A review on petroselinic acid and its derivatives

Abstract

This publication contains a comprehensive review of literature on petroselinic acid and its derivatives. All known sources of petroselinic acid including its synthetic derivation have been explored and described. The different plant species, whose seeds offer an oil reported to contain petroselinic acid, have been listed and the amounts of oil and their prevalent fatty acid components given. Its method of isolation from the naturally occurring triglycerides and identification have been discussed. The descriptions of characteristics and properties of petroselinic acid and its various derivatives are also included. In many cases they have been compared to oleic acid and other related fatty acids and their derivatives. The various methods of chemical modification of petroselinic acid have been, investigated and the derivatives obtained have been summarized in tabular form. Some potential uses for petroselinic acid and the products obtained from it have also been discussed. This review was designed to show that is known about petroselinic acid to date, and perhaps to create further interest in research on this unique naturally occurring octadecenoic acid.

Geranium sanguineum (Geraniaceae) seed oil: A new source of petroselinic and vernolic acid

“…Petroselinic acid is the characteristic FA for seed oils of the plant order Umbelliflorae, where it occurs in high amounts. Levels of up to 85% have been reported in only three plant families (Umbelliferae, Araliaceae, and Garryaceae) (1,2). This acid has not been previously reported as a main component of seed oils from other than these three plant families, and this work extends the list of natural sources of petroselinic acid by the plant family Geraniaceae.…”

“…This extends the list of natural sources of these two unusual FA (2,8) by inclusion of the Geraniaceae plant family. As a part of our screening program of lesser-known seed oils, the seed oil of G. sanguineum was analyzed for its FA composition.…”

Method for obtaining three products with different properties from fennel (Foeniculum vulgare) seed

“…Another study demonstrated that biodiesel fuels high in monounsaturated FAs yields superior fuel properties relative to those enriched in saturated or polyunsaturated FAs (Moser and Vaughn, 2012). Monounsaturated FAs may comprise 86% of FA profile of FSO (Placek, 1963).…”

“…The principal fatty acid (FA) in fennel seed oil (FSO) comprising 60-85% of the content is petroselenic acid (PA; C18:1 6c; 6Z-octadecenoic acid) (Charvet et al, 1991;Placek, 1963). PA is of particular interest because its oxidation yields lauric and adipic acids (Corma et al, 2007;Placek, 1963).…”

Dehulling of coriander fruit before oil extraction

“…Petroselinic acid (C18:1 6) is the main fatty acid (up to 80%) in the fatty oil (Kleiman and Spencer, 1982). Coriander oil is of interest because of its potential application in oleochemistry (Placek, 1963). Petroselinic acid, an isomer of oleic acid, opens up another approach to the manufacture of medium chain fatty acids (MCFAs), since it can be split into lauric (C12:0) and adipic (C6) acids by oxidative cleavage.…”
