Abstract

The purpose of this study was to investigate the biological benefits of apple peel. The antioxidant and anti-inflammatory activities of a 70% ethanol extract of apple peel were examined. The total phenolic compound and flavonoid contents of apple peel were $6.8{\pm}0.5mg$ gallic acid equivalent/g of fresh weight and $3.3{\pm}0.3mg$ catechin equivalent/g of fresh weight, respectively. Antioxidant activity was evaluated by measuring 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. The DPPH radical scavenging activity of apple peel was $18.9{\pm}1.6$, $46.3{\pm}2.3$ and $58.1{\pm}3.9%$ at concentrations of 0.1, 0.5 and 1.0 mg/mL, respectively (p<0.05). The anti-inflammatory effect was investigated by measuring the inhibition of inflammatory enzymes. Apple peel significantly inhibited secretory phospholipase, cyclooxygenase-1, cyclooxygenase-2, and lipoxygenase activity by up to $53.5{\pm}2.3$, $13.4{\pm}1.8$, $64.8{\pm}5.4$ and $44.4{\pm}4.5%$, respectively (p<0.05). Taken together, these findings suggest that apple peel may act as an antioxidant by radical scavenging and may possess potential anti-inflammatory properties for suppressing the activity of inflammatory enzymes. These results also suggest that apple peel can be utilized as a health functional food ingredient possessing antioxidant and anti-inflammatory activities.

본 연구는 사과 과육을 이용한 잼, 음료, 소스, 통조림 등을 가공하는 과정 중 부수적으로 발생하는 사과 과피의 활용을 위해 70% 에탄올 추출물을 이용하여 생리활성을 측정하였다. 이를 위해 사과 과피 추출물의 총 페놀 및 플라보노이드 함량을 측정하고 항산화 활성과 항염 효과를 평가하였다. 사과 과피 추출물의 총 페놀 함량과 플라보노이드 함량은 각각 $6.8{\pm}0.5mgGAE/g$, 플라보노이드는 $3.3{\pm}0.3mgCE/g$으로 나타났다. 항산화 활성을 평가하기 위해 측정한 DPPH 라디칼 소거능은 추출물의 농도에 의존적으로 증가하여 0.1, 0.5 및 1.0 mg/mL의 농도에서 각각 $18.9{\pm}1.6$, $46.3{\pm}2.3$$58.1{\pm}3.9%$로 나타났다(p<0.05). 사과 과피 추출물에 의한 염증 관련 효소 활성 억제 효과를 측정한 결과 $sPLA_2$ 활성은 0.5 및 1.0 mg/mL 농도에서 각각 $26.9{\pm}1.4$$53.5{\pm}2.3%$ 유의적으로 감소하였다(p<0.05). COX-2 활성 억제 효과는 0.1, 0.5 및 1.0 mg/mL의 모든 농도에서 각각 $16.7{\pm}2.6$, $43.6{\pm}3.0$$64.8{\pm}5.4%$로 유의적이었으나 COX-1 활성은 1.0 mg/mL에서만 13.4% 유의적인 저해효과를 나타냈다(p<0.05). LOX 활성 저해 효과 또한 0.1, 0.5 및 1.0 mg/mL 농도에서 각각 $11.9{\pm}1.3$, $27.4{\pm}2.7$$44.4{\pm}4.5%$로 나타나 유의적인 항염 효과를 보였다(p<0.05). 본 연구결과는 사과 과피 추출물이 라디칼 소거능을 통한 항산화 효과를 가지고, 다양한 염증 관련 효소의 활성을 억제함으로써 염증 반응을 전반적으로 조절하고 완화시킬 수 있음을 보여주어, 사과를 이용한 제품의 가공 과정에서 부산물로 생기는 과피를 항산화 및 항염 효과를 가지는 건강기능성식품 소재로 이용할 수 있는 가능성을 시사한다.
