摘要: 建立测定不同产地全缘叶绿绒蒿不同部位中总黄酮醇苷含量的方法。色谱条件为:Megres C18色谱柱(4.6 mm ×250 mm,5 μm),流动相采用甲醇-0.2%甲酸溶液(48∶52,V/V),洗脱时间40 min,检测波长为254 nm,流速为1.0 mL/min,柱温为40 ℃,进样量为5 μL。结果显示,槲皮素、山柰素和异鼠李素3种黄酮类化合物分别在0.7~70、0.7~70、0.4~40 μg/mL浓度范围内线性关系良好。本方法操作简便,精密度、稳定性和重复性良好,为进一步研究全缘叶绿绒蒿的质量检测和开发利用奠定了基础。

Abstract:

This study was conducted to establish a method to determine the content of total flavonol glycosides in different parts of Meconopsis integrifolia from different habitats.The mobile phase consisted of methanol-0.2% formic acid buffer (48∶52,V/V),with a flow rate of 1.0 mL/min,using Megres C18 column (4.6 mm ×250 mm,5 μm) with run time 40 min and UV detection at 254 nm.The column temperature was 40 ℃,and the injection volume was 5 μL.The results showed that the three flavonoids,quercetin,kaempferol and isorhamnetin,had good linear relationships in the concentration ranges of 0.7-70,0.7-70,and 0.4-40 μg/mL,respectively.The method is easy to operate,has good precision,stability and repeatability,and lays a foundation for further research on quality detection,development and utilization of M. integrifolia.

Key words: HPLC, Meconopsis integrifolia, total flavonol glycosides
