초록

본 연구는 발효 무궁화 추출물과 비발효 무궁화 추출물로 나누어 발효하였을 때, 무궁화 추출물의 항산화 활성과 혈액순환 개선에 미치는 효과가 비발효 무궁화 추출물보다 더 높은지 조사하려고 진행되었다. In vitro 실험에서 항산화 활성을 분석하기 위해서 항산화의 생리활성 물질인 polyphenol과 flavonoid의 함량을 비롯한 DPPH radical 소거효능을 측정한 결과 발효 무궁화 추출물과 비발효 무궁화 추출물 모두에서 polyphenol과 flavonoid의 함량이 농도 의존적으로 높았으며 DPPH radical 소거효능도 역시 농도 의존적으로 높게 나타났다. In vivo 생쥐 실험에서는 보통식이군(NOR), 고지방식이군(CON), 고지방식이+발효 무궁화 추출물 섭취군(FHS), 고지방식이+비발효 무궁화 추출물 섭취군(NFHS)으로 나누어 총콜레스테롤(total cholesterol), 중성지질(triglyceride), 고밀도 지질단백질(HDL cholesterol), 저밀도 지질단백질(LDL cholesterol)을 측정한 결과 발효 무궁화 추출물과 비발효 무궁화 추출물은 총콜레스테롤, 저밀도 지질단백질, 중성지질을 저하시키는 효과가 있는 반면 고밀도 지질단백질을 상승시키는 효과가 있었다. 결론적으로 발효 무궁화는 항산화 생리활성 물질을 많이 함유하고 있어 항산화 효과가 있고 혈액순환을 개선하는데 상당한 효과가 있는 것으로 확인되었다.

This study was worked to investigate the antioxidant activity and the blood circulation improvement effect of two Hibiscus syriacus extracts divided into fermented H. syriacus extract and non-fermented H. syriacus extract. As the results of in vitro experiment, both of fermented H. syriacus extract and non-fermented H. syriacus extract had the DPPH free radical scavenging effect and the high contents of polyphenol and flavonoid known as antioxidant components in dose-dependent manner. Six weeks female C57BL/6 mice were divide into four groups and fed high diets for 28 days. Also fermented H. syriacus extract and non-fermented H. syriacus extract was daily intraperitoneal administration for 28 days at 2 mg/kg of body weight of mice. In vivo C57BL/6 mice experiment of normal diet group (NOR), high-fat diet group (CON), high-fat diet plus fermented H. syriacus extract group (FHS) and high-fat diet plus non-fermented H. syriacus extract group (NFHS), each of total cholesterol, triglyceride and low density lipoprotein (LDL) was decreased in both of FHS and NFHS groups, meanwhile high density lipoprotein (HDL) was increased (p<0.01). Conclusion, the results confirmed that H. syriacus containing the high contents of the antioxidant activity components had the significant effects of blood circulation improvement.
