Kutki (Picrorhiza kurroa)
- Raw Material Selection: High-grade Kutki roots and rhizomes are sourced from high-altitude Himalayan regions, where the plant is traditionally cultivated for its potent hepatoprotective and antioxidant properties.
- Cleaning and Preparation: Collected rhizomes are thoroughly cleaned with potable water to eliminate soil, dust, and contaminants. Defective, decayed, or non-medicinal parts are removed during the sorting process.
- Extraction Process: The powdered Kutki is loaded into an extraction vessel and subjected to solvent extraction using ethanol-water mixtures. The extraction process may involve maceration or percolation under controlled temperatures and durations to ensure optimal recovery of active constituents.
- Filtration and Concentration: The extract solution is filtered through industrial mesh or filter press systems to remove plant residue and obtain a clean extract.
- Standardization: The final extract is tested and standardized (typically to 4–10% Picroside-I and II) using HPLC or UV spectrophotometry, ensuring consistent potency and therapeutic efficacy.
- Packaging and Storage:The extract is packed in airtight, food-grade containers with proper labeling and stored in cool, dry conditions to maintain its shelf life and stability.
- Quality Control: Comprehensive quality testing is conducted for identity, purity, microbial contamination, heavy metals, and residual solvents as per international standards.
