Objective： To study the contents of ursolic acid in different habitats of Rabdosia pseudo-irrorata C. Y. Wu. Methods： UV spectrophotometry method was applied to detect the content of ursolic acid of Rabdosia pseudo-irrorata C. Y. Wu. Results： Different fractions of Rabdosia pseudo-irrorata C. Y. Wu were detected; ursolic acid of the leaves was higher than the stems. Conclusion： Ursolic acid contents vary in different habitats of Tibetan medicine Rabdosia pseudo-irrorata C. Y. Wu, and it is necessary to make clear the officinal fractions and to establish quality control standard for Tibetan medicine Rabdosia pseu- do-irrorata C. Y. Wu.
