Determination of phenazino-1-carboxylic acid residue in Panax ginseng and soil by high performance liquid chromatography
摘要
Abstract
The residue dynamics were investigated in the field under the conditions of spraying phenazino-1-carboxylic acid 1% suspension concentrate in Panax ginseng and soil, and the final residue in P. ginseng was determined by high performance liquid chromatography. The influences of organic matter content, microbial conditions, temperature and water content on the degradation of phenazino-1-carboxylic acid within the indoor environment were examined. The results showed that the dissipation of phenazino-1-carboxylic acid in P. ginseng and soil were fitted to the first-order kinetic equation, and the half-lives were 3.4 days in the leaf and 3.0 days in the soil. When sprayed at the concentration of 1.8 and 2.7 kg/hm2, the residues of phenazino-1-carboxylic acid in the fresh root and the dry root were all below the detectable level (0.002 mg/kg) in days of 7, 14 and 21. In the simulated indoor environment,phenazino-1-carboxylic acid in the soil could be effectively degraded, which was promoted by the reinforcement effect of microorganism, high organic content, the rise of temperature and increase of water content.关键词
