Three new compounds (1-3), named dasycarine G (1), dasycarether (2), and dasycarester (3), along with seven known compounds (4-10) obtained from the genus Dictamnus for the first time, were isolated from the root bark of Dictamnus dasycarpus. Their structures were elucidated on the basis of spectroscopic data (UV, IR, HR-ESI-MS, 1D and 2D NMR, and CD). In the in vitro assay, compounds 1, 5, 6, 9, and 10 exhibited NO inhibitory effects of LPS-induced BV-2 cells with IC50 values in the range of 10.4 μM to 27.2 μM.
