OBJECTIVE: To reveal the pharmacological activities of the components for their further utilization and development by studying the chemical constituents of Citrus changshan-huyou. METHOD: The structures were determined by repeated silica gel chromatographic separation and spectral analysis. RESULT: Five compounds were obtained, and identified as 3-oxo friedelin (I), limonin (II), beta-sitosterol (III), 8-(2',3'-dihydroxy-4'-methylbutane)-7-methoxycoumarin (IV), sucrose (V). CONCLUSION: The five compounds were obtained from this plant for the first time.
