摘要

目的: 建立小白蒿中5种黄酮类化合物的同时测定方法

为综合评价小白蒿最佳采集时间提供参考依据。方法: 采用高效毛细管电泳法测定小白蒿中5种黄酮类化合物的含量

并对不同采集时间小白蒿和不同部位中5种黄酮类化合物的含量进行比较。结果: 在所用的实验操作条件下

5种对照品溶液分别在1.00~40.00 mg·L-1 (r= 0.999 8)

2.00~80.00 mg·L-1 (r= 0.999 9)

0.50~80.00 mg·L-1 (r= 0.999 6)

1.00~40.00 mg·L-1 (r= 0.999 3) 和1.00~40.00 mg·L-1 (r= 0.999 4)具有良好的线性关系

平均回收率分别为99.31% (RSD 1.60%)

98.14% (RSD 1.03%)

98.37% (RSD 1.57%)

97.92% (RSD 0.94%)

98.16% (RSD 1.20%)。结论: 实验结果表明

小白蒿花中黄酮类化合物的相对含量较高

最佳采集时间为6月中旬到7月末。

Abstract

Objective: To establish a method for determining five flavonoids in Artemisia frigida in order to review the collection time. Method: The content of five flavonoids in different collection time and parts of A. frigida was determined by HPCE and the content was compared to predicate the collection time. Result: The linear ranges of five flavonoids were 1.00-40.00 mg·L-1 (r=0.999 8)

2.00-80.00 mg·L-1 (r=0.999 9)

0.50-80.00 mg·L-1 (r=0.999 6)

1.00-40.00 mg·L-1 (r=0.999 3) and 1.00-40.00 mg·L-1 (r=0.999 4) respectively. The average recoveries of five flavonoids were 99.31% (RSD 1.60%)

98.14% (RSD 1.03%)

98.37% (RSD 1.57%)

97.92% (RSD 0.94%)

98.16% (RSD 1.20%). Conclusion: The content of five flavonoids in the flower is more than that in other parts. The optimal collection time is from the middle of June to the end of July.
