Abstract： To establish the method for determination of gallic acid and catechin in the roots of Rosa laevigata(R. laevigata), and analyze the difference in the contents of gallic acid and catechin in roots of R. laevigata from different habitats and different processed methods resources from Guangxi. The contents of gallic acid and catechin of R. laevigata was used as evaluation index, the samples were determined by HPLC, and the data were analyzed by the analysis of variance (ANOVA) and discrimination study carried out based on the hierarchical clustering analysis (HCA) with SPSS 23.0 software. The results were as follows: The contents of gallic acid and catechin in roots of R. laevigata from different habitats and processed methods were different, the content of catechin was higer than that of gallic acid among all sample, the contents of gallic acid and catechin in roots of R. laevigata from the southern habitats (except Guiping, Guigang) were generally higher than those from northern habitats, the contents of gallic acid and catechin were highest in vinegar-processed products. The conclusion displayed that the differences of the contents of gallic acid and catechin in in roots of R. laevigata were mainly the differences of producting habitats and processed methods, the HPLC method is simple and feasible, which could provide a scientific basis for the resources development, quality control and clinical application of R. laevigata.
