Six further sesquiterpenic lactones (V - X) and one phenylpropane derivative (XI) were isolated from the underground parts of Laser trilobum species. The structure, including the relative and absolute configuration, of five hithero undescribed lactones has been elucidated and described by formulae VI - X.
