OBJECTIVE To investigate the chemical constituents of Caragana rosea Turcz.. METHODS The compounds were separated with chromatography techniques and their structures were elucidated on the basis of spectroscopic evidence and physiochemical properties RESULTS Five phytosterols and one triterpenoid were isolated from the chloroform fraction of the stems of Caragana rosea They were identified respectively as 7α-hydroxysitosterol (1), 7β-hydroxysitosterol (2), 5α-stigmastane-3β,6α-diol (3), β-sitosterol (4), daucosterol (5) and oleanolic acid (6) CONCLUSION All of the compounds were isolated from Caragana rosea Turcz for the first time.
