To determine maleic hydrazide (MH) residues and discuss its influence on the quality of Atractylodes macrocephala.
At the bud stage, A. macrocephala different concentration of MH. Then MH residues,the contents of sugar and lactone were determined by HPLC and UV. The quality of A. macrocephala was comprehensively evaluated by independent sample t test and principal component analysis.
The range of MH residues was 0.3-2.2 mg/kg. The results of independent sample t test revealed that the trend of the contents of lactone was low-high-low with the increase of MH, and the effect of MH on the content of sugar was barely obvious. Meanwhile, principal component analysis showed that comprehensive evaluation on the quality of A. macrocephala was the best when MH with 75 or 100 times water was applied.
Proper concentration MH is applied to ensure low concentration MH residues and improve yield and quality of A. macrocephala.
测定马来酰肼（MH）残留量，并探讨其对白术质量的影响。
在白术芽期，喷施不同浓度的MH。然后采用高效液相色谱法（HPLC）和紫外分光光度法（UV）测定MH残留量、糖分和内酯含量。通过独立样本t检验和主成分分析对白术质量进行综合评价。
MH残留量范围为0.3 - 2.2 mg/kg。独立样本t检验结果显示，随着MH浓度增加，内酯含量呈低-高-低趋势，而MH对糖分含量的影响不明显。同时，主成分分析表明，喷施75倍水或100倍水的MH时，对白术质量的综合评价最佳。
施用适当浓度的MH可确保低浓度的MH残留，并提高白术的产量和质量。
