General description
Rubus Coreanus Root Extract is an extract obtained from the roots of Rubus coreanus, a plant belonging to the Rosaceae family. The extract is valued for its functional and bioactive properties, which support its use mainly in cosmetics and in medical/traditional contexts. Its complex phytochemical profile makes it of interest for formulations aimed at protection, soothing, and supporting skin physiology.

Chemical composition and structure
The chemical composition of Rubus Coreanus Root Extract includes a variety of bioactive compounds responsible for its functional properties:
Flavonoids: compounds with a phenolic structure, associated with antioxidant activity
Tannins: complex polyphenols with astringent activity
Phenolic acids: aromatic molecules with hydroxyl groups, contributing to oxidative stability
Saponins: glycosides with potential soothing and cleansing effects
Alkaloids: nitrogen-containing compounds, typically in trace amounts, with targeted biological activity
| Compound class | Chemical structure | Functional role |
|---|---|---|
| Flavonoids | Phenolic | Antioxidant |
| Tannins | Complex polyphenolic | Astringent |
| Phenolic acids | Hydroxylated aromatic | Oxidative protection |
| Saponins | Glycosidic | Soothing |
| Alkaloids | Nitrogen-containing | Biological activity |
Physical properties
Rubus Coreanus Root Extract generally presents as:
Appearance: liquid ranging from pale yellow to brown
Odor: mild and earthy, characteristic
Taste: slightly bitter, attributed to tannins and alkaloids
pH: typically 4.5 to 7.0, from slightly acidic to neutral
Solubility: water-soluble, readily incorporable into aqueous systems
| Parameter | Indicative value |
|---|---|
| Color | Pale yellow – brown |
| pH | 4.5 – 7.0 |
| Solubility | Water |
| Odor | Mild, earthy |
Production process
The production of Rubus Coreanus Root Extract involves a controlled sequence of steps:
Harvesting and selection of Rubus coreanus roots
Cleaning to remove soil and contaminants
Drying to reduce moisture content
Crushing and maceration to promote the release of active compounds
Extraction using water or water-based solvents
Filtration and purification to remove solids and impurities
Concentration (optional) to increase the level of active constituents
Sterilization of the final product to ensure microbiological safety
| Step | Objective |
|---|---|
| Drying | Raw material stability |
| Extraction | Recovery of bioactive compounds |
| Filtration | Extract purity |
| Sterilization | Microbiological safety |
