Isojuripidine was isolated from the aerial parts of Solanum astherophorum Mart. Its structure was determined using a combination of homo- (1D ¹H NMR, 13C NMR-HBBD and 13C NMR-DEPT) and heteronuclear 2D NMR techniques (¹H-¹H-COSY, ¹H-¹H-NOESY, HSQC, HMBC), and HREIMS. The unambiguous assignments of ¹H and 13C NMR data of derivatives 3-N,6-O-diacetyl-isojuripidine and 3-N-cinnamoyl-isojuripidine are described.
