What Is An Extract
A plant extract is a substance or an active with desirable properties that is removed from the tissue of a plant, usually by treating it with a solvent, to be used for a particular purpose.
Extraction process
The process must generally be simple, fast, economic, in compliance with the local regulation, effective and selective when needed. However, certain steps may require a long time of process.
Crystallization
Crystallization is the (natural or artificial) process of formation of solid crystals precipitating from a solution.
Chromatography
Chromatography is used for separation of mixtures. A mixture dissolved in a “mobile phase” passes through a stationary phase, which separates the analyte.
Hplc - Semisynthesis
Preparative high performance liquid chromatography is similar to analytical HPLC but features increased injected mass with possibility to “stack” injections automatically.
Drying - Before Packing
Drying means putting out the liquid. Dryers may be atmospheric (spray dryer, fluid bed dryer, etc...), or vacuum (belt dryer, tray dryer, etc…).
