| titleOfInvention | Method for separating germacrone from Curcuma wenyujin volatile oil |
| abstract | The invention discloses a method for separating germacrone from Curcuma wenyujin volatile oil. The method comprises the following steps: fully mixing an aqueous solution of methyl-beta-cyclodextrin with n-hexane according to a volume ratio of 1:0.5-2, standing, carrying out liquid separation to respectively obtain an upper phase which is a mobile phase and a lower phase which is the stationary phase of a high-speed countercurrent chromatograph; and weighing the Curcuma wenyujin volatile oil, dissolving the Curcuma wenyujin volatile oil in a mixture containing the upper phase and the lower phase according to a volume ratio of 1:1, introducing the above obtained sample, carrying out high-speed countercurrent chromatographic separation, detecting through an ultraviolet detector, collecting corresponding effluents corresponding to peaks in the spectrogram of the ultraviolet detector, concentrating germacrone-containing effluents, and drying to prepare pure germacrone. The method has the advantages of simple operation, less solvent consumption, high efficiency, fastness, strong purposefulness and good separation effect. |
