ResumoThe growth-regulatory activity of 13 tetracyclic diterpenoids with kaurane, beyerane and atisane skeletons isolated from Elaeoselinum species (Umbelliferae) has been tested in six bioassays and their activities were compared with that shown by gibberellic acid, GA3. Seven of the tested substances showed an activity similar or greater than that displayed by GA3 at concentrations 1 to 10 μg ml−1. The most active compounds are ent-15α-angeloyloxykaur-16- ene-3β-yl acetate, methyl ent-18-angeloyloxykaur-16-ene-19-oate, methyl ent-beyer-15-ene-19-oate, methyl ent-14pβ- tygloyloxybeyer-15-ene-19-oate (methyl elasclepiate) and ent-beyer-15-ene-14β,19-diol.
