FATTY ACID PATTERNS OF THE SEED OILS OF SOME LATHYRUS SPECIES L. (PAPILIONIDEAE) FROM TURKEY, A CHEMOTAXONOMIC APPROACH EYÜP BAĞCI* AND AHMET ŞAHIN
Abstract: Seed
oils of 16 Lathyrus (Fabaceae) species belonging to different sections
viz., Cicercula, Orobastrum, Orobon, Platystylis, Lathyrus and Pratensis
were investigated for their fatty acid composition with gas liquid chromatography.
Unsaturated fatty acids, particularly linoleic and oleic acid comprised more than
50 % of seed oil. The fatty acid composition of the studied Lathyrus taxa
were found as identical qualitatively, but some quantitative differences were
observed in infrasectional and interspecific level. Linoleic acid was found major
component as unsaturated fatty acid (average 48 %). Oleic and linolenic acid were
the second highest major unsaturated fatty acid components. On average, palmitic
acid was the major saturated acid present (average 14 %). Lathyrus species
showed linoleic - palmitic acid type FA patterns. Similar conclusions were detected
in the sectional classifications of Lathyrus sp., as reported earlier.
The results obtained from this study were discussed with the genera and family
patterns. Some differences were determined in the main type fatty acid in family
patterns in particular subfamily Mimosoideae and Caeselpinioideae. Chemotaxonomic
and renewable resources implications of the components of fatty acids and plant
taxa are discussed.
