Bioassay-guided fractionation of the extract from the wood-decayed fungus X
ylaria sp. BCC 1067 led to the isolation of five antiplasmodial compounds,
(-)-depudecin, (+)-phaseolinone, (+)-phomenone. 19,20-epoxycytochalasin Q,
and (E)-methyl 3-(4-methoxyphenoxy)propenoate. These structures were elucid
ated using spectroscopic methods, especially NMR analysis.
