The antioxidant properties of heat-treated Hibiscus syriacus was investigated using DPPH test. The stems and the roots of Hibiscus syriacus were examined, respectively. As a result, the extracts of heat-treated Hibiscus syriacus at 100°C for 24 h were more effective than those of non-treated Hibiscus syriacus in reducing the stable free radical 1,1-Diphenyl-2-picrylhydrazyl (DPPH).
