Chemical Composition of Seeds of Two Endemic Lathyrus L. Species from Turkey

Abstract

Genus Lathyrus L. belonging to Fabaceae (Leguminosae) family consisted of 77 taxa at the species, subspecies, and variety level at Turkey and 25 of that were known as endemic. Lathyrus egirdiricus H.Genc & A.Sahin and Lathyrus tefennicus H. Genç & A. Şahin were endemic species and described at the date of 2008 and 2011, respectively. The seeds of Lathyrus tefennicus and Lathyrus egirdiricus were collected in Tefenni of Burdur province and Eğirdir of Isparta province in May of 2016 at Turkey. The concentration of Cd, Cr, Ni, Cu, Mn, Zn, Fe, Ca, Mg, Na and K in the Lathyrus tefennicus and Lathyrus egirdiricus seeds were determined by Atomic Absorption Spectrometry. A microwave oven was used for the sample digestion. The accuracy of proposed method was confirmed by the analysis of the certified reference material (EnviroMAT Contaminated Soil). All results were given at 95% of confidence level. The presence of different concentrations of elements in the seeds of both species strengthens the belief that this data can be used in plant taxonomy.
