Abstract
Two new compounds, one new pyrrolidine alkaloid and one new eudesmane-type sesquiterpene derivative, named, respectively, as dictamnaindiol and dictamnadiol, were isolated from the EtOAc soluble fraction of the ethanolic extract from the root barks of Dictamnus dasycarpus. Their structures were elucidated as (3α,4β)-3-(6-ethoxy-6-(4-hydroxyphenyl)methyl)-4-(4-hydroxyphenyl)-1-methyl-pyrrolidin-2-one (1) and (1R, 4S, 7S, 10R)-1,11-dihydroxyl-4,14-epoxy-5(6)-eudesmene (2) on the basis of their spectral and chemical analysis.
