    摘要: An antimicrobial composition containing a wasp extract, and more particularly, a broad-spectrum antimicrobial composition containing, as an active ingredient, an ethyl acetate fraction recovered by sequential organic solvent fraction of an ethanol extract of Vespa velutina nigrithorax or Vespa simillima simillima Smith. The Vespa velutina nigrithorax extract or the V. simillima simillima Smith extract exhibits excellent broad-spectrum antimicrobial activity against gram-positive bacteria, gram-negative bacterial and fungi, and thus may be used for pharmaceutical compositions, health functional foods, cosmetic compositions, animal feed compositions, additives for food, cosmetics or animal feed, various detergents and various cleansers. In addition, the extract has excellent heat stability, and does not lose its activity even under an acidic condition of pH 2.
