“…Very similar total phenolic contents (20.6 and 21.3 mg/100g) were reported by Fratianni et al [ 29 ] in two Italian varieties of grass pea, and by Wang et al [ 21 ].in nine varieties of Canadian grass pea (16.2–37.5 mg/100 g). Higher total phenolic compounds contents in grass pea were reported by Wiszniewska and Piwowarczyk [ 30 ] and Carbonaro et al [ 18 ].…”

Phenolic compounds were extracted from seeds of 30 varieties of grass pea (Lathyrus sativus) into 80% (v/v) methanol. The total phenolics compounds content of the extracts and their antioxidant activity were determined using Folin-Ciocalteu’s phenol reagent and 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and ferric-reducing antioxidant power (FRAP) methods, respectively. Total phenolic contents ranged from 1.88 to 7.12 mg/g extract and 20.3 to 70.3 mg/100 g seeds. The extracts and seeds were characterized using Trolox equivalent antioxidant capacity values of 0.015–0.037 mmol Trolox/g extract and 0.158–0.372 mmol Trolox/100 g seeds, and FRAP values of 0.045–0.120 mmol Fe2+/g extract and 0.487–1.189 Fe2+/100 g seeds. The total phenolics content of grass pea extract was correlated with the results of the ABTS (r = 0.881) and FRAP (r = 0.781) assays. The same correlation was observed between the results of both assays (r = 0.842). Two derivatives of p-coumaric acid were the dominant phenolic compounds of the Derek cultivar of grass pea.

“…This adverse process occurs during isolation of the protoplast, which significantly reduces its viability 46 . According to Wiszniewska and Piwowarczyk, 47 the high TPC in grass pea protoplasts supports the idea that the components of this solution may stimulate protoplasts due to the antioxidant response to oxidative stress during isolation.…”

BACKGROUND: Grass pea (Laithyrus sativus L.) is a rustic plant whose seeds are rich in polyphenols and antioxidants, and it has been consumed as food by human beings since ancient times. This study was conducted in Italy between 2017and 2019 to evaluate, under field conditions, the stability of seed yield, biomass and 1000-seed weight (THS) and to assess the antioxidant composition and activity of 11 grass pea accessions.RESULTS: Analysis of variance revealed significant effects of the environment, accession and accession × environment (A × E) on the yield, above-ground biomass and THS. We found that the environment (year) and A × E explained 52.61% and 23.76% of the total seed yield variation, respectively. No relationship was observed between the yield and the total protein of seeds. Most grass pea accessions showed sensitivity to frost conditions that occurred in the third growing season. The total phenolic content ranged from 50.51 to 112.78 mg 100 g −1 seeds and antioxidant activity ranged from 0.576 to 0.898 mmol Trolox equivalents 100 g −1 seeds and from 0.91 to 1.6 mmol Fe 2+ 100 g −1 seeds in 2,20-azinobis-3-ethylbenzothiazoline-6-sulfonic acid and ferric-reducing antioxidant power, respectively. Among the accessions, the 'Campi Flegrei' and 'di Castelcività' showed the best performance with the highest yield and stability, phenolic content and superior antioxidant activity.CONCLUSION: The results showed that the yield of grass pea was mainly influenced by different climate conditions. This variability in yield, phenolic content and antioxidant activity among different accessions could help breeders and farmers select high-performance accessions for cultivation.

“…In the study of Wang et al (1998), the content of total phenolics in Canadian grass pea ranged from 16.2 to 37.5 mg/100 g. Seeds of Spanish, Italian, French, Polish, and German lines of Lthyrus sativus were characterized by the content of total phenolics that ranged from 20.3 to 70.3 mg/100 g (Rybiński et al, 2018). However, the higher contents of total phenolic compounds in grass pea were reported by Carbonaro et al (2015) and Wiszniewska and Piwowarczyk (2015).…”

Grass pea seeds of 30 varieties from Poland, Slovakia, Czech, Russia, Ukraine, Hungary, Bulgaria, India, Iran, Tunisia, Ethiopia, Canada, and Chile were investigated. Phenolic compounds were extracted from seeds into 80% (v/v) methanol. The total phenolics compounds content of the extracts was determined using Folin-Ciocalteu’s phenol reagent. The antioxidant activity was determined using ABTS and FRAP assays. Total phenolic contents ranged from 2.74 to 10.7 mg/g extract and from 35.9 to 144.7 mg/100 g seeds. The extracts and seeds were characterized using Trolox equivalent antioxidant capacity values of 0.014–0.060 mmol Trolox/g extract and 0.188–0.866 mmol Trolox/100 g seeds, and FRAP values of 0.188–0.866 mmol Fe2+/g extract and 0.541–1.398 Fe2+/100 g seeds. The total phenolics content of grass pea extract was correlated with the results of the ABTS (r = 0.854) and FRAP (r = 0.958) assays. A similar correlation existed between the results of both assays (r = 0.890). Phenolic acids were the dominant phenolic compounds of two cultivars of grass pea. Syringic and sinapic acids had the highest amounts while ferulic, p-hydroxybenzoic, protocatechuic, and p-coumaric acids were present in much lower quantitie. Phenolic acids were present in the form of free compounds, esters, and glycosides.
