Abstract

Lepidoptera (butterflies) extracts, traditionally employed as medicines, have various biological activities. Five species of Lepidoptera (Papilio maackii, Papilio xuthus, Pieris rapae, Eurema hecabe, and Sasakia charonda) were extracted with distilled water (DW), dimethyl sulfoxide (DMSO), ethanol (EtOH), and methanol (MeOH). Each extract was analyzed for anti-oxidant and anti-inflammatory activities using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay method, the ferric reducing ability of plasma (FRAP) test, and a cyclooxygenase-2 (COX-2) promoter assay. The results suggest that Lepidoptera extracts have valuable anti-oxidant and anti-inflammatory properties, supporting the idea that the extracts may serve as a food biomaterial(s) preventing oxidative processes and inflammatory damage.

나비류 추출물은 전통적으로 다양한 활성을 보유하여 의약용으로 사용되어졌다. 5종의 나비(산제비나비[Papilio maackii], 호랑나비[Papilio xuthus], 배추흰나비[Pieris rapae], 남방호랑나비[Eurema hecabe], 왕오색나비[Sasakia charonda])를 이용하여 물, dimethly sulfoxide (DMSO), ehtanol 및 methanol로 추출한 추출물로 항산화 활성 및 Cox-2 promoter assay를 수행하였다. 그 결과 산제비나비의 추출물이 전반적으로 높은 항산화활성을 나타내었으며, Cox-2 promoter assay에서는 호랑나비의 DMSO 분획이 가장 저해활성이 높은 것으로 나타났다. 활성이 높은 추출물을 대상으로 분리 및 정제를 통하여 유용한 식의약 소재로의 기초연구가 더 필요하다.
