최근 곤충자원은 약용 및 식용으로 활용하려고 많은 연구가 되고 있으며 미래의 자원으로 발전할 수 있는 가능성은 충분하다. 본 연구는 곤충자원 중 칠성무당벌레와 무당벌레를 이용하여 생물학적 활성과 함께 약용 및 식용으로의 활용가능성을 알아보고자 하였다. 생물학적 활성을 알아보기 위하여 이들 추출물을 이용하여 항산화관련 실험인 DPPH, FRAP, linoleic acid 산화 억제실험을 하였으며, 분자 염증에 관련된 유전자인 Cyclooxygena

Insect resources have been widely recognized that seven millions of insects exhibit it own biological activity by whole body or its metabolic intermediates. In order to investigate antioxidant activity and compare the cyclooxygenase-2 promoter activity from insect extract, we tested in vitro antioxidant assays and cyclooxygenase-2 promoter assay in Coccinella septempunctata Linne and Harmonia axyridis extracts have the anti-oxidant and cyclooxygenase-2 inhibition activities, we examined the anti-oxidant assays including DPPH, FRAP and linoleic acid, ana inhibition of cyclooxygenase-2 expression using a cyclooxygenase-2 promoter-inserted stable cell line. We found that Harmonia axyridis Pallas extract had potentials to anti-oxidant activity and inhibited about 25% of cyclooxygenase-2 transcription activity. These findings indicate that Coccinella septempunctata Linne and Harmonia axyridis Pallas extracts could be an useful insect resource for agrobiotechnological purposes.
