Rosmarinic Acid Powder

Rosmarinic Acid Powder is a naturally occurring phenolic acid compound widely distributed in the Lamiaceae family of plants, with particularly high concentrations in rosemary (Rosmarinus officinalis), sage (Salvia officinalis), basil (Ocimum basilicum), and lemon balm (Melissa officinalis). As a hydroxycinnamic acid derivative, rosmarinic acid is one of the most potent natural antioxidants known, exhibiting stronger radical-scavenging activity than vitamin E, caffeic acid, or chlorogenic acid in many assays. It is the primary bioactive marker used to standardize rosemary extracts for nutraceutical, food preservation, and cosmetic applications.

Scientific Note: Rosmarinic acid is a water-soluble phenolic compound, not a major component of rosemary essential oil (which consists mainly of volatile terpenes such as camphor, 1,8-cineole, and α-pinene). The confusion arises because rosemary herb contains both essential oil and rosmarinic acid; however, the acid is extracted via polar solvents (water/ethanol), not steam distillation.

Rosmarinic acid exerts its effects primarily through potent antioxidant, anti-inflammatory, antimicrobial, and immunomodulatory pathways.

1. Potent Antioxidant Activity

Scavenges free radicals (DPPH, ABTS, superoxide, hydroxyl radicals) and reduces oxidative stress.

Protects cells and DNA from lipid peroxidation and oxidative damage.

Often used as a natural alternative to synthetic antioxidants (BHA, BHT) in food and cosmetics.

2. Anti-Inflammatory & Immune Modulation

Inhibits pro-inflammatory enzymes (COX-2, 5-LOX) and cytokines (TNF-α, IL-1β, IL-6).

Suppresses NF-κB activation, reducing chronic inflammation.

Beneficial in nephritis, hepatitis, arthritis, and inflammatory bowel conditions.

3. Antimicrobial & Antiviral Effects

Exhibits broad-spectrum activity against bacteria (e.g., Staphylococcus aureus, E. coli), fungi (e.g., Candida albicans), molds, and viruses (e.g., herpes simplex).

Used as a natural preservative and antibacterial agent in food and personal care products.

4. Skin Soothing & Calming

Reduces redness, irritation, and UV-induced damage; promotes skin repair.

Often formulated in anti-aging, post-sun, and sensitive skin products.

5. Digestive & Appetite Support

Traditionally used to stimulate appetite and enhance gastrointestinal motility.

May help relieve mild digestive discomfort.

6. Hepatoprotective & Allergy Relief

Protects liver cells from toxin-induced damage.

Helps alleviate allergic rhinitis symptoms by inhibiting histamine release.

Our rosmarinic acid powder is produced through a carefully controlled process to ensure purity, consistency, and traceability:

1. Raw Material Sourcing – Fresh rosemary leaves from certified plantations.
2. Inspection & Pre‑treatment – Sorting, washing, drying, and milling.
3. Solvent Extraction – Using food‑grade ethanol or water‑ethanol mixtures.
4. Purification & Refining – Column chromatography or membrane separation to enrich rosmarinic acid content.
5. Concentration – Vacuum evaporation to remove solvents.
6. Drying – Spray drying or vacuum drying to obtain a fine powder.
7. Screening & Milling – Passing through 80‑100 mesh sieves.
8. Quality Testing – HPLC assay for rosmarinic acid content; heavy metals, microbiology, residual solvents.
9. Packaging & Storage – Sealed in moisture‑proof, light‑resistant containers.

Quality + safety: The packaging is packaged in aluminum foil bags, cartons, barrels, etc., according to different requirements. The interior is packaged in double-sealed plastic bags. It has strong moisture and pressure resistance, a uniform color, and can effectively prevent damage.
