본 연구는 유기질 문화재 보존을 위해 한국 전통 약용식물을 대상으로 항균 및 살충활성을 검증한 결과 황벽나무 열매 추출물이 우수한 활성을 나타냄을 확인하였다. 황벽나무 열매 추출물을 비극성 용매로 분획하여 그 중 가장 활성이 우수한 ethylacetate 분획물을 대상으로 실리카젤 및 Sephadex LH-20 컬럼 크로마토그래피를 실시하고 Prep-TLC를 이용하여 화합물을 순수 분리하였다. 화합물은 UV spectrum 분석 결과 260 nm 파장에서 최대흡수피크가 관찰되었고, $^1H$, $^{13}C$, HMQC, HMBC NMR과 ESI mass spectrum을 이용하여 화학구조를 분석한 결과 (4'-ethyl-2'-methylfuranyl)-6-methoxy-7-methylnona-2E,4E,6Z,8E-tetraenoic acid의 새로운 화합물임을 알 수 있었다.
Antifungal and insecticidal activity of Korean traditional medicinal plants was carried out to develop natural material for the development of organic cultural heritage conservation. As a result, Phellodendron amurense fruit was finally selected as a candidate of antifungal and insecticidal natural material. An novel active compound was purified from the ethylacetate fraction of Phellodendron amurense fruits using silica gel and Sephadex LH-20 column chromatography and PTLC. The compound was obtained as yellow oil form; UV ${\lambda}_{max}$(MeOH): 260 nm. The chemical structure of novel compound was determined as (4'-ethyl-2'-methylfuranyl)-6-methoxy-7-methylnona-2E,4E,6Z,8E-tetraenoic acid on the basis of various NMR experiments including $^1H$- and $^{13}C$-NMR, HMQC, HMBC and ESI-mass spectrum.
