title: New Vernolepin Derivatives from Vernonia glabra and Glaucolides from Vernonia scorpioides.
abstract: The aerial parts of VERNONIA GLABRA afforded in addition to vernolepin, vernodalin and vernomenin, four further sesquiterpene lactones derived from vernolepin ( 1), two germacranolides and together with vernodalol the corresponding lactone 9. From VERNONIA SCORPIOIDES two further glaucolides ( 14) and ( 15) were isolated. The structure of the tiglate ( 16) is revised. The structure were elucidated by spectroscopic methods.
