SILVA, Tania M. S. et al. Complete 1H and 13C NMR assignments of isojuripidine from Solanum asterophorum Mart.. J. Braz. Chem. Soc. [online]. 2005, vol.16, n.6b, pp.1467-1471. ISSN 0103-5053.

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.

Keywords : Solanaceae; Solanum asterophorum; isojuripidine.
