Indeed, identification of the respective bioactive compound(s) is critical not only for drug development but also for quality control during the production of R. rosea mediates all these effects has remained unclear (for more details, please see Discussion). However, whether one and the same chemical constituent of R. Memory-enhancing effects have also been reported in rodents and humans ( Petkov et al., 1986 Panossian et al., 2010 Michels et al., 2018 but see Ishaque et al., 2012). In neither case was behavior towards the odor or the reward affected. rosea extract can enhance the acquisition and the consolidation of such associative memories ( Michels et al., 2018). In bees, acute food supplementation with R. rosea root material or extract enhances odor–reward associative memory in Drosophila larvae and can partially compensate for age-related memory decline in adult flies ( Michels et al., 2018). For example, food supplementation with R. rosea food supplementation in the worm Caenorhabditis elegans and the fly Drosophila melanogaster ( Jafari et al., 2007 Wiegant et al., 2009 Gospodaryov et al., 2013 Arabit et al., 2018), as well as effects related to nervous system function. Contemporary scientific literature has reported increases in life span as a result of R. rosea products have been used for stress relief and the focusing of attention ( Wiegant et al., 2009 Panossian et al., 2010). In accordance with historical reports of the use of root material from this plant to treat headaches and ‘hysteria’ ( Linnaeus, 1749), R. ( Sedum roseum) is a folk-medicine plant of the family Crassulaceae. We discuss whether similar rewarding effects, should they be observed in humans, would indicate a habit-forming or addictive potential. Their rewarding effects can be observed even at low micromolar concentrations and thus at remarkably lower doses than for any known taste reward in the larva. A validation using these as pure compounds confirmed that the correlations were causal. This suggested positive correlations for – among related compounds – ferulic acid eicosyl ester (FAE-20) and β-sitosterol glucoside. rosea root extracts and resultant fractions, a bioactivity-correlation analysis (AcorA) was performed to identify candidate rewarding compounds. rosea root extracts, and did not require activity of dopamine neurons that mediate known rewards such as sugar. This rewarding effect was also observed for R. Rhodiola rosea root samples have an attractive smell and taste to the larvae, and exert a rewarding effect. rosea root samples was accompanied by an investigation of their behavioral impact on Drosophila melanogaster larvae. Here, an analysis of the volatile and non-volatile low-molecular-weight constituents of R. rosea is mediating any one of these effects has remained unknown in most cases. They can increase life span in worms and flies, and have various effects related to nervous system function in different animal species and humans.

Preparations of Rhodiola rosea root are widely used in traditional medicine.
