Rosavins are a glycoside compound found in the plant Rhodiola rosea. It is thought to be one of the compounds responsible for the antidepressant andanxiolytic actions of this plant, along with salidroside

Salidroside (Rhodioloside) is a glucoside compound found in the plant Rhodiola rosea. It is thought to be one of the compounds responsible for theantidepressant and anxiolytic actions of this plant, along with rosavin. Salidroside may be more active than rosavin,even though many commerciallymarketed Rhodiola rosea extracts are standardised for rosavin content rather than salidroside.

Rhodiola rosea extract is mainly used in the form of capsules or a tablet, though tinctures are also available. The capsules and tablets often contain 100mg of a standardized amount of 3 percent rosavins and 0.8–1 percent salidroside because the naturally occurring ratio of these compounds in Rhodiolarosea root is approximately 3:1. Authentication as well as potency of golden root crude drug materials and standardized extracts thereof are carried outwith validated RP-HPLC analyses to verify the content of the marker constituents salidroside, rosarin, rosavin, rosin and rosiridin. However, as with manyplant-based remedies, an approved dosage range in relation to the active constituents has officially not been established. In these cases, dosagerecommendations of the individual manufacturers should be followed.
