Fatty Acid and Amino Acid Profiles in Some Dune Vegetation Species from Istanbul
Abstract
Dunes are one of the most dynamic ecosystems in the
nature and they are considered as a special habitat type hosting valuable
genetic resources. Dunes located in Turkey are very rich in terms of plant
diversity. Istanbul has special place for the richness of endemic and rare
species in its dune vegetations. Biochemical characteristics of some plant
species growing in Istanbul dunes, which are under immense threat during the
recent years have been examined in the present study. Seed samples and aerial
parts of the plants have been analysed for fatty acid and amino acid
compositions. The higher concentrations of α-linolenic acid were quantified in Euphorbia paralias (48.24%) and Diplotaxis tenuifolia (24.47%). Linoleic
acid concentrations were detected at the higher levels in Xanthium strumarium (68.51%) and Otanthus maritimus (66.62%). Eryngium
campestre (44.97%), Cyperus capitatus
(44.27%) and Eryngium maritimum
(41.88%) were found to have high oleic acid concentrations. 20,32% punicic acid was detected in Ecballium elaterium. The higher concentrations of some essential
amino acids were observed in the seeds. Proline is the dominant amino acid in
the aerial parts of all taxa examined. Significant correlations between amino
acid concentrations were calculated. The data obtained in the present study
reveal that regarding plants as novel crops can be efficient for utilization in
biochemical and biotechnological applications in many fields such as human
nutrition, health and other industrial purposes.
