Ent-clerodane derivatives and other constituents from representatives of the subgenus ageratina
(1989)
Ageratina ixiocladon afforded several p-hydroxyacetophenone derivatives and diterpenes including six new ent-clerodanes. Two further species, which are also placed in the subgenus Ageratina, gave p-hydroxyacetophenone ...
Seco-labdanes and other constituents fromOphryosporus floribundus
(1990)
The extract of the aerial parts ofO. floribundus afforded in addition to known compounds 17 new diterpenes, including eightseco-ent-labdanes with a very rare carbon skeleton. The structures were elucidated by high field ...
