摘要
The present invention provides a method of purifying betulonic acid contained the reaction product of organic synthesis of a Jones oxidation reagent and betulin extracted from the bark of a birch, a method of preparing a piperazine betulonic acid amide derivative, which is used as a chemical having an antibacterial function, using the high-purity betulonic acid obtained by the purification method and a derivative prepared by this method, a method of purifying a Boc-lysinated betulonic acid monomer ester contained in the reaction product of organic synthesis of lysine and the high-purity betulonic acid (starting material) obtained by the purification method, and a method of purifying Boc-lysinated betulonic acid contained in the reaction product of hydrolysis of the high-purity Boc-lysinated betulonic acid monomer ester.
