[Method] The compound TCM was composed of Hedyotis diffusa, Lonicera japonica Thunb, Radix astragali and Glycyrrhiza uralensis. Different dilutions of fluid extract were prepared. Its antiviral effects on NDV were observed through three inoculation ways, first, inoculation with the medicine and NDV mixture which had been incubated at 37 ℃; second, incubating chicken embryo fibroblasts （CEF） with the medicine followed by inoculation with NDV; third, inoculation with N DV followed by incubating CEF with the medicine. The A,= was determined by M]-r [ 3-（4,5-dimethylthiazol-2-yl）-2,5-diphenyltetrazolium bromide） ~ method. Therapeutic indexes were used to evaluate the antiviral effects. [ Result] The minimum effective concentration of the compound TCM which acted through the three ways was 1.0 × 2^-10 1.0 × 2^-8 and 1.0 × 2^-7 g/ml, respectively. The antiviral effects of the compound TCM were the best through inoculation with the incubated medicine and NDV mixture, followed by the second method and the third method. [ Conclusion] The compound TCM can not only kill NDV directly in vitro but also inhibit viral propagation.展开更多
