Fatty Acid Composition of Some Ranunculaceae Seed Oils

Abstract The fatty acid composition of seed oils of eight Ranunculaceae was determinated in order to characterize new sources of gamma-linolenic acid. Fatty acids were identified as fatty acid methyl esters (FAME) by capillary gas-liquid chromatography (GC) and capillary GC-Fourier transform infrared spectroscopy (FTIR). For trienic FAME the use of a cyanopropyl-polysiloxane stationary phase (CP-Sil 88) allowed the separation with high resolution of methyl ester of columbinic acid (trans-5,cis-9,cis-12 18:3) and gamma-linolenic acid (cis-6,cis-9,cis-12 18:3). The results confirmed the presence of columbinic acid in Thalictrum seed oils, and that of gamma-linolenic acid in Anemone and related species seed oils. The taxonomic subdivision of Ranunculaceae into sub-families and tribes, which resulted from morphological considerations, did not account for the above results.

Fatty Acid Compositions

Fatty acid compositions of the seed oils of H. thermophilum Kit Tan, A. Celik & Y. Gemici, sp. nova, H. europaeum L., and H. hirsutissimum L. (Boraginaceae) were analyzed by GC/MS. The main fatty acid methyl esters were determined to be of palmitic (39.8–40.6%), linoleic (32.4–33.2%), oleic (10.6–12.1%) and stearic acids (7.9–8.5%). γ-Linolenic acid was found to be a minor component of the seed oils of the reported species. This is the first chemical report on the fatty acid composition of H. thermophilum, along with chemotaxonomic evaluation of the species.

Abstract Chloroplasts isolated from three populations of the tropical marine Chlorophyte Anadyomene stellata collected off the coast of Greece were analyzed for their fatty acid composition. Following the preparation of fatty acid methyl esters, GC-MS (El) was utilized to identify the fatty acids present in each population. Including isomers, the fatty acid profile of all three algal populations was comprised of 19 fatty acids (4 saturated, 6 monounsaturated, 9 polyunsaturated) with palmitic acid present in the highest amounts (25-27% of total fatty acids). Analysis of variance revealed significant differences amongst the three populations in the percent of total fatty acids for twelve of the fatty acids. High levels of C20 PUFAs, an atypical observation in Chlorophytes, were observed in all three populations comprising approximately 17% of total fatty acids. Furthermore a 14:2 PUFA , apparently rare in marine macrophytic Chlorophytes, was identified in significant quantities. Surprisingly, we did not find any of the conjugated tetraene containing fatty acids that we previously identified in the A. stellata populations studied from the Florida Keys.
