英文摘要	Lotus creticus L. (Fabaceae) is largely grown in the Mediterranean zone and considered as a socioeconomic and ecologically valuable species in the rural and arid Tunisian regions. In the present work, we focused on the unexploited seeds of four ecotypes of this plant regarding their storage proteins, phytochemicals, and antioxidant potential. Both colorimetric assays and electrophoretic analysis revealed that L. creticus seeds are promising sources of protein and their total contents were in the range of 197.55-248.27 mg/g DW. Albumins constituted the major fraction and formed about 45.08% of total proteins, followed by globulins (27.32%), and glutelins (19.38%). The prolamin fraction presented only 8.22%. The methanolic extracts of the seeds were rich in phenolics. The total polyphenol and flavonoid contents were found to be in the range from 7.05 to 8.11 mg GAE/ g DW and 11.83 to 14 mg QE/g DW, respectively, whereas the condensed tannin amounts ranged between 1.78 to 2.19 mg CTE/g DW. Moreover, the studied seeds extracts possessed high antioxidant potential as evidenced by their total antioxidant capacity (6.74-8.11 GAE/g DW), free radical DPPH scavenger activity (IC50 = 15.67-22.17 mg/mL), and reducing power (EC50 = 6.90-9.07 mg/mL) which were mainly due to the presence of several phenolics in the extracts. A total of 21 phenolics were identified and quantified using LC-ESI/MS method including 8 phenolic acids (31.81-33.83 mu g/g DW) and 13 flavonoids (108.10-120.02 mu g/g DW). Quinic acid, protocatechuic acid, epicatechin, hyperoside, and quercetin-3-0-rhamnoside were identified as the predominant compounds. Results so far have been very encouraging and proved that L. creticus seeds are an effective source of phenolics and proteins which could potentially be used for several industrial purposes.
