Quinone-type podocarpanes from the bark of Taiwania cryptomerioides.
Three quinone-type podocarpanes, 3beta-hydroxy-13-methoxy-8,12-podocarpadiene-11,14-dione (1), 18-hydroxy-13-methoxy-8,12-podocarpadiene-11,14-dione (2), and 13-methoxy-8,12-podocarpadiene-2,11,14-trione (3) were isolated from the bark of Taiwania cryptomerioides. Their structures were elucidated using spectral methods.
