Özet:

 The extraction of Hypericum perforatum L. HP was performed using the Soxhlet extraction method to evaluate its potential as an organic free-radical scavenger in biodiesel-diesel blends. Experimental blendsB100, B20D80, B20D80BHT, and B20D80HPwere prepared, incorporating Hypericum perforatum L. extract at a concentration of 3000 ppm, and compared with butylhydroxytoluene BHT. The antioxidant properties were assessed using differential scanning calorimetry DSC, thermogravimetric analysis TGA, Fourier-transform infrared spectroscopy FT-IR, high-performance liquid chromatography HPLC, and the 2,2-diphenyl-1-picrylhydrazyl DPPH assay. DSC analysis ranked the antioxidant efficiency as D100  B20D80  B20D80BHT  B20D80HP, demonstrating the superior stabilization effect of Hypericum perforatum L. extract. TGA and FT-IR results confirmed enhanced thermal stability, while HPLC identified key phenolic compounds such as rutin, ellagic acid, and kaempferol, which contribute to antioxidant activity. DPPH assays further confirmed the extracts superior free-radical scavenging efficiency compared to BHT. These findings highlight Hypericum perforatum L. as a promising natural antioxidant for improving biodiesel oxidative stability.
