Essential Oils in Aerial Parts of Agastache rugosa O. Kuntze.

배초향의 정유성분조성

Contents of essential oil and its composition in aerial part of Agastache rugosa were investigated. Essential oil was obtained from the dried stems, leaves and flowers by steam distillation and fractionated into hydrocarbon and oxygenated hydrocarbon by silica gel column chromatography. Each isolate or fraction was identified by GC and GC-MS. The contents of essential oil were 0.29% in leaves of Agastache rugosa on dry basis, 0.38% in flowers. Major components were ${\beta}-caryophyllene(59.3%)$, limonene(13.1%), ${\delta}-cadinene(10.7%)$ among 13 kinds of components confirmed in hydrocarbon fraction of essential oil isolated from leaves. Also, major components in oxygenated hydrocarbon fraction were methyl chavicol (79.1%) and cis-3(1-propenyl) phenol(4.5%) among 44 kinds components confirmed. The highest content among the components identified was methyl chavicol in both leaves and flowers. On the other hand, limonene, trans-2-hexenal, 1-octen-3-one, 6, 10, 14- trimethyl pentadecane- 2-one and phytol were detected typically in leaves, but jasmone and ${\rho}-methoxyacetophenone$ were detected mainly in flowers with small quantity.

배초향의 지상부로 부터 수증기 증류법에 의해 정유성분을 분리한 다음 silica gel column chromatography에 의해 탄화수소화합물 분획과 함산소화합물 분확으로 나눈후 GC 및 GC-MS에 의해 각 분획의 성분조성을 분석한 결과는 다음과 같다. 1. 배초향의 정유함량은 건물증량으로 잎에서는 0.29%, 꽃에서는 0.38%였으나 줄기에서는 전혀 검출되지 않았다. 2. 잎의 정유에서 분리한 탄화수소화합물 분획에서 확인된 13종의 성분중 주성분은 ${\beta}-caryophyllene(59.3%)$, limonene(13.1%), ${\delta}adinene$ (10.7%) 이었고, 함산소화합물 분획에서 확인된 44종의 성분중 주성분은 methyl chavicol(79.1%), cis-3-(l-propenyl)phenol(4.5%) 등이었다. 3. 잎과 꽃의 정유성분 조성에서 양적으로 가장 많이 함유된 성분은 methylchavicol 이었고, limonene, trans-2-hexenal, 1-octen-3-one, 6,10,14-trimethylpentadecan-2-one 및 phytol등은 잎에서 특징적으로 검출된 반면 jasmone 및 p-methoxyacetophenone등은 양적으로 미량이지만 꽃에서 많이 검출되었다.
