    In this study, six extracts of Arabis carduchorum prepared from solvents of varying polarity (water, methanol, ethyl acetate, dichloromethane, and n-hexane) were investigated for their chemical profiles and total phenolic and flavonoid contents (TPC/TFC) using HPLC-MS/MS and spectrophotometric/colorimetric assays, respectively, along with the assessment of their antioxidant and enzyme inhibitory effects. In general, the polar extracts (methanol, water, and infusion) showed higher TPC/TFC than the other extracts (range: 13.73-26.62 mg GAE/g; 2.66-52.95 mg RE/g, respectively). The total antioxidant capacity of the polar extracts ranged from 0.90-1.85 mmol TE/g in phosphomolybdenum assay, while the free radical scavenging potential ranged from 4.36-32.13 mg TE/g and 12.58-67.73 mg TE/g in DPPH and ABTS assays, respectively. While the water and infuse extract inhibited only butyrylcholinesterase (2.68 and 2.39 mg GALAE/g, respectively), the other extracts were found to inhibit both acetyl- and butyryl-cholinesterases (0.96-2.73 mg GALAE/g and 1.86-5.11 mg GALAE/g, respectively). On the contrary, all extracts exhibited anti-tyrosinase (40.24-59.22 mg KAE/g) and anti-amylase (0.09-0.63 mmol ACAE/g) activities. Overall, this study highlighted the effect of solvent polarity on the extraction of bioactive compounds and the biological properties of the extracts of A. carduchorum; hence, the results obtained could be used to guide optimum extraction in future studies.
