Abstract:
Phytochemical investigation of the stem bark of Erythrophleum suaveolens yielded four new cassane diterpenoids; 6α-hydroxy-cassamic acid, methyl ester, 4β-carbomethoxy-14-methyltotarol, 6α-hydroxy-nor-cassamine, and 8,9-dehydro-nor-cassamine, along with four known cassane diterpenoids. All structures were elucidated on the basis of one- and two-dimensional NMR, HRMS and ESIMS analysis.
