+"Terpenes and aroma volatiles from rhizomes of Rhodiola rosea L. from Norway have been isolated by both steam distillation and headspace solid-phase micro-extraction coupled with gas chromatography and mass spectrometry analysis. The dried rhizomes contained 0.05% essential oil with the main chemical classes: monoterpene hydrocarbons (25.40%), monoterpene alcohols (23.61%) and straight chain aliphatic alcohols (37.54%). n-Decanol (30.38%), geraniol (12.49%) and 1,4-p-menthadien-7-ol (5.10%) were the most abundant volatiles detected in the essential oil, and a total of 86 compounds were identified in both the SD and HS-SPME samples. Geraniol was identified as the most important rose-like odour compound besides geranyl formate, geranyl acetate, benzyl alcohol and phenylethyl alcohol. Floral notes such as linalool and its oxides, nonanal, decanal, nerol and cinnamyl alcohol highlight the flowery scent of rose root rhizomes." \\

+Geraniol is also main component of the essential oils from rhizomes of two Tibetan Rhodiola species, Rhodiola fastigata (45.3%) and Rhodiola crenulata (53.3%). "Many Rhodiola species such as R. rosea and R. crenulata have been used as traditional medicines for the treatment of long-term illness and weakness due to infection in Tibet and other regions for over 1000 years."\\

+"Due to contradictory results in the literature it was decided to examine the neurophysiological effect of Rhodiola rosea extract on surrogate parameters of cognitive and emotional brain processing in 20 volunteers. Spectral signatures of regional electric brain activity were recorded under control of an Eye-Tracking device, by means of which different challenges were presented... In summary, the extract from Rhodiola rosea modulated cognitive and emotional surrogate parameters indicating improvement of mental processing in a stimulatory and activating sense... intake of Rhodiola rosea extract containing capsules can be regarded as a safe booster of mental activity during cognitive and emotional challenges. It should be mentioned that also other authors already reported on improvement of cognitive performance after repetitive intake of Rhodiola extract ..." \\
