Development of burdock leaves dense extract obtaining technology

Optimum conditions of extraction have been selected and a technology for producing a thick extract from the leaves of burdock has been developed. The optimum parameters are: extraction with 40% ethyl alcohol in a ratio of raw material – the extractant as 1:7. The yield under the predetermined conditions is more than 25%, the quantitative content of flavonoids – 1.50%. In the future, it is advisable to standardize the resulting extract, which will create the preconditions for expanding the range of sources of raw materials for herbal remedies with anti-inflammatory action
