摘要
目的:测定马来酰肼(MH)残留量,并探讨其对白术质量的影响。方法:白术现蕾期,施用不同浓度MH水剂,采收期测定白术MH残留及糖类、内酯类成分的含量,并采用独立样本t检验和主成分分析法评价MH对白术内在质量的影响。结果:白术根茎MH残留量为0.3~2.2 mg/kg;独立样本t检验显示内酯类成分的含量随MH施用浓度升高呈低-高-低趋势;主成分分析显示,施用MH对白术内在质量具有显著影响,75和100倍液时白术质量综合评价指数最高。结论:保证低残留的同时,施用适当浓度的MH可以提高白术产量及内在质量。
Abstract Objective ：To determine maleie hydrazide（MH） residues and discuss its influence on the quality of Atractylodes macro- cephala. Methods ： At the bud stage, A. rru^rocephala different concentration of MH. Then MH residues, the contents of sugar and lae- tone were determined by HPLC and UV. The quality of A. macrocephala was comprehensively evaluated by independent sample t test and principal component analysis. Results ： 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 laetone 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. Conclusion：Proper concentration MH is applied to ensure low concen- tration MH residues and improve yield and quality of A. macrocephala.
