항산화 활성과 피로회복 기능성이 강화된 흑마늘 함유 음료를 개발하기 위하여 5% 흑마늘 추출물과 1%의 생약재 5종 혼합추출물(상황버섯, 황금, 단삼, 뽕잎, 작약)을 70:30(v/v)의 비로 혼합한 흑마늘 복합물(BHF)을 제조하였다. 흑마늘 복합물은 성인의 1일 섭취량을 고려하여 1일 100 ml 섭취 시(BHF1)와 300 ml 섭취 시(BHF2)를 기준으로 실험쥐의 식이에 5주간 혼합 급이하면서 간헐적 강제운동에 따른 체내 지질 성분 및 항산화 효소 활성을 분석하였다. 흑마늘 복합물의 총 페놀화합물 함량은 BHF2가 BHF1에 비해 유의적으로 높았으며, 항산화 활성은 총 페놀 함량에 의존적이었다. 혈중 총 단백질 함량은 운동대조군과 흑마늘 복합물 급이군 간에 유의차가 없었으나, 알부민 함량은 Ex-BHF2군이 유의적으로 높았다. AST 및 ALT 활성은 흑마늘 복합물 급이군이 운동대조군에 비해 유의적으로 감소되었다. 혈청 중성지방, 총 콜레스테롤, LDL-콜레스테롤 및 HTR 수준은 Ex-BHF2군에서 운동대조군에 비해 유의적으로 감소되었다. 간 조직의 총 지질 함량은 흑마늘 복합물 급이군과 운동 대조군간에 유의차가 없었다. 반면에 중성지방과 총 콜레스테롤 함량은 Ex-BHF2군이 타 실험군에 비해 유의적으로 낮았다. 흑마늘 복합물 급이에 따른 간 조직에서 catalase 활성은 Ex-BHF2군만 유의적으로 증가하였으나, SOD와 GSH-px 활성은 흑마늘 복합물의 농도가 많아짐에 따라 유의적으로 증가되었다. 간헐적인 강제운동을 한 흰쥐에서 흑마늘과 생약재 복합물의 급이는 체내 중성지방과 콜레스테롤 함량을 낮추고, 항산화 효소 활성을 증가시킴으로써 산화적 스트레스에 대한 생체 보호가 가능할 것으로 판단된다.
To improve the functionality of black garlic drinks, black garlic extract (5%) and five herb extracts (1%) were mixed in 70:30 (v/v) ratios as BHF1, and BHF2 was prepared using a 3X concentration of BHF1. After the black garlic and herb formulas (BHFs) were administered over the course of five weeks in rats by interval running training, the lipid profiles and the antioxidant enzyme activities were tested. The total phenolic content of the BHFs were significantly higher in BHF2 than they were in BHF1, and their antioxidant activities were dependent upon the total phenolic content. No significant difference was found in the total serum protein levels among the rats in the Ex-con group by interval running training and the rats in the BHFs-fed groups. However, the albumin level was significantly higher in the Ex-BHF2 to Ex-con group. AST and ALT activities significantly decreased in the BHFs-fed groups compared to the Ex-con group. In terms of changes in the serum lipid profiles, no significant difference was found between the specimens that underwent interval running training and those that did not undergo interval running training. Triglyceride levels, total cholesterol, LDL-C, and HTR levels in the serum were significantly decreased in the Ex-BHF2 to Ex-con group. No significant difference was found in the total lipid levels in the livers of the BHFs-fed groups and the Ex-con group. The triglyceride levels and total cholesterol levels in the Ex-BHF2 group were significantly lower compared to another group. Hepatic catalase activity was significantly increased in the Ex-BHF2 group, but SOD and GSH-px activities were significantly increased as the concentration of the BHF. The antioxidant enzyme activities by supplementation of BHFs increased; thus, three intakes of BHF each day could improve antioxidant status against different types of oxidative stress.
