| Abstract: | Two novel phragmalin type limonoids have been isolated from the bark of Soymida febrifuga and their structures were fully established on the basis of spectroscopic (especially 2D NMR) and spectrometric (mass spectrometry) data, respectively. These novel secondary metabolites possessed β-furyl ring and an ortho ester functionality and their biosynthetic origin was proposed to be the phragmalin-type limonoids. |
