Abstract
The essential oil of the rhizomes of Mongolian Rhodiola rosea L. was investigated by GC and GC/MS. Thirty-six constituents were identified in the oil. The main components in the oil were geraniol (32.3%), myrtenol (15.7%), octanol (13.7%), trans-pinocarveol (11.6%), trans-myrtanol (3.2%), isopinocamphone (2.8%) and piperitone (1.2%). Comparisons are made with Rhodiola rosea rhizome oil from Finland and Norway and oils from other Rhodiola species (R. crenulata, Tibet; R. fastigiata, Tibet; R. yunnanesis, China).
