Introduction to Rosemary
Rosemary (Rosmarinus officinalis), native to the Mediterranean region, is an aromatic evergreen shrub with slender, pine-needle-like leaves and small, light blue or purple flowers that emit a distinctive camphoraceous fragrance. It is not only a classic culinary herb but also known as a "natural medicine chest" due to its rich bioactive compounds.
Core Ingredients & Benefits
1. Rosmarinic Acid – Powerful antioxidant and anti-inflammatory agent
2. Carnosic Acid – Natural antiseptic that inhibits bacterial growth
3. Eucalyptol (Cineole) – Supports respiratory health and uplifts mood
4. Antioxidant Properties – Neutralizes free radicals and slows aging
In European tradition, rosemary symbolizes "memory and loyalty." Modern research confirms its cognitive-enhancing effects, earning it the nickname "memory herb."
Advantages of Supercritical CO₂ Extraction for Rosemary
Compared to traditional methods (e.g., steam distillation, solvent extraction), supercritical CO₂ extraction offers significant benefits:
1.High Efficiency – Extraction yield up to 1.94% (vs. 0.5%-1% with traditional methods)
2. Eco-Friendly – CO₂ is non-toxic, residue-free, and complies with food/pharmaceutical safety standards
3. Precision Control – Adjustable temperature and pressure allow selective extraction of target compounds
4. Preserves Bioactivity – Low-temperature process protects heat-sensitive components
5. No Solvent Residue – Eliminates the need for post-extraction purification, ensuring higher purity
