Abstract

By comparison of mass fragmentation pattern of each component with two modern MS libraries (NIST and Wiely 6), those were identified to one aliphatic alcohol (3-ethyl-2-methyl-1-pentene-3-ol) and three naphthoquinone derivatives (1,4-naphthoquinone, 5-hydroxy-1,4-naphthoquinone (juglone) and 5-hydroxy-2-methyl-1,4-naphthoquinone (plumbagin)). According to the quantitative study with authentic compounds of three naphthoquinone derivatives, 1,4-naphthoquinone and 5-hydroxy-1,4-naphthoquinone were the major volatile components in the root shell of Juglans mandshurica and their amounts were ca. $54.4{\mu}g/g$ and $21.3{\mu}g/g$, respectively.

가래나무 뿌리껍질에서 단리한 4종의 휘발성 성분을 GC-MS를 이용하여 화학구조를 규명하였다. 각 성분들의 fragment pattern은 NIST와 Wiely 6 스펙트럼과 비교하여 aliphatic alcohol인 3-ethyl-2-methyl-1-pentene-3-ol과 naphthoquinone 유도체인 1,4-naphthoquinone, 5-hydroxy-1,4-naphthoquinone (juglone) 및 5-hydroxy-2-methyl-1,4-naphthoquinone (plumbagin)임을 확인하였다. 정량분석 결과 1,4-naphthoquinone $54.4{\mu}g/g$, 5-hydroxy-1,4-naphthoquinone $21.3{\mu}g/g$, 5-hydroxy-2-methyl-1,4-naphthoquinone $17.1{\mu}g/g$의 함량을 나타냈으며, 1,4-naphthoquinone과 5-hydroxy-1,4-naphthoquinone은 가래나무 뿌리껍질의 주요 휘발성 성분이었다.
