초피첨가 전통장류의 항균 및 항암활성

Abstract

초피나무(Z. piperitum) 열매는 다양한 생리활성을 갖고 있으며, 과피 용매추출물은 세균에 대한 강한 항균활성을 갖고 있어, 간장과 된장제조에 초피를 첨가하여 생리활성효과를 조사하였다. 초피를 간장제조에 1%, 2%, 4% 첨가하여 제조하고, 간장추출물을 식중독균(Sta. aureus, Sal. typhimurium, V. parahemolyticus, E. coli 0157:H7)에 대한 항균활성을 조사했다. 초피를 2% 첨가한 간장은 E. coli 0157:H7과 V. parahemolyticuS 의 생육을 각각 70%와 50% 억제했으며, Sal. typhimurium 과 Sta. aureus 에 대한 항균효과는 농도와 간장제조시기에 따라 40% <TEX>${\sim}$</TEX> 60% 의 생육을 억제했다. 초피된장의 용매추출물에서는 약한 항균활성을 확인할 수 있었다. 초피간장의 추출물을 백혈병세포 U-937에 처리하여 caspase-3 활성으로 항암활성을 조사했다. 그 결과 초피의 량을 1%, 2%, 4% 첨가한 간장의 추출물은 초피를 침가하지 않은 간장보다 caspase-3 활성이 각각 4배, 12배, 15배 활성이 증가하는 것이 확인되어졌다. 이는 초피간장의 추출물이 apoptosis를 유도하는 것을 의미하며, 된장의 용매추출물은 caspase-3 활성에 아무런 영향이 없었다. 초피간장 추출물을 처리한 세포의 죽음이 necrosis인지 apoptosis인지 알아보기 위하여 세포내의 DNA fragmentation을 확인한 결과, 초피간장 추출물을 처리한 세포는 DNA 단편화가 형성되어졌다. 초피틀 1% 첨가한 것에서는 fragmentation을 확인하기 힘들었고, 2%와 4%초피를 첨가한 간장추출물은 DNA fragmentation을 강하게 일으켰다. 초피를 첨가한 간장추출물이 caspase를 활성화시키고, DNA fragmentation을 일으키는 apoptosis 기작에 의해 암세포를 죽음으로 유도하는 초피간장의 항암효과를 입증했다. The fruits of Zanthoxylum piperitum are known as having various physiology vitality, and the abstraction ingredient of the pericarp is also known as having strong antibiotic activities against various bacteria. Therefore, this study was carried out to estimate the effect of physiology vitality when the abstraction ingredient of Z. piperitum was added in soy sauce(Chopi-kanjang) and soybean paste(Chopi-doenjang). For the antibiotic activity against the pathogens of sitotoxism such as Staphylococcus aureus, Salmonella typhimurium, Vibrio parahemolyticus, Escherichia coli 0157:H7, the extracts of the Chopi-kanjang was added 1%, 2%, 4% pericarp of Z. piperitum in the manufacturing process of soy source. According to the results, the growth of E. coli 0157:H7 and V. parahemolyticus were respectively inhibited as 70% and 50% by the Chopi-kanjang added 2% of the ingredient. For the antibiotic effects of the aforementioned Chopi-kanjang against Sal. typhimurium and Sta. aureus, the growth of those pathogens was also inhibited between 40% and 60% according to the manufacturing period of Chopi-kanjang. It was confirmed that the antibiotic activity using the mixture of the abstraction ingredient and Chopi-doenjang was lower than those of Chopi-kanjang. In order to estimate the anticancer activity using by caspase-3 activity, the mixture of the abstraction ingredient of the pericarp of Z. piperitum and Chopi-kanjang was treated to leukemia cells. According to the results, the activities of caspase-3 using the mixture added 1%, 2% and 4% of the abstraction ingredient were respectively increased as much as 4, 12, 15 times comparing with the control which was treated with the soy source only. It could be that the mixture of the abstraction ingredient of the pericarp of Z. piperitum and soy source induced apoptosis, and the mixture of the abstraction ingredient and soybean paste had no effect on the activity of caspase-3. In order to find out the death of the aforementioned cells caused by necrosis or apoptosis, DNA fragmentation in the cell was examined. U-937 cells showed apoptotic DNA fragmentation in the incubation with Chopi-kanjang extract.
