摘要

The present paper reports the isolation of five bibenzyls(1-5), one bibenzyl(1) with phenyl chromanol, one stilbene (6), two 9,10-dihydrophenanthrenes (7-8), two 9,10-dihydrophenanthropyrans (9-10), two lignans (11-12), one flavone(13), and one steroidal ketones (14) from Otochilus fuscus. Except for compound 14, the other isolated constituents are firstly reported from O. fuscus. This finding may support the opinion that phenanthrenes and bibenzyls could be considered as a chemotaxonomic marker for the genus Otochilus.
