Purification of plant extracts
We have purified various plant extracts starting from several hundreds kilograms of plant material. The final products range from standardized solutions to pure solids. Ethanol can be used as solvent. Since every extract has its own complexities, we perform this kind of projects stepwise.
First, we study the process in the laboratory, taking special attention to the scale-up problems that might occur, like filterability, heat stability, etc. This stage produces small samples, so that the customer can check the quality and suggest the improvements that should be made.
Once the main parameters are fixed, several bigger trials are performed to check the scale-up and to supply bigger samples for market exploration.
Finally, we can take care of an industrial production for the commercial quantities.
Besides the industrial resolution processes, we have also developed industrial synthetic processes for D-(−)-α-PhenylGlycine Chloride Hydrochloride and 2- and 4-Hydroxy-Mandelic acids. The latter ones make use of our fractionation technology. Both products are intermediates for the manufacturing of semisynthetic penicillins.
