The natural preservative "complex Scutellaria baicalensis extract (BHC)" contains Scutellaria baicalensis, Glycyrrhiza uralensis (liquorice), Zizyphus jujube (jujube), and Astragalus propinquus (milk vetch root). BHC has been used as a natural preservative for more than 10 years to increase storage duration and quality of food with strong antibacterial activity. BHC has been added into functional foods as a subsidiary ingredient. However, no studies have been performed to test whether or not BHC affects the activity of main functional ingredients. In this study, we tested whether or not BHC has any effect on the hepatoprotective activity of lactic acid-fermented garlic extract (LAFGE) when formulated in a clinical test supplement. $H_2O_2-induced$ oxidative damage in HepG2 cells was not attenuated by BHC, indicating that BHC had no influence on the protective effect of LAFGE against oxidative damage. Furthermore, BHC had no effect on the hepatoprotective effect of LAFGE against acetaminophen-induced acute liver injury in rats, as indicated by no changes in alanine transaminase and aspartate transaminase levels. In conclusion, BHC, formulated in the clinical test supplement with LAFGE, had no effect on hepatoprotective activity, indicating BHC could be considered as a suitable natural preservative for liquefied functional food materials. 본 연구는 유산균발효 마늘추출물의 간 보호 효능에 대해 천연보존료인 복합 황금추출물이 유산균발효 마늘추출물의 간 보호 효능에 미치는 영향 여부를 확인하기 위해 수행되었다. 복합 황금추출물은 $H_2O_2$에 의한 산화적 손상에 대한 유산균발효 마늘추출물의 간 보호 효능에 있어서 유의적인 영향을 미치지 않았으며, acetaminophen에 의한 급성 간 손상 동물 모델에서 시료에 첨가된 복합 황금추출물은 유산균 발효 마늘추출물의 간 손상 억제 효능에 있어 유의적인 영향을 미치지 않았다. 이상의 결과들을 종합 고찰할 때 복합황금추출물은 기능성 원료의 유효성에 영향을 미치지 않으면서 액상제형 건강기능성식품의 안전성을 확보할 수 있는 천연보존제로 판단되었다.
