From aerial parts of Gymnosperma glutinosum two new diterpenoids were
isolated. Their structures were established as (+)-ent-labd-7-en-13S,1
4R,15-triol and (-)-17-hydroxy-neo-clerod-3-en-15-oic acid, by spectra
l means and chemical transformations. The structure of the labdane der
ivative was confirmed by X-ray diffraction analysis.
