Abstract
Three new dihydrostilbenes, stilbostemins J-L (1-3), and a new dihydrophenanthrene, stemanthrene F (4), were isolated from the roots of Stemona japonica together with two known bibenzyls, 3,5-dihydroxy-4-methylbibenzyl (5) and 3,5-dihydroxy-2'-methoxy-4-methylbibenzyl (6). Their structures were elucidated by spectroscopic analyses. Compounds 3-6 exhibited strong antibacterial activities against Staphylococcus aureus and Staphylococcus epidermidis.
