| Abstract: | The chemical composition of the terpenoids of the essential oil ofLedum hypoleucum growing in the Far East has been studied. It differs fromL. palustre by a larger amount of compounds of the bisabolane series in the essential oil. Among the monoterpenoids, p-cymene,  -phellandrene, and ascaridole predominate. The main components of the sesquiterpenoids are ar-curcumene and ar-turmerone, now found for the first time inLedum essential oils.Tomsk State Medical Institute.
