wherein the amount of the polyphenol compound is from 1 to 50% by weight based on the deodorant composition, and

wherein the amount of the basic substance is such that, when the deodorant composition is dissolved in water to make an aqueous solution thereof, the aqueous solution has a pH of 7.0 or more.

3. The deodorant composition according to claim 2 , wherein the basic substance is at least one member selected from the group consisting of brine, lye, and a bleach.

4. A method for deodorizing a malodor, which comprises applying the deodorant composition according to claim 1 or 2 to a malodor component.

5. The method according to claim 4 , wherein the malodor component comprises a sulfur-containing compound, a lower fatty acid, and/or an amine.

6. A deodorant composition consisting essentially of:

(a) a plant extract containing a polyphenol compound,

(b) a basic substance, and

(c) a metal salt,

wherein the components (a), (b), and (c) are present as an admixture thereof;

wherein the plant extract containing a polyphenol compound is at least one member selected from the group consisting of green tea extract, coffee raw bean extract, apple extract, and grape pericarp extract;

wherein the basic substance is at least one member selected from the group consisting of sodium carbonate, sodium hydroxide, sodium hydrogen carbonate, brine, lye, and a bleach;

wherein the metal salt is at least one member selected from the group consisting of magnesium chloride, calcium chloride, copper chloride, zinc chloride, and manganese sulfate,

wherein a polyphenol compound oxidase is not included in the deodorant composition,

wherein the amount of the polyphenol compound is from 1 to 50% by weight based on the deodorant composition, and

wherein the amount of the basic substance is such that, when the deodorant composition is dissolved in water to make an aqueous solution thereof, the aqueous solution has a pH of 7.0 or more.

7. A deodorant composition consisting essentially of:

(a) a granulated substance which contains a plant extract containing a polyphenol compound,

(b) a basic substance, and

(c) a metal salt,

wherein the components (a), (b), and (c) are present as an admixture thereof;

wherein the plant extract containing a polyphenol compound is at least one member selected from the group consisting of green tea extract, coffee raw bean extract, apple extract, and grape pericarp extract;

wherein the basic substance is at least one member selected from the group consisting of sodium carbonate, sodium hydroxide, sodium hydrogen carbonate, brine, lye, and a bleach;

wherein the metal salt is at least one member selected from the group consisting of magnesium chloride, calcium chloride, copper chloride, zinc chloride, and manganese sulfate,
