The experimental study is devoted to the quantitative determination of the amount of saponins in the leaves of Arctium lappa growing in the Astrakhan region. The quantitative content of saponins in Arctium lappa raw materials was studied by a spectrophotometric method based on a reaction with sulfuric acid. According to the results of the experiment, it was found that the percentage of the sum of saponins in the leaves of Arctium lappa is 3,11 %, which allows us to conclude that it is possible to use this plant raw material as a basis for the development of medicines with antioxidant activity.
