Abstract

This study was peformed to determine the anticarcinogenic activity of the Solanum tuberosum Peel (SP) on several microorganisms and human cancer cell lines. Among the various solvent fractions of SP, the ethylether Partition layer (SPMEE) showed the strongest antimicrobial activity, ethylacetate partition layer (SPMEA) and butanol partition layer (SPMB) resulted in good antimicrobial activity. We also determined the effect of SP extract and fractions on cytotoxicity, and chemopreventive effect on human cancer cells. The experiment was conducted to determine cytotoxicity of SP partition layers on HepG2, HeLa and MCF-7 cells by MTT assay. Among the various partition layers of SP, SPMEE and SPW were showed the strongest cytotoxic effects on all cancer cell lines. The quinone reductase induced activities of HepG2 cell, the butanol partition layer (SPMB) at a does of 40 $\mu\textrm{g}$/mL was 8.49 times more effective compared to the control value of 1.0. This value was significantly higher than that of previous results using the other materials. Therefore, based on these studies, SP may be developed into a potentially useful antimicrobial and anticarcinogenic agents.

일상생활에서 애용되고 있는 감자는 조리 시 껍질이 거의 폐기되고 있는 점을 감안하여, 폐기 농산물의 재활용의 측면에서 감자껍질(Solanum tubverosum Peel)을 수거하여 추출, 분획한 후 항균 및 항발암 효과를 살펴보았다. 항균성 검사로는 5가지의 균주에 대한 감자껍질의 분획물의 농도별 항균활성을 측정한 결과, 전반적으로 SPMEE에서 가장 큰 항균력을 보였으며, 특히 Pseudomonas aeruginosa 균주에서는 앞서 4가지 균에서는 활성이 없던 수층인 SPMA에서 항균활성이 크게 나타났다 감자껍질의 암세포 증식억제 효과를 MTT assay로 실험 한 결과,3종류의 암세포 HepG2, HeLa 및 MCF- 7세포주에서 모두 ethylether분획층인 SPMEE층에서 암세포 증식억제 효과가 크게 나타났으며 특히 MCF-7의 경우는 저농도 첨가 시부터 SPW층에서 높은 억제효과를 보였다. 또 HepG2세포를 이용한 감자껍질의 분획물의 암예방 QR 유도 활성효과를 본 결과, butanol 분획층인 SPMB에서 괄목할 만큼 높은 QR 유도 활성이 증가되었다. 본 실험 결과, 감자껍질에는 전반적으로 SPMEE층에서 높은 항균성을 보여 항균제로서의 개발가능성이 충분히 엿보이며, 나아가 암세포 증식억제효과도 SPMEE층에서 아주 컸다. SPMB와 SPMEA층에서도 그 효과가 돋보인다. 암을 예방하는 inducer는 SPMB층에 많이 존재하는 것으로 사료되며 이와 같은 연구결과를 기초로 하여 폐기 감자껍질을 이용한 단계적인 생리활성 물질의 분리 동정이 계속 이루어져 폐기식품 활용 및 건강 대체 식품 개발의 연구 대상으로서 기대가 되는 바이다.
