<b>Antimicrobial diterpenoid alkaloids from <i>Erythrophleum suaveolens</i> (Guill. & perr.) Brenan</b>

An investigation of the stem bark of <i>Erythrophleum suaveolens</i> (Guill. & Perr.) Brenan yielded the known amide norcassaide (<b>1</b>) and a new diterpenoid alkaloid named norerythrosuaveolide (<b>2</b>) which was characterized as 7&beta;-hydroxy-7-de...
