The results indicated that a temperature of 122 °C and an extraction time of 17 min are optimal. These optimized conditions were subsequently applied to green pea derived samples, including pea hulls, flour, protein isolates, and whole peas, with TPC values ranging from 2020 to 4050 mg/kg dry weight. High-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS) determined a total of 18 distinct phenolic compounds, including compounds that were allied to flavonoids, phenolic acids and stilbenes.

Herein, a ratiometric electrochemical aptasensor was developed to address these issues by integrating aptamers for indirect recognition and internal reference for signal calibration.

Among these, YLWVGA demonstrated the strongest antioxidant activity, likely attributed to its lowest CDOCKER energy, additional key binding sites and hydrogen bonds with Keap1 compared to other peptides, along with a T-type π-π stacking interaction. This resulted in reduced Reactive Oxygen Species (ROS) and Malondialdehyde (MDA) levels, as well as decreased liver injury markers, indicating improved cellular integrity.
