  • Patent number: 9445605
    Abstract: Provided herein is a method for disinfection or infection control against a non-enveloped virus using a composition including, as an active ingredient, a persimmon extract containing tannin from an astringent fruit of a plant of the genus Diospyros, such as the plant Diospyros kaki. The non-enveloped virus is a non-enveloped virus belonging to the genus Betanodavirus, Aquavirnavirus, Ranavirus, Enterovirus, Mastadenovirus, Vesivirus, or Rotavirus. In certain embodiments, the persimmon extract is prepared by heating a squeezed juice or an extract from an astringent fruit of a plant of the genus Diospyros, or obtained by treating a squeezed juice or an extract from an astringent fruit of the plant of the genus Diospyros with an alcohol, in order to inactivate an enzyme contained therein. The persimmon extract may also contain at least condensed tannin.
