Bark of Ocotea pulchella contains, besides 1-(p-methoxybenzoyl)-6,7-methylenedioxyisoquinoline, 1-(hydroxy-p-methoxybenzyl)-6,7-methylenedioxyisoquinoline and their 1,2-dihydro-derivatives, 11-eudesmen-4α-ol and ...

Eudesmane-type sesquiterpenoids 3α-(2,3-epoxy-2-methylbutyryloxy)-4α-formoxy-11-hydroxy-6,7-dehydroeudesman-8-one (1) and 3α-(2,3-epoxy-2-methylbutyryloxy)-4α,7α,11-trihydroxyeudesman-8-one (2), together with 10 known ...

The essential oil from leaves of Guarea guidonia was subjected to chromatographic separation procedures to afford nine sesquiterpenes; two of them are new eudesmane derivatives. The chemical structures of the obtained ...

The aerial parts of Oxyphyllum ulicinum afforded, in addition to known compounds, 15 new germacrane derivatives with a 1β, 10α-epoxide, a carboxyl group at C-4, and different ester groups at C-9 and C-14. From the aerial ...
