The purpose of this study was to evaluate the anti-oxidative effects of fermented Hibiscus syriacus extract on obese mice. The antioxidant experiments were conducted both in vivo and in vitro. The in vitro experiment was measured through the use of nitric oxide (NO) free radical scavenging activity. The results showed that the scavenging activity of the NO free radical in fermented Hibiscus syriacus extract had higher activity than unfermented Hibiscus syriacus extract. The in vivo experiments were divided into a normal dietary group, a high fat dietary group (CON), a high fat dietary + fermented Hibiscus syriacus extract group (FH), and a high fat dietary + unfermented Hibiscus syriacus extract group. These four groups received intraperitoneal administrations for four weeks. Next, the levels of superoxide dismutase (SOD), catalase (CAT), and malondialdehyde (MDA) in a liver homogenate were measured. The results showed that the levels of SOD and CAT in FH were higher than the CON and MDA levels, which were significantly decreased in FH. Consequently, fermented Hibiscus syriacus extract had an inhibitive effect on oxidative stress and a heightening effect on antioxidant enzyme activity in obese mice, suggesting that fermented Hibiscus syriacus extract could be utilized as a useful, natural antioxidant.
