Abstract :
Three new phenanthrenes, thrigonosomone A (1), 6,9-O-dedimethyltrigonostemone (2), and thrigonosomone B (3) were isolated from Trigonostemon lii. Their structures were elucidated by spectroscopic methods. Thrigonosomone A (1) possessed a novel seven-membered cyclic anhydride moiety, and its relative configuration was determined by chemical computation and ROESY experiment. The cytotoxicity of compounds 1–3 was also evaluated.
