마이크로웨이브 추출(MAE)을 이용하여 만가닥버섯을 물, 50% 에탄올, 99% 에탄올로 추출하였으며 마이크로웨이브의 power와 시간에 따라 추출물의 총 폴리페놀 함량, 전자공여 작용(EDA), tyrosinase 저해작용, 아질산염 소거작용의 차이를 관찰하였다. Microwave power를 60∼120 W로 증가시킴에 따라 총 폴리페놀 함량과 전자공여능은 증가하는 경향을 나타내었다. 만가닥버섯의 전자공여능이 90 W에서 평형에 이른 반면에

Functional activities of Lyophyllum ulmarium microwave-assisted extracts under different conditions including electron donating ability, tyrosinase inhibition activity and nitrite scavenging effect were examined. Total polyphenol content increased as increasing microwave power up to 90 W in the water extracts. Electron donating ability increased with microwave power up to 90 W in 50% ethanol extract and 99% ethanol extract. Tyrosinase inhibition activity and nitrite scavenging effect in the extract increased as microwave power increased during extraction. Total polyphenol content increased as extending extraction time up to 5 min in the water extract. But the highest electron donating ability and tyrosinase inhibition activity was obtained after 10 min extraction. Significantly higher total polyphenol content and electron donating ability were found in the water extract whereas greater tyrosinase inhibition activity and nitrite scavenging effect were observed in 99% ethanol extract. The maxium nitrite scavenging effect was found at pH 1.2 and decreased as pH increased.
