Phytochemical investigation on the leaves of Neolamarckia cadamba led to the isolation of four new indole alkaloids, spirocadambine ( 1 ), dehydraisodihydrocadambine ( 2 ), nitrocadambines A and B ( 3 and 4 ). The structures and relative configurations were established by 1D and 2D NMR spectra. Spirocadambine ( 1 ) represents a new type of screw ring containing indole glucoalkaloids.
