Rhodiola rosea
Rhodiola rosea is a succulent perennial of cold mountain and arctic regions, harvested for its root and rhizome. Supply comes from wild collection in Siberia and the Altai and from cultivation in Europe and North America. Brands mostly buy dry hydroalcoholic extracts standardized to rosavins and salidroside, plus some root powder.
Suppliers sell different products under the same name. Specify the one you need.
Dry root extract specified by rosavins and salidroside (a common spec is 3% rosavins and 1% salidroside) by HPLC.
Dried, milled root and rhizome, not standardized.
Salidroside made by synthesis or from other Rhodiola species; it lacks rosavins and is not Rhodiola rosea root extract.
Root from certified organic or cultivated sources, which helps with traceability compared with wild material.
Compare each result with your own specification when the lot arrives.
Keep the extract sealed, cool, dry and out of light. It is hygroscopic and should be resealed promptly after opening. Shelf life or retest date comes from the supplier, with markers re-assayed at retest.
Wild supply is limited and substitution with other Rhodiola species is a known problem, so confirm rosavins on every lot. Record origin (wild or cultivated) and supplier lot.
