摘要： 为探究多黏类芽孢杆菌对人参不同部位农药残留及人参皂苷含量影响，通过气相色谱法、高效液相色谱法分别对人参内生多黏类芽孢杆菌处理前后人参不同部位农药残留及人参皂苷含量测定，比较其差异。结果显示：多黏类芽孢杆菌对5个部位农残降解率由大到小依次为芦头87.25%、须根69.87%、支根69.02%、木质部54.28%、韧皮部32.69%，对照组各部位农残降解率仅为7.58%~13.33%（P<0.05）。多黏类芽孢杆菌对人参各部位的9种人参皂苷加合值的含量累积效果由大到小依次为须根21.34%、芦头12.00%、支根9.03%、韧皮部8.60%、木质部8.18%（P<0.05）。结果表明，人参不同部位的农药残留与人参皂苷含量均有不同分布，多黏类芽孢杆菌对5个部位农残降解率以及9种人参皂苷的含量影响显著(P<0.05)。

Abstract: In order to explore the effect of Bacillus polymyxa on the pesticide residues and ginsenoside content in different parts of ginseng, the pesticide residues and ginsenoside content in different parts of ginseng were determined by gas chromatography and high performance liquid chromatography before and after treatment with Bacillus polymyxa. The results showed that the degradation rates of Bacillus polymyxa on the five parts of pesticide residues in descending order were 87.25% of rhizome, 69.87% of fibrous roots, 69.02% of branch roots, 54.28% of xylem, and 32.69% of phloem. The degradation rate was only 7.58%-13.33% (P<0.05). The cumulative effects of Bacillus polymyxa on the content of the 9 ginsenosides in each part of ginseng in descending order were 21.34% fibrous root, 12.00% rhizome, 9.03% branch root, 8.60% phloem, 8.18% xylem (P<0.05). The results showed that the pesticide residues and ginsenoside content in different parts of ginseng had different distributions. Bacillus polymyxa had a significant effect on the degradation rate of pesticide residues in five parts and the content of 9 ginsenosides (P<0.05).
