Abstract
Two novel minor quinolizidine alkaloids 4 β-hydroxy-13α-O-(2′-pyrrolylcarbonyl)-lupanine (digittine) and its amino alcohol, 4 β, 13α-dihydroxylupanine, have been isolated from Ethiopian Calpurnia aurea ssp. aurea. The structures of these alkaloids were determined by chemical transformation and by means of spectroscopic techniques (UV, IR, CD, MS, 1H-NMR and 13C-NMR) including two dimensional NMR.This publication has 0 references indexed in Scilit:
