Rhodiola rosea L. Its unique chemically active constituents are rosavin (the most active), lo linen rosin, rosarin rosarin, rhodiolin and rhodiolin.

Rhodiola rosea with its unique function has caused widespread concern in the food and medicine industry at home and abroad, is now widely used in the treatment of coughing up blood, haemoptysis, pneumonia, cough, women's self-belonging, prevention and treatment of geriatrics, especially in the field of sports medicine, military medicine, aerospace medicine and other areas of important applications.

Uses of Rosavin.

Loxevir has anti-fatigue, anti-hypoxia, anti-microwave radiation, and anti-toxicity effects.

Preparation method of Rosavin.

(1) Rhodiola rosea as raw material, extracted by refluxing with 60%～70% ethanol solution, the extract was concentrated, centrifuged, and the supernatant was passed through a chromatographic column filled with macroporous resin, and washed until the effluent was clarified, and then some impurities were removed by 15～25% ethanol solution.

Firstly, use 15%～25% ethanol solution to elute some impurities, then use 60%～70% ethanol solution to elute out the losevir, collect the eluent of 60%～70% ethanol solution, concentrate, and get the crude extract after drying;

(2) subcritical extraction of the crude extract with methylene chloride as the extractant, the amount of extractant injected is 1~2 times the weight of the crude extract, the extraction temperature is 38~42 ℃, the extraction pressure is 2.3~2.7MPa, the extraction time is 20~40min, and the finished product is obtained by recovering the self-evaporated methylene chloride.
