Three new indole alkaloid derivatives, named paniculidines D‒F (1‒3), and six known analogs (4‒9) were isolated from the roots of Murraya paniculata. The structures were elucidated on the basis of comprehensive HRESIMS, UV, IR, and NMR spectroscopic data analysis and comparison with the data reported in literature. The absolute configurations of new compounds were assigned via the determination of
