The creation of effective drugs for the prevention and treatment of atherosclerosis is one of the urgent interdisciplinary tasks for modern chemistry and pharmacology. Given the role of hypercholesterolemia in the development of this disease, it is necessary to remove excess amounts of cholesterol from the body. As an alternative to means of lowering total cholesterol and low-density lipoprotein (LDL) cholesterol, the possibility of using carbon enterosorbents for efferent therapy is considered.

Aim. The purpose of the study was to evaluate the sorption capacity of the adsorbents developed by authors in terms of the possibility of cholesterol adsorption.

Methods. Using the spectrophotometric method, the sorption of cholesterol on samples of adsorbents obtained by chemical activation of waste from the processing of lignocellulosic raw materials — dogwood and coffee residue has been studied.

Results. A comparison of sorption isotherms with the isotherm obtained on the industrial adsorbent SORBEX has been performed. It was shown that the adsorption capacity of carbon adsorbents is primarily determined by their porous structure. The highest sorption values (7,3 mg/g) have been revealed by the sorption material obtained by chemical activation of cornel seed, an intermediate position (6,3 mg/g) is occupied by the adsorbent obtained from the coffee residue. Industrial carbon SORBEX has the lowest sorption values (5,3 mg/g).

Conclusions. Calculations by Langmuir’s and Freundlich’s models testify about the accordance of the experimental data to Langmuir’s model. The use of the obtained activated carbons may be one of the effective alternative ways to lower blood cholesterol.
