“…Nevertheless, seed fatty acid profiles are generally different and in H. foetidus it is dominated by linolenic acid (C18:3) (Aitzetmüller et al 1999). This reinforces the idea that elaiosome lipid composition is not a by-product of seed biosynthesis but evolved specifically in relation with its rewarding function (Hughes et al 1994;Mayer et al 2005).…”

Geographic variations in Helleborus foetidus elaiosome lipid composition: implications for dispersal by ants

Geographic variations in the correspondence between diaspore phenotypes and disperser behavior are thought to determine the evolution of plant-animal dispersal mutualisms. Helleborus foetidus is a widely distributed plant in Western Europe, which seeds bear a lipid rich elaiosome attracting ant dispersers. Laboratory cross-tests were conducted to check the correspondence between diaspore phenotypes and ant preference in two localities of the Iberian Peninsula, Caurel and Cazorla, separated by 750 km. Diaspores from Caurel were systematically preferred to those from Cazorla by Formica lugubris (the major disperser at Caurel), and Aphaenogatser iberica and Camponotus cruentatus (both major dispersers at Cazorla). Further bioassays conducted on A. iberica only showed that differences in elaiosome traits were sufficient to explain ant preference. Separation of the lipid fractions composing the elaiosome revealed that triglycerides, diglycerides and free fatty acids were all dominated by oleic acid. The elaiosomes from Caurel contained relatively more free oleic acid but were less concentrated in linoleyl-containing triglycerides, free palmitic acid and free linoleic acid than those from Cazorla. The three lipid fractions were attractive to ants but dummies soaked with the free fatty acids extracted from Caurel were preferred to those from Cazorla. Taken together, these results reinforce the idea that oleic acid is a major releaser of seed collection by ants and suggest that geographic variations in free fatty acid composition affect the probability of diaspore removal by ants which in turn potentially determine plant demography.

“…In contrast, the Euclidean distances obtained from the HCA did not confirm significant variances in the chemical composition of C. regalis, D. elatum, and N. hispanica oils (dissimilarity < 10) suggested by PCA, which is probably caused by the presence of relatively high contents of fatty acids in all of these species. These results are in correspondence with findings of Aitzetmüller et al [24], who identified closely related patterns of fatty acids in hexane extracts obtained from seed oils of certain species of Consolida and Delphinium genera. When comparing the analytical data from this study with previously published works on the genus Nigella, it is essential to consider differences in the extraction processes used to obtain the oils, which may significantly influence their chemical composition as previously described for N. damascena [14], N. orientalis [16], and N. sativa [8] [25].…”

In this study, we analyzed the chemical composition of volatile oils hydrodistilled from seeds of Consolida regalis, Delphinium elatum, Nigella hispanica, and N. nigellastrum using GC and GC/MS. In C. regalis, octadecenoic (77.79%) and hexadecanoic acid (8.34%) were the main constituents. Similarly, the oils from D. elatum and N. hispanica seeds consisted chiefly of octadecadienoic (42.83 and 35.58%, resp.), hexadecanoic (23.87 and 28.59%, resp.), and octadecenoic acid (21.67 and 19.76%, resp.). Contrastingly, the monoterpene hydrocarbons α-pinene (34.67%) and β-pinene (36.42%) were the main components of N. nigellastrum essential oil. Our results confirm the presence of essential oils in the family Ranunculaceae and suggest chemotaxonomical relationships within the representatives of the genera Consolida, Delphinium, and Nigella. In addition, the presence of various bioactive constituents such as linoleic acid, (-)-β-pinene, squalene, or carotol in seeds of D. elatum, N. hispanica, and N. nigellastrum indicates a possible industrial use of these plants.

Abstract.-The plant family Apiaceae is known to produce a set of unusual fatty acids in the seed oils. The fatty acids and tocochromanols contents of some species of Prangos, Ferulago, Heracleum, Conium and Malabaila from Apiaceae are determined and analysed by GC, GC-MS and HPLC. Some of the studied species are endemic to Turkey. Petroselinic acid (18:1Δ6c) is the predominant constituent and consisted of more than half of the oil. Linoleic acid is the second highest fatty acid component. There is very little variation among species in the other fatty acids. In contrast, the tocopherol compositions of the seed oils differ. Tocotrienol contents of the species (except Malabaila pastinicifolia and Ferulago pauciradiata) are found to be higher than the tocopherols, particularly in view of gamma and delta tocotrienols. The relative concentrations of petroselinic acids and tocochromanols in seed oils of Apiaceae show chemotaxonomic and phylogenetic relationships. These acids have also potential as oleochemical raw materials.Key words : Apiaceae -chemotaxonomy -fatty acid -petroselinic acid -tocochromanols.Résumé.-Les Apiaceae sont connues pour leur production d'un groupe d'acides gras particuliers dans les huiles de leurs fruits. Les contenus en acides gras et tocochromanols de quelques espèces de Prangos, Ferulago, Heracleum, Conium et Malabaila, dont des endémiques de Turquie, sont étudiés et analysés GC, GC-MS et HPLC. L'acide pétrosélinique (18:1Δ6c) est le constituant dominant (plus de 50% de cette huile), suivi de l'acide linoléique ; on relève très peu de variation selon les espèces pour les autres acides. En revanche, les compositions en tocophérol de ces huiles diffèrent. Les contenus en tocotriénol (sauf chez Malabaila pastinicifolia et Ferulago pauciradiata) sont plus élevés que ceux en tocophérols, spécialement les γ et δ-tocotriénols. Les concentrations relatives en acide pétrosélinique et tocochromanols indiquent des relations chimiotaxinomic et phylogénétiques.
