“…Previous studies, some of which are old have shown that baobab seed oils contain saturated (particularly, palmitic acid) and unsaturated fatty acids (especially oleic, and linoleic acids). The proportions of palmitic, oleic and linoleic acids vary respectively between 19 and 47%, 13 and 43%, and 12 and 33% depending on the species . These oils also contain cyclopropenic fatty acids such as sterculic acid (19: CE or 9,10‐methyleneoctadec‐9‐enoic acid) and malvalic acid (18: EC or 8,9‐methyleneheptadec‐8‐enoic acid), the content of which varies from 4 to 31% .…”

Baobab seed oil contains specific fatty acids. Most of the studies on baobab fatty acids have been carried out singly and in isolation from each other, making it difficult to compare results through different species. The objective of the present study is to establish the seed fatty acid composition of each Adansonia species in order to evaluate and understand the relationships between the oil chemical compositions, the baobabs' taxonomy and, the ecological and geographical origin of each seed lot. The seed oils have been analysed using gas chromatography (GC). The oils of all baobab species contain three major fatty acids: palmitic, oleic and linoleic acids. They also contain specific fatty acids such as cyclopropenic and cyclopropanic acids, which are characteristic of the Malvaceae family seed oils. It was possible to distinguish three sections through principal components analysis using the eleven fatty acids identified by GC. The Adansonia section contains high rates of oleic acid (± 35%), the Brevitubae section is rich in palmitic acid (± 42%) and the Longitubae section contains high levels of dihydrosterulic acid (± 5%). The oil fatty acid composition, however, does not enable a definitive characterization of profiles according to species. The fatty acid composition is not significantly influenced by the geographical, soil and climate conditions of the collection sites.

“…Because of the health concerns, vegetable oils containing CPE-FAs need to be treated with high temperature or hydrogenation before consumption (16). As a result, processing costs are increased whereas transfatty acids are also produced by the hydrogenation.…”

Fatty acids containing three-member carbocyclic rings are found in bacteria and plants. Bacteria synthesize cyclopropane fatty acids (CPA-FAs) only by the addition of a methylene group from Sadenosylmethionine to the cis-double bond of monoenoic phospholipid-bound fatty acids. In plants CPA-FAs are usually minor components with cyclopropene fatty acids (CPE-FAs) more abundant. Sterculia foetida seed oil contains 65-78% CPE-FAs, principally sterculic acid. To address carbocyclic fatty acid synthesis in plants, a cDNA library was constructed from developing seeds during the period of maximum oil deposition. About 0.4% of 5,300 expressed sequence tags were derived from one gene, which shared similarities to the bacterial CPA-FA synthase. However, the predicted protein is twice as large as the bacterial homolog and represents a fusion of an FAD-containing oxidase at the N terminus and a methyltransferase at the C terminus. Functional analysis of the isolated full-length cDNA was conducted in tobacco suspension cells where its expression resulted in the accumulation of up to 6.2% dihydrosterculate of total fatty acids. In addition, the dihydrosterculate was specifically labeled by [methyl-14 C]methionine and by [ 14 C]oleic acid in the transgenic tobacco cells. In in vitro assay of S. foetida seed extracts, S-adenosylmethionine served as a methylene donor for the synthesis of dihydrosterculate from oleate. Dihydrosterculate accumulated largely in phosphatidylcholine in both systems. Together, a CPA-FA synthase was identified from S. foetida, and the pathway in higher plants that produce carbocyclic fatty acids was defined as by transfer of C 1 units, most likely from S-adenosylmethionine to oleate.

“…The presence of malvalic acid was established by GLC of the fatty acid methyl esters before and after AgNO 3 /methanol rearrangement and by direct comparison with the cyclopropenoic fatty acids of Hibiscus syriacus and Althaea officinalis (Malvaceae), including their rearrangement products. Both the GLC behavior of intact malvalic acid methyl ester and the formation (and GLC) of the various degradation and rearrangement products obtained from malvalic and other cyclopropenoic fatty acid methyl esters are well known and have been described repeatedly in the relevant literature (22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37).…”

Cyclopropenoic fatty acids in gymnosperms: The seed oil of Welwitschia

The seed oil of the gymnosperm Welwitschia mirabilis was found to contain malvalic acid, a cyclopropenoic fatty acid. This is in sharp contrast to most other gymnosperms, which contain ∆5cis-fatty acids as well as the normal set of fatty acids. The importance of this finding in relation to questions of the evolution of the Gymnospermae and Angiospermae, the two main branches of higher plants, is briefly discussed.
