- Investigation of the aerial parts of Laggera crispata and Pluchea carolonesis afforded in addition to several known compounds, three new eudesmane derivatives, 3β,4α-dihydroxy-7-epi-eudesm-11(13)-ene, 3α-(2′,3′-dihydroxy-2′-methylbutanoyl)-4,11-dihydroxy-6,7-dehydroeudesman-8-one and 3α-(3′-chloro-2′-hydroxy-2′-methylbutanoyl)cuauhtemone. The structures were elucidated by spectroscopic methods
