✦ Synopsis
The structure elucidation and complete 1 H-and 13 C-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 HMBC were used for the determination of the structures and NMR spectral assignments.
