Abstract

Alkaloidal extracts of two species from the genus Pearsonia yielded several quinolizidine alkaloids. Amongst these were four new esters of hydroxylated lupanines, cajanifoline (3β-hydroxylupanine-13α-O-angelate), sessilifoline (3β-hydroxylupanine-4α-O-angelate), pearsonine (3β,8α-dihydroxylupanine-13α-O-angelate) and cryptanthine (8α-hydroxylupanine-13α-O-angelate). The correct structure for a hydroxylated lupanine (previously believed to be nuttalline), namely 3β-hydroxylupanine, is reported.
