Rhodiola Rosea

Rhodiola contains a number of potentially active compounds, including phenylpropanoids(Rosavin, Rosin, rosarin); Phenylethanol derivatives(Salidroside, tyrosol); Flavonoids (Rodiolin, rodionin, rodiosin, acetylrodalgin, tricin), monoterpenes(Rosiridol, rosaridin); triterpenes (daucosterol, beta-sitosterol); and phenolic acids( chlorogenic, hydroxycinnamic, and gallic acids). The presence of rosavin distinguishes the species R. Rosea from other rhodiolas, and many products are standardized to rosavin content to ensure that they contain the proper species.
