method for preparation of lipophilic complex of antimicrobial action

摘要

A method for preparation of lipophilic complex of antimicrobial action by multiple extraction of plant material with organochlorine solvent followed by evaporation of the extract to remove the extractant. As raw materials sweet clover (Melilotus officinalis) medicinal herb and/or white sweet clover herb (Melilotus albus) are used. The extraction is carried out with chloroform at the ratio of total raw material:extractant - 1(10-12), at constant temperature of 55-60 ° C with recirculation of extractant in a closed loop within 28-32 hours.
