Rhodiola rosea Extract
Purity Levels
1-3% Rosavin, 1-2% Salidroside by HPLC
Mechotech designs and manufactures turnkey herbal extraction plants for Rhodiola rosea (commonly known as arctic root or golden root), an adaptogenic botanical whose commercial extract is derived from the dried root and rhizome. Genuine Rhodiola rosea standardisation depends on two co-markers assayed together: rosavins, a group of cinnamyl alcohol glycosides that are essentially unique to R. rosea among the many Rhodiola species, and salidroside, a phenylethanoid glycoside shared more widely across the genus. We supply the complete machinery — root/rhizome cleaning and size reduction, hydro-alcoholic extraction, filtration, vacuum concentration, closed-loop solvent recovery, dual-marker standardisation and drying — to process Rhodiola rosea root/rhizome into a consistent extract for the nutraceutical, pharmaceutical, and dietary supplement industries.
Mechotech's Rhodiola rosea plant is engineered around the specific handling and chemistry demands of the root/rhizome: the tough, fibrous raw material is cleaned and mechanically reduced to a uniform particle size to expose surface area for solvent penetration, then extracted using a hydro-alcoholic solvent system tuned to co-extract both the moderately polar rosavins and the more polar salidroside without excessive extraction of tannins and resinous matter that complicate downstream concentration. Because rosavin content is the key marker that distinguishes true Rhodiola rosea from cheaper, morphologically similar Rhodiola species that are sometimes substituted into the supply chain, the plant is built around dual HPLC assay of both rosavin and salidroside at in-process and batch-release stages, not single-marker testing. Constructed in SS 316L with electropolished product-contact surfaces, PLC-SCADA automation and full batch documentation, each plant is delivered as a commissioned turnkey system engineered to the 1-3% Rosavin, 1-2% Salidroside by HPLC specification.

Manufacturing Process
Root/Rhizome Cleaning & Size Reduction
Dried Rhodiola rosea root and rhizome is cleaned to remove soil, stones and foreign matter, then mechanically reduced to a uniform particle size — the tough, woody rhizome requires more aggressive size reduction than soft-tissue botanicals to expose adequate surface area for solvent contact.
Hydro-Alcoholic Extraction
Milled root/rhizome is charged into closed, jacketed SS 316L extractors and extracted with a controlled hydro-alcoholic solvent system under regulated temperature and multiple extraction cycles, tuned to co-extract both rosavins and salidroside efficiently across their differing polarities.
Solid-Liquid Separation & Filtration
The extract slurry is clarified through a plate-and-frame filter press followed by cartridge polish filters, removing fibrous root residue and colloidal matter with minimal loss of the target glycosides.
Vacuum Concentration
The filtered miscella is concentrated in a falling-film / vacuum evaporator, removing ethanol under reduced pressure and controlled temperature to protect the heat-sensitive rosavin and salidroside glycosides from degradation.
Solvent Recovery
A closed-loop recovery system condenses, purifies and recycles the recovered ethanol back into production.
Dual-Marker Standardisation
The concentrate is assayed by HPLC for both rosavin and salidroside independently and adjusted to meet the declared dual specification — 1-3% Rosavin, 1-2% Salidroside — since either marker alone is insufficient to confirm genuine, unadulterated Rhodiola rosea.
Drying
The standardised extract is spray- or vacuum-tray dried to a free-flowing, low-moisture powder suited to encapsulation and blending.
Quality Control & Authentication Release
Finished extract is released after dual HPLC assay, residual-solvent, heavy-metal, microbial, and moisture testing, with full certificate-of-analysis documentation confirming both markers meet specification — the basis for authenticating true R. rosea against substitution with lower-value Rhodiola species.

Dual-Marker HPLC Standardisation
In-process and batch-release assay independently verify both rosavin and salidroside, the authentication basis that distinguishes genuine Rhodiola rosea from substituted or adulterated Rhodiola species lacking real rosavin content.

Root/Rhizome-Optimised Size Reduction
Milling equipment sized for tough, fibrous rhizome material ensures uniform particle size and consistent solvent penetration batch to batch.
Integrated Drying
A matched spray/vacuum dryer produces a free-flowing, low-moisture powder ready for encapsulation and blending.
