미강과 솔잎, 강황 분말을 첨가한 현미에 배양한 장수버섯 균사체 추출물의 생리활성에 관한 연구

Abstract

본 연구는 현미에 미강, 솔잎 그리고 강황을 첨가한 장수버섯 배양물의 전자공여능, 아질산염 소거활성, tyrosinase 저해활성, ACE 저해활성 및 혈전용해 활성을 검토하고자 수행되었다. 전자공여능은 에탄올 보다 열수를 이용한 추출물에서 더 높았다. 아질산염 소거활성은 솔잎첨가 에탄올 추출물에서 가장 높았고 소거활성은 거의 50%였다. tyrosinase 저해활성은 열수이용 추출물에서 가장 높았고 미강, 솔잎 그리고 강황 첨가에 의한 저해율은 장수버섯 열수 추출물에서 각각 72.49%, 87.34% 및 82.75%를 보였다. ACE 저해효과는 모든 물과 에탄올 추출물에서 매우 낮은 효과가 있었다. 혈전용해 활성은 미강, 솔잎, 강황에서 유사하게 높았다. 특히 미강 그리고 강황이 첨가 되었을 때 활성이 plasmin보다 약 10% 증가 되었다. 따라서 동물 실험과 같은 추가 연구가 진행 후, 천연소재로서 식품 및 화장품 산업에 이용될 수 있을 것이다. This study was carried out to examine the electron donating ability (EDA), nitrite scavenging, tyrosinase inhibition, ACE inhibition and fibrinolytic activity of culture extracts from Fomitella fraxinea which was grown added rice bran, pine needles and turmeric in brown rice. Electron donating ability was higher in the extract by hot water than ethanol. Nitrite scavenging activity was the highest from ethanol extract of culture products added to the pine needles, showed the scavenging activity was approximately 50%. Tyrosinase inhibition activity was highest in the extract by hot water, showed inhibition rate of rice bran was 72.49%, pine needles 87.34% and turmeric powder 82.75%, respectively. ACE inhibition activity were very low effective at all water and ethanol extracts. Fibrinolytic activities were similarly strong in the rice bran, pine needles and turmeric powder. Especially, when the rice bran and turmeric powder were added, showed the activities were increased about 10% than plasmin. Therefore, it may be used for the food and cosmetic industry as natural source of bioactive compound after further investigation such as in vivo experiment.
