인동과에 속하는 인동덩굴(Lonicera japonica Thunb., LJ) 추출물이 활성산소의 일종인 glucose oxidase(GO)에 미치는 영향을 배양 C6 glioma 세포를 재료로 알아보았으며, 또한 LJ 추출물의 항산화 효과를 전자공여능(DPPH-radical scavenging activity)을 비롯하여 항산화 효소의 하나인 SOD의 활성과 비슷한 superoxide dismutase(SOD)-유사활성(SOD-like activity), 지질과산화 억제능(lipid peroxidation inhibitory activity) 및 lactate dehydrogenase(DH) 활성에 의하여 조사하였다. 본 연구에서 GO는 처리 농도 의존적으로 대조군에 비하여 배양 C6 glioma 세포의 생존율을 유의하게 감소시킴으로서 세포독성을 나타냈으며(P<0.01), 이 때 XTT50값은 35 mU·mL-1에서 나타났다. 또한, LJ 추출물은 GO에 의하여 감소된 세포생존율을 유의하게 증가시킴으로써 GO의 세포독성을 방어하였다. 한편, LJ 추출물은 전자공여능을 비롯한 SOD-유사활성, 지질과산화 억제능 및 LDH의 활성 감소를 보임으로서 항산화 효과를 나타냈다. 이상의 결과로부터 LJ 추출물은 항산화 효과에 의하여 GO의 세포독성을 유효하게 방어한 것으로 나타났다.

This study was conducted to evaluate the status of habitat distribution, environmental characteristics and plant species growing with Lonicera japonica in its habitats. In the distribution of plant coverage below 30%, it was 84.6% in the inland area and 80.7% in the seashore area. There was similar coverage in both inland and seashore areas. But the average relative coverage in the seashore area was 26.1%, which is a little higher than that of the inland area (22.5%). In the habitats, both inland and seashore areas showed a high distribution ratio below 10 degrees. But among them, inland areas showed a high distribution ratio (62.4%) below 10 degrees, which was about twice as much as the seashore areas (32.2%). Habitat distribution was most often found on the southern slopes in both inland and seashore areas. The average soil pH of Lonicera japonica habitat was 5.2 in the inland areas and 6.9 in the seashore areas. Also, the seashore areas showed little content of P2O5, but high content of K, Mg, Na on the other hand compared to the inland area. Miscanthus sinensis was the highest importance value (16.4) among plants growing with Lonicera japonica in their habitats in both inland and seashore areas. But in the inland areas, Artemisia princeps showed the highest importance value, and Miscanthus sinensis was the highest in the seashore areas.
