Chemical Profiling and Evaluation of Antioxidant Activity of Artichoke (<i>Cynara cardunculus</i> var. <i>scolymus</i>) Leaf By-Products' Extracts Obtained with Green Extraction Techniques.

ABSTRACT: This study aimed to determine the effectiveness of different green extraction techniques (GETs) on targeted bioactive compounds from artichoke leaf by-products using deep eutectic solvent extraction (DESE), supercritical CO₂ extraction (SCO₂E), subcritical water extraction (SWE), and ultrasound-assisted extraction (UAE). Moreover, (HR) LC-ESI-QTOF MS/MS and HPLC-PDA analyses were used to perform qualitative-quantitative analysis on the extracts, enabling the detection of several bioactive compounds, including luteolin, luteolin 7-O-glucoside, luteolin 7-O-rutinoside, apigenin rutinoside, chlorogenic acid, and cynaropicrin as the most representative ones. SWE showed better results than the other GETs (TPC: 23.39 ± 1.87 mg/g of dry plant, dp) and appeared
