[摘要]：The structure elucidation and complete H-1- and C-13-NMR assignments are reported for two new compounds: the ceramide citropremide (1), and the acridone alkaloid citropridone (2). Both of these secondary metabolites were isolated from the stem bark of Citropsis gabunensis. High-resolution mass, IR and UV spectrometry, and NMR experiments including COSY, HMQC, and H M BC were used for the determination of the structures and NMR spectral assignments.
