Abstract

A new flavone, lycopodone (1), together with other three known flavonoids tricin (2), tricetin 3’,4’,5’-OMe (3), 5,7,4’-trihydroxy-3’- methoxy flavone (4), were isolated from the fern Lycopodium japonicum. The structure of 1 was established on the basis of spectral measures. Compounds (1) and (2) showed moderate antitumor activity.
