초록

본 연구의 목적은 비만 쥐에서의 발효 무궁화 추출물의 항산화 효과를 평가를 위해 수행되었다. 항산화 실험은 in vivo와 in vitro 둘 다 진행하였다. In vitro 실험은 산화질소 자유 라디칼 소거활성을 사용하여 측정하였다. 발효 무궁화 추출물에서의 산화질소 자유 라디칼 소거활성은 비발효 무궁화 추출물보다 높게 나타났다. In vivo 실험은 정상식이군(NOR), 고지방식이군(CON), 고지방식이+발효 무궁화 추출물군(FH)과 고지방식이+비발효 무궁화 추출물군(NFH)로 나눴고, 4군은 4주 동안 복강투여하였다. 그리고 간 균질액의 SOD, CAT, MDA 수준을 측정하였다. 그 결과 FH군의 SOD와 CAT 수준은 CON군보다 높게 나타났으며, FH군의 MDA 수준은 CON군에 비해 현저하게 감소하였다. 결론적으로 발효 무궁화 추출물은 비만 쥐에서의 산화적 스트레스 억제 효과와 항산화 효소 활성 증가 효과를 가지며, 유용한 천연 항산화제의 원료로 사용할 수 있음을 제안한다.

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.
