Paragraph 0047; 0048; 0052; 0053, (2017/10/20)
The invention relates to the technical field of fertilizer, and particularly relates to gossypol derivatives and an application thereof in inhibition of urease activity. The gossypol derivatives have the chemical structural general formula described in the specification, wherein R represents a part except amino in amino acid, and the amino acid is amino acid containing primary amino. The gossypol derivatives take gossypol as an aldehyde group providing reagent and are prepared by modifying the aldehyde group of gossypol with the amino of the amino acid. When the gossypol derivatives are applied in preparation of urease inhibitors, the urease inhibition effect is good, and the IC50 value inhibiting soil ammonia volatilization effect is as low as 1.56*10 mol.L. Compared with a gossypol raw material, the gossypol derivatives have better solubility, are more stable and are convenient to use; and a part of gossypol derivatives have the urease inhibition activity significantly enhanced.
