Abstract

This study investigates the antioxidant and anti-adipogeneic effects of fermented Rhus verniciflua., evaluating the total phenol, total flavonoids contents and antioxidant activity of the fermented Rhus verniciflua as well as assessing the lipid accumulation during adipogenesis of 3T3-L1 cells. Our results demonstrate that the total phenolic and flavonoids contents of fermented Rhus verniciflua were $29.2{\pm}0.12$ GAE mg/g and $20.4{\pm}1.52$ RE mg/g, respectively. The antioxidative activities of fermented Rhus verniciflua were significantly increased in a dose dependent manner on DPPH (1,1-Diphenyl-2-picrylhydrazyl) radical scavenging, ABTS(2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt) radical scavenging, FRAP(ferric reducing antioxidant power)activity, reducing power. In addition, the fermented Rhus verniciflua did not show any cytotoxicity up to 300 ug/mL. However, the anti-adipogenic effect of fermented Rhus verniciflua extract was barely detectable.

본 연구에서는 발효옻의 총 페놀 및 플라보노이드 함량을 측정하였으며, 다양한 항산화 모델(DPPH radical scavenging, ABTS radical scavenging, FRAP activity, reducing power)을 통하여 항산화 활성을 측정하였다. 또한, 3T3-L1 지방세포의 분화과정 중 발효옻에 의한 세포내 지방 축적 억제활성을 평가하여 항비만 활성에 대한 기초자료를 제공하고자 하였다. 발효옻 추출물의 총 페놀 및 플라보노이드 함량은 각각 $29.2{\pm}0.12$ GAE mg/g 및 $20.4{\pm}1.52$ RE mg/g으로 나타났다. 다양한 항산화 평가 모델(DPPH, FRAP, 환원력, ABTS)을 통하여 발효옻 추출물의 항산화 활성을 측정한 결과, 발효옻 추출물의 농도가 증가함에 따라 항산화능이 유의적으로 증가하는 것으로 나타났다. 3T3-L1 지방세포 분화 억제 효과를 확인하기 위하여 지질을 붉은색으로 염색시키는 Oil red O 시약을 통해 3T3-L1 지방세포 내 생성된 중성지방의 양을 측정한 결과, 음성대조군에 비해 $300{\mu}g/mL$ 발효옻 추출물 처리군에서 세포 내 지질 축적량이 감소하였으나 큰 영향은 없는 것으로 판단된다. 발효에 따른 옻나무의 allergy성분을 제거하고 이를 식품소재화 하는 연구는 산업적으로 많은 잠재력을 지닌 것으로 생각된다. 그러나 안전성 및 기능성 구명에 대한 지속적인 연구가 필요하리라 생각된다.
