Effect of dandelion extracts on agglutination with viral hemagglutinin and chicken RBC (cRBC). Four HAU of influenza virus (A/PR/8/34 [H1N1]) were mixed with an equal volume of 2-fold diluted dandelion extracts, ostalmivir (negative control), serum (mice immunized by PR8, positive control) or PBS (virus control) and incubated for 1 h at room temperature. The hemagglutination activity was tested by incubation with 1% (v/v) cRBC in PBS for 1 h at room temperature. We found dandelion extracts couldn't inhibit the viral hemagglutination.
