Abstract
Antimicrobial and antioxidative activities on heartwood extractives of domestic species were investigated to develop a natural fungicide or preservative. Six flavanones including pinostrobin, eriodictyol, naringenin, pinocembrin, taxifolin and verecundin were isolated from Prunus sargentii which has been selected due to its high antimicrobial and antioxidative activities among the tested species. According to the results of antifungal test, pinocembrin was evaluated as the highest antifungal compound among the test compounds, which showed 80% of hyphal growth inhibition rate. Antifungal activity of pinocembrin was similar to hinokitiol(
천연물 유래의 보다 안전하고 활성이 우수한 항균 및 항산화물질을 탐색할 목적으로 산벚나무 심재로부터 분리한 pinostrobin, eriodictyol, naringenin. pinocembrin, taxifolin, verecundin의 항균 및 항산화활성을 검정 하였다. 배지점적법을 이용하여 항진균활성을 조사한 결과, pinocembrin(5,7-dihydroxyflavanone)이 공시균주 모두에 대해 80% 이상의 균사생장억제율을 나타내어 가장 활성이 우수한 것으로 나타났으며 그 다음이 naringenin(4',5,7-trihydroxyflavanone), 그리고 verecundin(7-hydroxyflavanone 5-O-
