Özet
Euphorbia peplus L. is a species found in North Africa, Europe, and Western Asia, characterized by significant toxicity capasity and a rich phytochemical content including sterols, flavonoids, and diterpenes. These compounds provide the plant with anti-inflammatory, antimicrobial, anticancer, and allelopathic properties. To expand the limited studies on its antioxidant capacity, this study comparatively analyzed the in vitro antioxidant capacity of E. peplus L. extracts prepared with three different solvents (water, 80% ethanol, methanol). According to the radical scavenging activity results obtained by the DPPH method, the water extract (517.5 ± 0.7 µg/mL) showed higher antioxidant activity than the ethanol (1165 ± 1.2 µg/mL) and methanol (1275 ± 1.4 µg/mL) extracts. When TPC and TFC contents were examined using the Folin–Ciocalteu and colorimetric methods, the highest TPC (158.2 ± 0.07 mg GAE/g) and TFC (14.03 ± 0.02 mg RE/g) values were determined in the ethanol extract. The antioxidant activity, total phenolic content, and flavonoid content of E. peplus L. water extract have been reported for the first time, and it is thought that this study could provide a potential source for solvent selection in determining the active components of antioxidants in future studies of the plant.
