Licorice (Glycyrrhiza glabra) Herbal Extraction Plant Process – D-Glycyrrhizic Acid
- Raw Material Selection: High-quality Lodhra bark is sourced from sustainable forests or certified cultivators. The bark is selected based on thickness, age, and its richness in symplocos alkaloids, the key bioactive compounds responsible for its therapeutic properties.
- Cleaning and Preparation: The bark is thoroughly cleaned using water sprays and mechanical brushes to remove soil, grit, and impurities. It is then manually sorted to remove any decayed, pest-affected, or inferior-quality material.
- Extraction Process: The powdered material is loaded into stainless steel extraction vessels and subjected to hydroalcoholic extraction (water + ethanol or methanol) under controlled temperature and agitation. This solvent system helps in effective extraction of the alkaloid compounds.
- Filtration and Concentration: The extract is filtered through multi-layer filtration systems or pressure filters to eliminate any solid residues, producing a clear liquid extract.
- Standardization: The final product is standardized to a specified percentage of total alkaloids using HPLC or UV spectrophotometry, ensuring batch-to-batch consistency for therapeutic and cosmetic use.
- Packaging and Storage: The standardized extract is packed in airtight, food-grade containers with desiccants and UV protection, then stored in cool, dry warehouses to maintain potency and shelf life.
