我国不同产地红花的质量分析

Quality analysis of safflower in different regions of China

目的运用多指标、多成分定量方法,对不同产地的红花进行质量分析。方法按照《中国药典》（2010年版）一部红花＂检查＂项下杂质、水分、灰份和酸不溶性灰份、吸光度、浸出物、羟基红花黄色素A的检测方法检测。结果 23批不同产地红花的杂质含量为0.2%-1.8%,水分含量为5.6%-8.68%,总灰分含量为4.69%-22.21%,酸不溶性灰分含量为1.08%-14.56%,红色素吸光度2.090-0.529 4,浸出物含量为35.50%-43.10%,羟基红花黄色素A的含量1.08%-2.32%。结论对红花样品进行聚类分析,结果表明当样本层次聚类分析聚成2类时：新疆和田红花为一类,为不合格药材;其余产地的红花为一类均为合格药材;其中合格药材中新疆的昌吉、伊犁、塔城地区的样品聚为一类,四川和云南地区的样品聚为一类。说明产地对红花质量的综合评价具有一定的影响。

Objective To analyzed the quality of safflower in different regions by the method of multi-index and multicomponent quantitative. Methods The detection method was on the basis of impurities,water,ash,acid insoluble ash,absorbance,extract,and Hydroxysafflor yellow A under safflower ‘check＇entry in Chinese pharmacopoeia（ 2010edition）. Results In the 23 batches of safflower produced in different regions,impurity content was 0. 2% - 1. 8%,moisture content was 5. 6 - 8. 68%,total ash content was 4. 69% - 22. 21%,insoluble ash content was 1. 08% - 14.56%,pigment absorbance was 2. 090 - 0. 529 4,extract content was 35. 50% - 43. 10%,and the content of Hydroxysafflor yellow A was 1. 08% - 2. 32%. Conclusion Cluster analysis was performed on safflower samples,and the results showed that when hierarchical cluster analysis was clustered into two classes,safflower of Hetian of Xinjiang province was one class belonged to substandard medicines,safflowers of other areas were one class belonged to all qualified medicines. Of the qualified medicines,samples of Changji,Yili,Tacheng of Xinjiang clustered into one class,the sample of Sichuan and Yunnan regions clustered into one class,indicating that producing areas had certain impact on comprehensive evaluation of the quality of safflower.
