Abstract

The anthors have studied to make clear the constituents of the steam volatile oil of Chrysanthemum coronarium L. var. spartiosum Baileg. The oily substance was obtained by steam distillation of the leaves and stems. It was subjected to column chromatography on alumina and eluted with n-hexane, benzene, chloroform, ethyl ether, ethyl acetate and methanol, successively. The following thirteen compounds were identified or tentatively identified: α-pinene, benzaldehyde, camphene, β-pinene, β-myrcene, β-farnesene, benzyl alcohol, p-cymene, linalool, β-phenylethyl alcohol, benzyl acetate, trans-2-(hexa-2, 4-diyn-1-yliden)-1, 6-dioxaspiro [4, 4] non-3-ene and higher aliphatic hydrocarbon C18_??_C29.
