The neuraminidase is a glycoprotein spike coated on the surface of the influenza virus. Possessing the characteristics of hydrolyzing the virus glycoprotein specific receptors terminal neuraminic acid and adjacent glycosyl connective bond on host cells ,the neuraminidase plays an important role in promoting the release and diffusion the virus. So it has important academic significance to screening neuraminidase inhibitors for prevention and control of influenza. Combining with experimental results on the effects of 96 kinds of single herb on the activity of influenza virus neuraminidase by our...
