Abstract
The GLC analysis has been carried out of the products of the vapor-phase hydrogenation of the unsaturated lactoens ofInula helenium L. Tetrahydroalantolactone has been detected for the first time in elecampane rhizones and roots. During the vapor-phase hydrogenation of the compounds being analyzed in the presence of a Ni catalyst, a migration of the exocyclic double bond of isoalantolactone and of dihydroisoalantolactone was observed.
