Complete ¹H- and 13C- Resonance Assignment of Methyl 2alpha, 3beta, 24-Tri-O-acetylurs-12-en-28-oate and Methyl 2alpha, 3beta, 24-Tri-O-acetylolean-12-en-28-oate by NMR Spectroscopy

Authorship SCIMAGO INSTITUTIONS RANKINGS

The complete ¹H and 13C chemical shift assignments of extended hydrogen spin systems in triterpenoid derivatives (methyl 2alpha, 3beta, 24-tri-O-acetylurs-12-en-28-oate and methyl 2alpha, 3beta, 24-tri-O-acetylolean-12-en-28-oate) was accomplished making use of one and two dimensional NMR techniques (HMBC, HMQC, COSY and NOESY).

triterpenoids; complete ¹H and 13C-NMR signal assignments; 1D NMR; 2D NMR (¹H x 13C-HMBC, ¹H x 13C -HMQC, ¹H x ¹H-COSY, ¹H x ¹H-NOESY)
