Process Description
Raw Material Preparation
Fresh or dried Tulsi leaves are cleaned, sorted, and cut into uniform sizes to improve extraction efficiency while preserving delicate phytochemicals.
Steam Distillation (Optional)
Where Tulsi Essential Oil production is required, fresh leaves undergo steam distillation before extraction of the spent biomass.
Benefits include:
- Premium essential oil recovery
- Designed to support commercial viability
- High-quality aromatic oil
Hydro-Alcoholic Extraction
Prepared Tulsi biomass is extracted using pharmaceutical-grade hydro-alcoholic solvents under optimised process conditions.
The extraction system provides:
- High ursolic acid recovery
- Retention of antioxidant compounds
- Uniform extraction efficiency
Filtration
The crude extract is clarified through pressure filtration systems to remove insoluble plant materials before downstream processing.
Vacuum Solvent Recovery
The clarified extract enters high-efficiency vacuum evaporators where extraction solvent is recovered, purified, and recycled.
Benefits include:
- Designed for efficient operation
- Reduced environmental impact
- Enhanced safety
Vacuum Concentration
The extract is concentrated under low-temperature vacuum conditions to preserve heat-sensitive phytochemicals and antioxidant activity.
Membrane Clarification
Microfiltration and ultrafiltration systems improve extract clarity while retaining valuable active compounds.
Advantages include:
- Better purity
- Improved stability
- Lower product losses
- Enhanced downstream efficiency
Purification & Standardisation
Advanced purification systems standardise the extract according to customer requirements.
Typical specifications include:
- Ursolic Acid
- Eugenol
- Rosmarinic Acid
- Total Polyphenols
- Moisture
- Bulk Density
- Particle Size
Spray Drying
The purified extract is spray dried into a free-flowing powder suitable for capsules, tablets, sachets, beverages, and herbal formulations.
Quality Standardisation
Each production batch is analysed for:
- Ursolic Acid
- Eugenol
- Rosmarinic Acid
- Total Polyphenols
- Essential Oil Content
- Moisture
