METHOD OF PRODUCING HUMIC SUBSTANCE EXTRACT Russian patent published in 2020 - IPC A61K35/10 C05F11/02 

FIELD: technological processes.

SUBSTANCE: invention relates to production of humic preparations and can be used in pharmaceutics, medicine, cosmetology, as well as in agriculture, namely in plant growing, livestock farming and in reclamation of soil. Method for producing humic substance extract comprises grinding humic-containing material selected from leonardite and/or lignin and/or coal and/or peat and/or sapropel to 0.1–199 mcm fraction, mixing it with water in ratio of raw materials: water from 1:1 to 1:15, treatment of obtained mixture with ultrasound with frequency of 20–40 kHz at temperature of 30–80 °C and pressure of 0.05–0.8 MPa, followed by cooling of obtained extract to room temperature.

EFFECT: invention provides higher biological activity of the obtained extract due to increase of extraction degree and range of extracted active substances from humic-containing raw material with simultaneous reduction of extraction time due to intensification of extraction process.
