The in vivo anticancer effect of the total flavonoids was assessed in a mouse tumor model bearing H22-induced hepatocellular carcinoma,and cisplatin was used as a positive control.Results：The total flavonoids exerted a powerful inhibitory effect on the three cell lines,with 50%inhibiting concentrations（IC_（50）） of 24.948,31.569 and 6.923μg/mL,respectively.In vivo studies showed that the total flavonoids had dose-dependent inhibitory effects on hepatocellular carcinoma in mice.Conclusion：The total flavonoids from Xianhe Yanling Recipe have potential anticancer activity,and further researches and development are warranted.展开更多
