Background and Aim: In humans, many diseases are associated with the accumulation of free radicals. Antioxidants can scavenge free radicals and minimize their impact. Therefore, the search for naturally occurring antioxidants of plant origin is imperative. Methods: Here, we aimed to investigate the antioxidant and free radical scavenging properties of methanolic extracts from Plantago major, Asperugo procumbens, Fumaria paviflora. Methanolic extract of P. major, A. procumbens, F. paviflora leaf is a potential source of natural antioxidants and serves as an effective free radical scavenger and/or inhibitor. Hence, of P. major, A. procumbens, F. paviflora might be a good plant-based pharmaceutical product for several diseases caused by free radicals. Results: In this experiment, we examined different parts (leaf) of A. procumbens and found that methanolic extract of A. procumbens leaf, which contains large amounts of phenolic and flavonoid compounds, exhibited the highest antioxidant and free radical scavenging. A positive correlation (P-value < 0.005) was observed between phenolic content and free radical (DPPH) scavenging efficiencies. Conclusion: Methanolic extract of A. procumbens leaf is a potential source of natural antioxidants and serves as an effective free radical scavenger and/or inhibitor. Hence, A. procumbens might be a good plant-based pharmaceutical product for several diseases caused by free radicals.
