摘要：

Objective: To study the inhibitory effects against FM1 and RSV of 11 chemical constituent of Radix Isatidis in vitro and to establish the constituent with antivirus activity.Methods:Inhibitory effects against FM1 and RSV of these chemical constituent were detected by methyl thiazolyl tetrazoliym assay.The antivirus activities of 11chemical constituent were compared when being used inhibitory rate as evaluate index.Results: The inhibitory rate against FM1 were 104.81%,63.53%,49.27%,102.07%,45.40%,60.51%,47.43%,29.20%,24.91%,49.51%,53.00% respectively.The inhibitory rate against RSV were14.47%,12.15%,6.80%,17.89%,44.56% respectively.Conclusion: In these 11 constituents,their effects againsst FM1 are greater than their against RSV.Moreover,the best compositions of FM1 prevention are Indirubin and Vitexin.
