He results show that the virus regained infectivity, and the tannins did not direct viricidal effect. Tannins extracted from Polygonum perfoliatum or Archontophoenix alexandrae seeds showed strongly anti-TMV activities separately. TMV virions seems to be aggregated when TMV incubated with the tannins by electron microscope. It seems that TMV coat protein bind to the tannins based on PAGE. Tannins did not reduce infectivity when applied either before or after TMV inoculation. It is proposed that tannins extracted from the 11 species inhibited TMV by binding with TMV coat protein to interfere with recognition site essential for viral coat protein. Tannins extracted from Euphorbia hirta, P. perfoliatum, P. cuspidatum reduce infectivity when applied immediately in N.

MV分别与这11种植物单宁混合后，通过透析除去单宁后，可恢复大部分侵染力，表明单宁对病毒粒体并无直接毒害作用；TMV与杠板归和假槟榔种子中提取的单宁分别混合后，电镜下观察粒体呈现明显的聚集现象；TMV外壳蛋白分别与这两种植物单宁混合后，聚丙烯酰胺凝胶电泳中CP泳带滞后；单宁在病毒接种前施用未降低TMV对叶片的侵染能力；这些结果表明植物单宁对TMV抑制作用可能是单宁与TMV-CP结合影响病毒对叶片侵染位点的识别而降低TMV侵染性，而这种结合是可逆的。
