Popis:	From Gutenbergia marginata ten new guaianolides were isolated. Two guaianolides isolated previously from Erlangea inyangana are identical with two further lactones and their structures have been revised. From Bothriocline ripensis ethulia coumarin and two further 5-alkylcoumarin derivatives, one being a chromone, were isolated, while B. longipes and B. eupatorioides gave nine 5-alkylcoumarins and two related compounds. The structures were elucidated by highfield NMR techniques and a few chemical transformations.
