ODAP levels in some Lathyrus species distributed on Burdur-Isparta provinces in Turkey

Abstract

Lathyrus species are distributed in natural areas of Turkey and are cultivated for use in human and animal food. Plants and seeds of Lathyrus species contain a neurotoxic substance called b-N-oxalyl-La, b-diamino propanoic acid (ODAP). When consumed in large quantities, ODAP may cause a kind of paralysis known as lathyrism. In this note, ODAP levels were determined in Lathyrus species collected in the Burdur-Isparta provinces. The leaves and seeds of plant samples were analysed using High Performance Liquid Chromatography (HPLC). ODAP was not detected in L. aphaca L. var. pseudoaphaca (Boiss.) Davis, L. sphaericus Retz., or L. aureus (Stev.) Brandza; the seed samples of L. cicera L. and L. clymenum L. contained 0.053 and 0.171% ODAP, respectively. Leaf samples of L. cicera L. contained 0.018% ODAP. This preliminary note seems to point to a secondary gene pool that may serve as a valuable source of genetic material for grass pea improvement.

Biochemical Composition of Lathyrus L. Seeds: Antioxidant Activities, Phenolic Profiles, β-ODAP and Protein Contents

“…In the present study, β-ODAP contents of the samples were between 0.20 and 1.18 mg/g. Karadeniz et al (2010) found that there was no β-ODAP in the seeds of L. aphaca, L. sphaericus and L. aureus and β-ODAP levels of L. cicera L. and L. clymenum L. seeds were 0.053 and 0.171%, respectively. Basaran et al (2016) reported the β-ODAP contents in 52 L. sativus seeds varied from 2.62 mg/g up to 5.59 mg/g.…”

“…In the study, the mean protein content of Lathyrus taxa was 26.15% (Table 5). It was reported that some cultivars of L. cicera grown in Turkey are as high in nutritional value as soybeans (Karadeniz et al, 2010). In previous study, Pastor-Cavada et al (2011) determined that protein contents of 15 Lathyrus species fall within the range of 17.7 and 25.6%.…”

“…In the Lathyrus species breeding, low β-ODAP and high protein are major interest (Basaran et al, 2016). However, β-ODAP has been determined not only in Lathyrus species, but also in other leguminous plants (Karadeniz et al, 2010). The presence of β-ODAP was shown in 13 Crotalaria species and 17 Acacia species, besides in 21 Lathyrus species.…”

Radical Scavenging Activity of Some Lathyrus Taxa Distributed in Burdur-Isparta Regio

“…We investigated RSAs of some Lathyrus taxa which we determined ODAP contents of. In our previous study, some Lathyrus species such as L. cicera which has relatively larger and lighter coloured seeds contain ODAP while L. sphaericus and L. aphaca having antioxidant activity, did not contain ODAP [10]. More studies are needed on Lathyrus' neurotoxins and secondary metabolism and genetic and environmental effects on them.…”
