There are more than 90 species of Rhodiola in the world, and more than 70 species in China are mainly distributed in the alpine zone of the northern hemisphere. There are three commonly used in northern Asia, North Korea, Japan, North America and northern Europe: Rhodiola rosea L. .), Kuree Rhodiola There are more than 90 species of Rhodiola in the world, and more than 70 species in China are mainly distributed in the "alpine zone" of the northern hemisphere. There are three commonly used in northern Asia, North Korea, Japan, North America and northern Europe: Rhodiola rosea (Rhodiola rosea L.), Rhodiola sachalinensis A. Bor and Rhodiola crenulata H. Ohba are generally used in the United States and Europe. Rhodiola crenulata is listed in ChP.
Chinese Pharmacopoeia: This product is the dried root and rhizome of Rhodiola crenulata (Hook. f. et Thoms. ) H. Ohba, a plant in the Sedum family. In autumn, when the flower stems wither, they are excavated, the rough skin is removed, washed and dried in the sun. Rhodiola (Rhodiola sachalinensis A. Bor) and Rhodiola crenulata (Rhodiola crenulata H. Ohba) are mainly used in the United States and Europe, while the Rhodiola rosea is included in the Chinese Pharmacopoeia.

Actives conterminated in USP and CP
The United States Pharmacopoeia USP 38 Rhodiola rosea requires the detection of 6 substances: tyrosol, salidroside, catechin, rosaline, rosa, velovir. While the actives assay in the Chinese Pharmacopoeia 2015 edition is mostly salidroside.
The difference and connection between salidroside and total rosavide in Rhodiola rosea extract:
Both salidroside and total Luosaiwei are extracted from the roots of Rhodiola species.Both of which are wild raw materials, and their functions alike.
Salidroside is the major actives in Rhodiola extract and typical salidrosides ratio is 1%, 2%, 3% , 5% , 10%, 98%, which are mostly extracted from Rhodiola crenulata.
Powdered Rhodiola rosea Extract is prepared from Rhodiola rosea by extraction with hydroalcoholic mixtures. The ratio of plant material to extract is between 1.5:1 and 5:1. It contains NLT 90.0% and NMT 110.0% of the labeled amount of phenylpropenoid glycosides calculated as the sum of rosarin, rosavin, and rosin, and NLT 90.0% and NMT 110.0% of the labeled amount of salidroside, both calculated on the dried basis. It may contain suitable added substances as carriers. The commercial Rhodiola rosea is cultivated in Xinjiang.
