The structure of （-）-alloaromadendrane-3β,9β-diol （1） was established by spectroscopic methods, including X-ray analysis that provided its relative stereochemistry. Bioassay showed that （-）-alloaromadendrane-3β,9β-diol （1） possesses anti-pyricularia oryzae P-2b activity with MIC value of 10 μg/m-L.展开更多
