Abstract

Diospyros lotus has been cultivated for its edible fruits, which are considered to have medicinal importance. The aim of this study was to evaluate the antioxidant and antipruritic activities of water-soluble, methanol extract, and ethyl acetate (EA) fractions from D. lotus leaves. The EA fraction showed the lowest $IC_{50}$ vale (DPPH: $5.3{\mu}g/mL$, ABTS: $53.8{\mu}g/mL$). Therefore, we further investigated anti-inflammatory and antipruritic effects of the EA fraction. TNF-${\alpha}$ production increased by PMA plus A23187 treatment was significantly inhibited by the EA fraction in a dose-dependent manner. The EA fraction also inhibited histamine release from rat peritoneal mast cells stimulated by compound 48/80, which promotes histamine release. Furthermore, EA fraction had inhibitory effects on scratching behavior induced by compound 48/80 in Balb/c mice. These results suggest that the EA fraction from D. lotus leaves has potential as ameliorative agent against oxidative stress and pruritus-related disease.

본 연구는 고욤잎 유래 EA 분획물의 항산화 및 항가려움 활성을 조사하였다. EA 분획물은 DPPH 라디칼 소거 활성이 수용성 및 MeOH 추출물보다 매우 우수하였을 뿐만 아니라 합성 항산화제인 BHT보다 현저히 높았다. 또한 ABTS 라디칼 소거 활성도 수용성과 MeOH 추출물뿐만 아니라 Trolox보다 현저히 높았다. 본 연구에 사용된 EA 분획물과 수용성 및 MeOH 추출물은 세포에 대한 독성이 없었다. 또한 EA 분획물은 농도에 의존적으로 활성화된 비만세포로부터 히스타민 방출 억제와 TNF-${\alpha}$ 생성 억제 효과가 있었으며, 같은 농도에서 수용성 및 MeOH 추출물보다 억제 효과가 우수하였다. 더욱이 EA 분획물은 농도 의존적으로 compound 48/80으로 유도된 가려움증을 효과적으로 억제하는 활성이 있었고, 같은 농도에서 항가려움 약제로 알려진 azelastine보다는 그 효과가 낮았지만 수용성 및 MeOH 추출물뿐만 아니라 methysergide보다 우수한 항가려움 효과를 발휘하였다. 앞으로 이러한 항가려움 효과에 대한 EA분획물의 분자적 작용기전을 규명해야 할 필요가 있으며, 고욤잎 유래 EA 분획물은 강력한 항산화 및 항가려움 활성을 지닌 우수한 소재라 사료된다.
