Obtaining of the burdock leaves extract
The process of burdock leaves extraction by filtration extraction has been studied. On the basis of the experiments it has been found that the highest yield of the extract of burdock leaves is observed under the following conditions: the mass of the loaded raw materials - 100,0 g; extract-ant - 40% ethanol; extraction temperature - 20±2 °C; extraction rate - 3-4 ml/min; the ratio of "raw materials: extractant" (DER) - 1:5.The obtained extract is to be used subsequently as an active pharmaceutical ingredient in the soft dosage forms of anti-inflammatory action.
