Exploring Phylogenetic Relationships between Hundreds of Plant Fatty Acids Synthesized by Thousands of Plants. more details ...
Abstract The triacylglycerols of meadowfoam oil have been resolved by HPLC in the silver ion and reversed-phase modes, and by the two techniques used in a complementary fashion. The fractions obtained were collected and quantified by gas chromatography of their methyl esters in the presence of an internal standard. Silver ion chromatography gave a distinctive resolution in which fractions differing solely in the position and chain-length of a single monoenoic fatty acyl group were resolved, the order of elution being 11-20:1, 5-20:1, 13-22:1, 5-18:1 and 9-18:1. Reversed-phase chromatography also gave fractions containing single positional isomers, (11-20:1<5-20:1<13-22:1<5-22:1), but the pattern was more difficult to discern since fractions containing 22:2 tended to overlap with those containing 20:1. The species (5-20:1)(5-20:1)(22:2), (5-20:1)(5-20:1)(5-20:1) and (5-20:1)(5-20:1)(13-20:1) were found to be the most abundant, and together comprised 67% of the total. A small but significant trilinolein fraction was detected and its presence may have biosynthetic implications. © 1990 AOCS Press.
