Angelica 속 생약의 정유성분에 관한 연구(Ⅳ) : 강활의 정유성분

Essential oil of the root of Angelica koreana Max. (Umbelliferae) was investigated. Essential oil was obtained from the dried roots by steam distillation and fractionated by column chromatography. Each isolate or fraction was identified by GC, GC-MS and spectral analysis. It was found to contain nine monoterpenes such as ${\alpha}-pinene$(7.0%), camphene, ${\beta}-pinene$, myrcene, ${\alpha}-phellandrene$, ${\Delta}-3-carene$, p-cymene, limonene(2.8%), terpinolene and also found to contain m-cresol(11.6%), citronellol, citral b, methylcinnamate, eudesmol and osthol. 2-Hydroxy-5-methylacetophenone and twelve compounds were tentatively identified.
