Fatty acids and tocochromanol patterns of some Turkish Apiaceae (Umbelliferae) plants; a chemotaxonomic approach

Abstract

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.

Tannin, protein contents and fatty acid compositions of the seeds of several Vicia L. species from Turkey

“…Vicia peregrina had the lowest level of saturated acid and V. angustifolia had the highest amount of saturated fatty acid (SFA) concentration (Table 1). on the other hand, the unsaturated fatty acid composition of the Vicia species was determined at levels as high as those reported for other family members of the Vicia species (Pastor-Cavada et al, 2009a), Fabaceae (Bagci et al, 2004a), Lamiaceae (Bagci, 2007), Boraginaceae (Bagci et al, 2004b), Apiaceae (Bena et al, 1998) (Bakoglu et al, 2009).…”

Fatty Acid Patterns of Seeds of Some Salvia Species from Iran – A Chemotaxonomic Approach

“…Gas chromatography (GC) fingerprinting of the FAs composition is a valuable tool in chemotaxonomic studies . Several studies clearly have confirmed the chemotaxonomic relationships between angiosperm families, such as Boraginaceae , Cannabaceae , Lamiaceae , Apiaceae , Rubiaceae , Malvaceae , and Vitaceae by evaluating the patterns of the FAs composition. There are a few studies that have been focused on the chemotaxonomic importance of the FAs composition in Salvia seed oils .…”

Biological flora of New Zealand 12:Griselinia lucida, puka, akapuka, akakōpuka, shining broadleaf

“…This is supported by many observations of insect herbivory on G. lucida and very few of mammalian browsing (see Other biotic and abiotic roles, below). G. lucida also produces the fatty acid petroselinic acid but lacks proanthocyanidins and ellagic acid, features which have been useful in taxonomic classification (Bagci 2007).…”
