*Rhodiola plants have nearly 100 species in the world. They are mainly distributed in the Himalayas, northwest Asia and North America.
The raw material is the concertrate of rhodiola plant which mainly grows in areas with an altitude of 1600 to 4000 meters, which are cold, dry, hypoxic, strong ultraviolet radiation, and large temperature difference between day and night.
The content of the rhodiola roots and the above-ground parts of the four-year-old alpine rhodiola in different growth periods was measured. The results showed that the appropriate to harvest when fruit is ripe.
Commercial specification are usually standardized to contain 4% salidroside.
