β-N-oxalyl-L-2,3-diaminopropionic acid, L-homoarginine, and asparagine contents in the seeds of different genotypes Lathyrus sativus L. as determined by UHPLC-MS/MS

ABSTRACTLathyrus sativus L. is considered one of the most promising calorie and protein sources for the vast, expanding populations living in drought-prone and marginalized areas of the world. This study was conducted to determine the β-N-oxalyl-L-2,3-diaminopropionic acid (β-ODAP), L-homoarginine, and asparagine content of a total of 173 Lathyrus sativus L. genotypes, of which 93 were collected under natural conditions in Antalya. The β-ODAP, L-homoarginine, and asparagine content of Lathyrus sativus L. genotypes ranged from 1.55 to 20.8 mg/g seeds, 1.35 to 11.64 mg/g seeds, and 0.59 to 5.22 mg/g seeds, respectively.
