How are standardised plant extracts obtained?
Update Time:2015-08-26


The quantities of active ingredients in plants can vary considerably, as a result of the variety of plant used, the part of the plant used (the highest concentrations of active ingredients are usually to be found in a specific part of the plant: root, leaf, stem, flower, fruit) and the environment (climate, season, soil) in which the plant is grown. That’s why the plants are first accurately identified and monitored before they are harvested. During the extraction of the plants, the active ingredients are dissolved. Thereafter, the solvent used (water or alcohol) is evaporated. As a final step, the concentrated extract is analytically controlled and the active ingredients are standardised.
