PROBLEM TO BE SOLVED: To provide a method for producing an extract from a plant of the genus Eucalyptus not reducing activity of the active ingredient component when removing a color or a smell, and usable as an antimicrobial agent, quasi medicine, cosmetic, etc. SOLUTION: A color and/or a smell is removed from a solution of an extract prepared by extracting a plant of the genus Eucalyptus with a polar solvent by using at least one kind selected from an adsorbent and an inclusion agent. Activated carbon, celite, silica gel, diatomaceous earth, zeolite, etc., are preferable as the adsorbent. A cyclodextrin is preferable as the inclusion agent. |
