Alkaloids isolated from the leaves of atemoya (Annona cherimola × Annona squamosa)


Atemoya is an interspecific annonaceous hybrid between Annona cherimola Mill. and Annona squamosa L. Its phytochemical investigation led to seven alkaloids, including two aporphine (anonaine and asimilobine), three oxoaporphine (lanuginosine, liriodenine and lysicamine) and two proaporphine (pronuciferine and stepharine). These alkaloids were identified by a series of spectrometric methods, mainly MS and NMR (1D and 2D), as well as by comparison with literature data. Our findings showed that this species is an important source of aporphine alkaloids and have high relationship with other Annona species.
