This article is dedicated to the comprehensive evaluation of the antioxidant properties of quince seeds and the determination of their antiradical capacity through the application of the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Within the scope of this study, the primary active components contained within quince seeds, specifically phytochemical compounds and natural antioxidants, have been thoroughly examined. The antioxidant characteristics of the seeds were quantitatively assessed using the DPPH assay. The experimental findings clearly demonstrate that quince seeds possess a high level of antiradical activity. Furthermore, the results indicate that these seeds hold significant potential as a natural source of antioxidants, offering substantial benefits for human health and pharmacological applications.
