed fatty acid compositions, and importance of Δ5-olefinic acids in the taxonomy and phylogeny of the genus
The Δ5-unsaturated polymethylene-interrupted fatty acid (Δ5-UPIFA) contents and profiles of gymnosperm seeds are useful chemometric data for the taxonomy and phylogeny of that division, and these
Δ5-Olefinic acids in the seed lipids from four Ephedra species and their distribution between the α and β positions of triacylglycerols. Characteristics common to coniferophytes and cycadophytes
It is postulated that Ephedraceae and Coniferophytes, which have evolved separately since the Devonian period (≈300 million yr ago), have kept in common the ability to synthesize C18 and C20 δ5-UPIFA.
Regiospecific analysis of conifer seed triacylglycerols by gas-liquid chromatography with particular emphasis on Δ5-olefinic acids
Results for Pinus pinaster and P. koraiensis seed oils obtained with this new simple method compared favorably with literature data established with other usual regiospecific analytical techniques, in agreement with data obtained by other methodologies allowing validation of the GLC regios pecific method.
