The synthesis of an organosilicone adsorbent, which can be used in medicine as an enterosorbent for the removal of organic and toxic metabolites from the body obtains a new branched organosilicone polymerous polynuclear adsorbent of high molecular toxins. According to the analysis by Si29NMR method, the adsorbent contains superpositions of at least three silicon signals with values of chemical shifts −；80 ppm, −；100 ppm, −；115 ppm, and ratio of their integral intensities close to 2:2:1. This adsorbent has a high adsorption activity, and the synthesis of its obtaining can reduce labour costs, increase output of the target product in manufacture and reduce their self-cost/net-cost.
