To study the chemical constituents in roots of Caragana microphylla. The constituents were isolated by silica gel column chromatography, and their structures were identified by spectroscopic methods and chemical evidence. Eight compounds were identified as beta-sitosterol (1), pseudobaptigenin (2), pentacosanylferulates (3), heptadecanylferulates (4), ferulic acid (5), daucosterol (6), trifolirhizin (7), ononin (8) respectively. Compounds 1, 3-7 were obtained from the plant for the first time, and 3, 4, 5 and 7 were obtained from the genus Caragana for the first time.
