The novel spermidine alkaloid inandenine was isolated from Oncinotis inandensis Wood et Evans. It was found to be a mixture of two isomers A and B, which could not be separated hitherto. Chemical and mass‐spectrometric investigations revealed that both alkaloids possess the macrocyclic 21‐ring structure 3a and 3b . These two formulae differ only with respect to the position of the ketogroup. Structural elements of the two bases are 9‐oxo‐ and 10‐oxo‐palmitic acid, respectively, and spermidine.
