Abstract

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.  http://dx.doi.org/10.1590/S0103-50532005000800030.

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.
