High Quality Rhodiola Rosea Root Extract Powder Standardized 3% Rosavins 1% Salidroside Hplc Grade
Rhodiola rosea is an adaptogenic plant native to cold, high-altitude regions of Europe and Asia . The "3% rosavins / 1% salidroside" specification indicates the extract has been processed and tested (often via HPLC) to guarantee minimum concentrations of these two distinct groups of bioactive markers. Rosavins (including rosavin, rosin, and rosarin) are characteristic compounds found specifically in R. rosea, while salidroside is a phenylethanoid glycoside also present in the root . This ratio is commonly used in commercial products and was the specific extract type utilized in several animal studies investigating its adaptogenic and central nervous system effects.
