Antioxidant Potential of Hypericum spectabile JAUB. ET SPACH

Abstract

Plants have been indispensable products of nature in human history. People used plants for many purposes such as building shelters, smells, flavors, medicines, warming tools, and weapons. In this study, antioxidant and oxidant potentials of Hypericum spectabile JAUB. ET SPACH were determined. Ethanol extract of the plant was extracted in soxhlet apparatus. Antioxidant and oxidant potentials were determined using Rel Assay kits. Free radical scavenging activity was measured using the DPPH method. TAS value of the plant was determined as 4.215±0.038, TOS value as 23.421±0.161 and OSI value as 0.556±0.001. DPPH free radical scavenging activity increased with increasing concentration. It showed 86.74% inhibition at 2 mg/mL extract concentration. As a result, it was determined that H. spectabile has high antioxidant potential.
