| 摘 要： | 目的：通过对高效液相色谱法(HPLC)及紫外可见分光光度法测定例柏叶黄酮进行比较,寻找一种较准确、简单的测定侧柏叶黄酮的方法。方法：HPLC法：流动相由乙睛：0．01mol/L KH2PO4：乙酸(28：72：1．5,V／V)组成;流速1．0mL.min^-1;检测波长为260nm,以槲皮甙为参照品。紫外／可见分光光度法：以芦丁为参照品,410nm波长测定黄酮含量。结果：两种方法都有较好的精密度．但测定的结果有较大差异．紫外／可见分光光度法测得的结果比HPLC法高。结论：以槲皮甙为定量指标更能准确地反映侧柏叶的内在质量,HPLC法是一种较理想的测定方法。

| Abstract: | Objective:To find a simple method for the detection of anthoxanthin in leaves of Platychadus orientalis. Methods:Anthoxanthin content was determined by HPLC(velocity:1.0 mL/min;wavelength,260 nm)and UV VIS spectrophotometry(wavelength:410 nm),respectively.The contrast samples were quercitrin for HPLC and rutin for UV VIS spectrophotometry.Results:Both methods had high measurement precision,but the measurement result in UV VIS spectrophotometry was about 3 times that in HPLC.Conclusion:Quercitrin as a quantitative indication can precisely reflect anthoxanthin quality.HPLC may be an ideal method for detection of anthoxanthin in leaves of Platychadus orientalis. |
