Abstract

To develop a nicotine-degrading material (NDM), the natural herbal extract was studied. For the in vitro verification, the herbal extract was mixed into the dilute nicotine solution and the ability of NDM to degrade nicotine into cotinine was measured spectrophotometically. In the in vivo study, the rats in experimental and control groups were orally fed with the herbal extract and water, respectively, for 2 weeks. And then, 3 ㎎/㎏ nicotine was administered to both groups by intraperitoneal injection. In results, the ability of NDM to degrade nicotine into cotinine was shown 2.5 fold higher after 90 min reaction in comparison with the control group. In addition, a decrease of 33% in nicotine concentration and a increase of 57% in cotinine concentration were shown in rat blood. Therefore, NDM was shown to be effective in the conversion of nicotine into cotinine.

본 연구에서는 니코틴분해에 효과가 있는 천연식물 추출물질 (NDM)을 시험관에서 직접 혼합한 경우와 랫트를 이용한 동물 실험을 통해서 니코틴의 코티닌 전이를 조사해 보았다. 니코틴 분해제 (NDM)에 의한 니코틴의 코티닌으로의 분해를 시험관에서 확인한 결과 혼합 90분경과 후 대조군과 대비하여 약 2.5배의 분해능을 보였다. 랫트를 이용한 동물실험에서 NDM의 니코틴분해능 확인결과 혈중 니코틴 농도는 90분 경과 후 대조군 대비 약 33%의 감소를 나타냈고, 코티닌의 혈중 농도는 약 57%의 증가를 나타내었다. 이러한 결과를 통해 NDM이 니코틴 분해에 우수한 효과가 있음을 확인하였다. 본 연구결과에서 알 수 있듯이 기존 알려진 여러 천연식물 추출물들은 니코틴의 대사경로 중 인체에 무해한 코틴닌으로의 전이유도를 촉진하는 물질을 함유하고 있는 것으로 나타났으며, 단일 추출물질이 아닌 복합추출물질로 구성되어 기존의 니코틴 분해제에 비해 탁월한 효과를 보여 주었다.
