  • Ten compounds were isolated from the stem barks of Acanthopanax gracilistylus WW Smith (AGS) by steam distillation, they were p-menta-1,5,8-triene, n-butyl isobutylphthalate, p-mentha-1,5-diene-8-ol, 8-hydroxy-p-cymene, myrtenol, trans-(+)-carveol, 1,3-di-tert-butylbenzene, 4-methyl-2,6-di-butylphenol, valencene and verbenone, respectively, characterized by GS-Mass spectra. And we have also extracted and isolated from the MeOH extracts of the stem barks of AGS, two compounds were obtained. On the basis of chemical and spectral evidence, they were syringin(l), ${\beta}-sitosterol(2)$.

  • 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.
