A new acetogenin 2,4-cis-isoannonareticin (2-1) (2,4-cis-bullatacinone) and a known bullatacinone (2,4-trans-isoannonareticin) (2-2) were a pair of isomers epimeric at C-2 which were isolated as two pure natural compounds from Annona reticulata L. by using preparative TLC.Their structures and the relative stereochemistry were elucidated on the basis of the spectral analysis.
