Abstract: Antialergic activities of aqueous extracts of 11 kinds of teas in Yunnan were investigated by measuring their inhibitory effects on hyaluronidase from bovine testis in vitro. The results showed that the teas produced in Yunnan had strong antiallergic effect.Tiancha (Lithocarpus polystachyus) in Yunnan showed stronger antiallergic effect than Tiancha(Guangxi). Phenolic substances in Tiancha were founded to be responsible for antiallergic activity.The ethyl acetate fraction of Tiancha had a very strong antiallergic activity.
