저령추출물의 항암, 항산화 및 항균효과
Antitumoral, Antioxidant and Antimicrobial Activities of Solvent Ftactions from Grifola umbllatus
초록
본 연구에서는 다양한 기능성을 가지는 저령을 80% methanol로 추출한 후 그 농축액을 ehyl acetate와 water로 순차 분획하고, 각 분획물을 이용하여 인간유래 위암세포인 SNU668의 생장 저해 효과와 항산화 효과 및 각종 위장질환의 원인균으로 보고된 H. pylori에 대한 항균활성을 조사하였다. 인간유래의 위암세포인 SNU668에 대한 저해 효과는 methanol fraction 1 mg/
Grifola umbellatus was extracted using methanol, and the extract was further fractionated by water and ethyl acetate. Assay of each fraction with MTT [3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium-bromide] revealed significant cytotoxicity effect of the methanol extract of Grifola umbellatus against human gastric cancer cell but not normal human lymphocytes. The methanol extract showed the highest antioxidant activity as well. Antimicrobial activity of Grifola umbellants against Helicobacter pylori was higher in method extract than in other fractions. Grifola umbellatus had a significant inhibitory effect on Helicobacter pylori reducing both its growth and urease activity. These results show that the methanol extract of Grifola umbellatus possesses therapeutic potential on gastric diseases.
