Objectives: The antioxidant and antiproliferative properties of Argemone mexicana and Prosopis cineraria were investigated against Hepatocellular carcinoma (HepG2) and glioblastoma (U87MG) cells. Materials and Methods: Methanolic extracts of the plants were tested for their antioxidant activity using the DPPH and FRAP assays with ascorbic acid as a positive control. The phenolic and flavonoid content of both the plant extracts were evaluated. The anti-proliferative activity of hepatocellular carcinoma and glioblastoma cell lines were estimated by treating the cells with plant extracts by MTT assay. Results: Ascorbic acid showcased the lowest IC50 value at 32.61{\textpm}4.10 μg/mL, followed by A. mexicana (84.02{\textpm}2.46 μg/mL) and P. cineraria (212.65{\textpm}4.77 μg/ mL). Additionally, the FRAP assay revealed the presence of ascorbic acid in both plant extracts, with concentrations of 29.17{\textpm}0.30 μmol AAE/g in A.mexicana and 19.83{\textpm}0.55 μmol AAE/g in P. cineraria. The Total Phenolic Content (TPC) in the stem of Argemone mexicana was determined to be 30.44{\textpm}3.73 mg gallic acid equivalents (GAE) per gram, while that in the leaves of Prosopis cineraria was measured at 6.67{\textpm}0.69 mg of GAE/g. Similarly, the total flavonoid content (TFC) in the stem of A. mexicana was quantified at 16.67{\textpm}1.19 mg of Quercetin Equivalents (QE) per gram, contrasting with the TFC in the leaves of P. cineraria, which registered at 2.17{\textpm}0.59 mg of QE/g. In vitro cytotoxicity was evaluated using the MTT assay, showing a significant decrease in cell viability in both cell lines. The IC50 concentrations were determined as 91.3{\textpm}3.17 μg/mL and 78.43{\textpm}4.16 μg/mL for A. mexicana and 261.43{\textpm}35.16 μg/mL and 108.03{\textpm}2.97 μg/mL for P. cineraria against HepG2 and U87MG cells, respectively. Conclusion: These findings suggest the capacity of both plants as source of antioxidant and carcinostatic agents against hepatocellular carcinoma and glioblastoma.
