Abstract RU 2102083 C1

FIELD: medicine, oncology. SUBSTANCE: medicinal lignin in the form of an aqueous-alkaline suspension is subjected for ultrasonic oscillation and oxidized with oxygen-containing gas. After reaction mass cooling and separation of solid phase the end product is isolated from an acidified solution. Ultrasonic oscillation is carried out at irradiation power 40.0 ± 0.5 Wt, oscillation frequency 22.0 ± 0.5 kHz for 20-25 min. Oxidation with oxygen-containing gas is carried out at 190-200 C, under pressure 2.0-2.5 MPa for 0.5-3.0 h. EFFECT: decreased tumor proliferation. 2 cl, 5 tbl
