Abstract
Two new quinolizidine alkaloids isolated from bark material of Acosmiu m panamense were identified as 4 alpha-hydroxy-13 beta-methoxylupanine and 3 beta,4 alpha-dihydroxy-13 beta-methoxylupanine by spectroscopic methods. Full H-1 and C-13 NMR spectroscopic assignments are presente d for the closely related alkaloid, 13 beta-methoxylupanine, which als o occurs in this species. (C) 1997 Elsevier Science Ltd.
