Abstract

In the present study, fatty acid composition in mature seeds of the Lathyrus L. taxa were determined by using gas chromatography. Present results indicate that the seed oils of studied Lathyrus taxa have palmitic acid (C16:0) and stearic acid (C18:0) as major saturated fatty acids. Moreover, the present data show that oleic acid (C18:1), linoleic acid (C18:2 n 6) and α-linolenic acid (C18:3 n 3) are major unsaturated fatty acids in studied Lathyrus taxa. The highest oleic acid (C18:1 n 9) content is found in L. vinealis (26.8 %) but it is found at the lowest level in L. aphaca var. modestus (8.3 %). In addition, present study determines that investigated Lathyrus species have linoleic acid (42.8–62.8 %) and linolenic acid (9.2–12.9 %) contents.

Résumé

Dans la présente étude, la composition en acides gras des graines mûres de plusieurs Lathyrus a été déterminée par chromatographie en phase gazeuse. Les résultats présentés indiquent que les huiles de ces graines contiennent pricipalement l'acide palmitique (C16: 0) et l'acide stéarique (C18: 0) comme acides gras saturés. En outre, les données montrent que l'acide oléique (C18: 1), l'acide linoléique (C18: 2 n 6) et l'acide linolénique (C18: 3 n 3) sont les principaux acides gras insaturés. La plus grande quantité d'acide oléique (C18: 1 n 9) a été trouvé chez L. vinealis (26.8 %) mais il a été constaté au niveau le plus bas dans L. aphaca var. modestus (8.3 %). En outre, cette étude a déterminé que les taxons étudiés ont aussi de l'acide linoléique (42.8–62.8 %) et de l'acide linolénique (9.2–12.9 %).
