Abstract
Two novel minor quinolizidine alkaloids 4 beta-hydroxy-13alpha- O-(2'-pyrrolylcarbonyl)-lupanine (digittine) and its amino alcohol, 4 beta, 13alpha-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, (1)H-NMR and (13)C-NMR) including two dimensional NMR.Entities:
