摘要

目的：测定不同生长年限与采收时间玉竹药材中主要活性成分的含量，探索其动态变化规律，为确定玉竹最佳采收期，控制玉竹质量提供指导。方法：采用紫外-可见分光光度法测定不同生长年限与采收时间玉竹药材中多糖类、黄酮类、皂苷类，醇浸出物的含量，运用多重方差分析对实验结果进行统计分析。结果：玉竹主要活性成分含量在采收时间内的变化规律为前期增长较慢，中期增长较快，后期增幅变缓，且在9月底之后各成分含量基本上都趋于平稳，此时玉竹中多糖、皂苷、黄酮、醇浸出物的质量分数分别为7.69%，0.453%，0.141%，57.48%。玉竹中多糖、皂苷、黄酮、醇浸出物的质量分数并没有随着生长年限的增加而持续高速增加，3年即达到峰值，质量分数分别为7.67%，0.436%，0.141%，55.59%。结论：玉竹主要活性成分随玉竹的生长发育不断累积，但含量并非都保持高速增长状态。最佳采收年限为3年生，最佳采收期为9月底，动态变化规律的研究可为提高玉竹药材质量提供参考依据。

Abstract

Objective: To provide guidance for determining the optimal harvesting time

and controling the quality of Polygonati Odorati Rhizoma by measuring the contents of main active ingredients in Polygonati Odorati Rhizoma from different growing ages and harvesting time

and exploring their dynamic variation rule. Method: UV-visible spectrophotometry was used to measure the contents of polysaccharides

flavonoids

saponins

alcohol-soluble extracts in Polygonati Odorati Rhizoma from different growing ages and harvesting time

multiple analysis of variance was used to analyze the experimental results. Result: The variation rule of the contents of main active ingredients in Polygonati Odorati Rhizoma in harvesting time was slow at the early growth

faster at medium-term

slow down at the late growth

and the contents of every ingredients changed to be steady after the end of September

the contents of polysaccharides

saponins

flavonoids

alcohol-soluble extracts in Polygonati Odorati Rhizoma were 7.69%

0.453%

0.141%

57.48% at this stage.The contents of polysaccharides

saponins

flavonoids

alcohol-soluble extracts in Polygonati Odorati Rhizoma didn't sustained increase rapidly with the increase of growing years

and reached the peak after 3 years growth

the contents were 7.67%

0.436%

0.141%

55.59%. Conclusion: The main active ingredients were constantly accumulated with plant growth

but its content did not always maintain a high growth state. The optimal harvest year was 3-year-old

the optimal harvest time was the end of September

the study of dynamic variation rule could provide certain reference basis for improving the medical quality of Polygonati Odorati Rhizoma.
