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.

Abstract: The invention provides a methioninase inhibitor to suppress the production of methyl mercaptan that is a causative substance of a bad smell by inhibiting methioninase originated from bacteria, as well as a composition and a food or drink containing the same, wherein the methioninase inhibitor contains an extract obtained from a plant of the family Myrsinaceae, genus Myrsine, preferably Myrsine seguinii as an active ingredient; and further provides a methioninase inhibitor, as well as a composition and a food or drink containing the same, wherein the methioninase inhibitor contains as an active ingredient one or more selected from the group consisting of myrsinoic acid A, myrsinoic acid B, myrsinoic acid C, myrsinoic acid E and myrsinoic acid F; preferably the myrsinoic acid A, myrsinoic acid B, myrsinoic acid C, myrsinoic acid E and myrsinoic acid F are obtained from a plant of the family Myrsinaceae, genus Myrsine, preferably Myrsine seguinii.
