Objective:
To investigate composition principle of Yinqiao-decoction through experiment of anti-influenza.
Methods:
The effects of different compositions of Yinqiao-decoction on the index of hemagglutinin titre of virus in the lung tissue of mice infected with virus from nose were investigated by orthogonal design.
Results:
According to the hemagglutinin titre of virus in the lung tissue of mice, the necessary effective drugs of Yinqiao-decoction are forsythia suspense, flos lonicerae, fructus arctii, schizonepeta tenuifolia, folium phyllostach lophatheri, glycyrrhiza uralensis, platycodon grandiflorum and mentha haplocalyx, and semen sojae preparatum isn't necessary. There is interaction between forsythia suspense and flos lonicerae, forsythia suspense and fructus arctii, forsythia suspense and schizonepeta tenuifolia, fructus arctii and mentha haplocalyx, schizonepeta tenuifolia and platycodon grandiflorum.
Conclusion:
The optimal combination of Yinqiao-decoction is flos lonicerae, forsythia suspense, fructus arctii, folium phyllostach lophatheri, glycyrrhiza uralensis, mentha haplocalyx of the second level and schizonepeta tenuifolia, platycodon grandiflorum, semen sojae preparatum of the first level.
