Abstract
The present invention relates to a composition for suppressing neuraminidase activity comprising a geranylated flavonoid derived from Paulownia tomentosa as an active ingredient. The Paulownia tomentosa extract and the geranylated flavonoid isolated therefrom exhibit an effect in significantly suppressing neuraminidase, which is an enzyme that plays an important role in the occurrence of pathogenic viral and bacterial infections and of the inflammation that accompanies such infection, and thus the Paulownia tomentosa extract or the geranylated flavonoid isolated therefrom can advantageously be used as an active ingredient in a composition for inhibiting neuraminidase activity.
