Potential Antioxidant Compounds from the Spores of <i>Dicranopteris linearis</i> and the Branches of <i>Averrhoa bilimbi</i>.

ABSTRACT: This study focused on bio-guided isolation based on antioxidant activities from Dicranopteris linearis spores and Averrhoa bilimbi branches. The total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activities of the extracts were determined. For D. linearis spores, the ethyl acetate (EA) extract exhibited the highest TPC (120.13 ± 0.04 mg GAE/g) and TFC (21.94 ± 0.30 mg QE/g), along with strong DPPH antioxidant activity (96.3 ± 0.3% inhibition, IC₅₀ of 39.4 ± 0.3 µg/mL). For A. bilimbi branches, the n-hexane-ethyl acetate (HEA) extract showed the highest TPC (165.21 ± 0.24 mg GAE/g) and TFC (26.20 ± 0.01 mg QE/g), with significant DPPH antioxidant activity (89.6 ± 0.7% inhibition, IC₅₀ of 39.7 ± 1.9 µg/mL).
