Abstract
A method for preparing a Eucalyptus extract which decreases the Eucalyptus-specific odor and obtains the effective ingredient in high purity and high yield as a physiologically-active ingredient. An essential oil constituent is removed from the Eucalyptus plant and the residue is extracted with water or an organic solvent aqueous solution. Next, the obtained extraction residue is further extracted with an organic solvent aqueous solution or an organic solvent, whereby Macrocarpal A, Macrocarpal B, and Macrocarpal C contained in the Eucalyptus as a physiological active substance are prepared in higher content than using conventional methods. Further, the extract has improved good taste, appearance, and other desirable properties.
