Ten compounds have been isolated from the active EtOAc fraction of the root of Gaulhteria yunnanensis (Franch) Rehd. . Their structures were established as ferulic acid(I),chlorogenic acid(Ⅱ),(+)-catechin(Ⅲ),proanthocyanidin-A2 ( Ⅳ),rutin(V),quercetin(Ⅵ),salicylic acid(Ⅶ),vanillic acid(Ⅷ),gentistic acid(Ⅸ)and protocatechuic acid(X)based on chemical and spectral evidences,N was found for the first time from Ericaceae. The other nine compounds were obtained from Gaultheria L. for the first time.
