中文摘要:目的:建立多波长切换HPLC同时测定车前草中大车前苷、毛蕊花糖苷、异毛蕊花糖苷、木犀草素和芹菜素5个活性成分的含量测定方法。方法:采用Waters Symmetry C18 色谱柱(250 mm×4.6 mm,5 μm),以乙腈(A)-0.1%甲酸水(B)溶液为流动相,梯度洗脱,检测波长为330 nm(0~29 min检测大车前苷、毛蕊花糖苷和异毛蕊花糖苷)、350 nm(29.01~31 min检测木犀草素)和338 nm(31.01~35 min检测芹菜素),流速为0.8 mL·min-1,柱温为25 ℃。结果:在所建立的色谱条件下各成分的专属性良好,无干扰峰;大车前苷、毛蕊花糖苷、异毛蕊花糖苷、木犀草素和芹菜素的线性范围分别为42.84~428.40 μg·mL-1(r=0.999 7)、35.36~353.60 μg·mL-1(r=0.999 5) 、18.40~184.00 μg·mL-1(r=0.999 5)、0.856~8.56 μg·mL-1(r=0.999 6)和0.108~1.08 μg·mL-1(r=0.999 6);平均回收率(n=6)分别为98.62%(RSD=0.87%)、98.09%(RSD=1.10%)、98.19%(RSD=1.16%)、95.52%(RSD=1.03%)、92.34%(2.00%);6批车前草样品中5种成分的含量范围分别为1.51~6.78、2.53~18.77、0.60~2.92、0.03~0.18、5.34~12.36 μg·g-1。结论:该方法操作简单、准确、灵敏度高、重复性好,为车前草的质量控制提供参考依据。 |

Abstract:Objective:To establish a method for simultaneous determination of plantamajoside,acteoside,isoacteoside,luteolin and apigenin in Plantaginis herba by HPLC with wavelength switching.Methods:The samples were separated on a Waters Symmetry C18 column(250 mm×4.6 mm,5 μm)by a gradient elution using acetonitrile(A)and 0.1% formic acid(B)as mobile phase.The detection wavelength was set at 330 nm(0-29 min,for plantamajoside,acteoside,isoacteoside),at 350 nm(29.01-31 min,for luteolin),at 338 nm(31.01-35 min,for apigenin).The flow rate was 0.8 mL·min-1and the column temperature was 25 ℃.Results:The specificity of the established method was good,and there was no interference peaks.The linear ranges of plantamajoside,acteoside,isoacteoside,luteolin and apigenin were 42.84-428.40 μg·mL-1(r=0.999 7),35.36-353.60 μg·mL-1(r=0.999 5),18.40-184.00 μg·mL-1(r=0.999 5),0.856-8.56 μg·mL-1(r=0.999 6)and 0.108-1.08 μg·mL-1(r=0.999 6),respectively.The average recoveries(n=6)were 98.62%(RSD=0.87%),98.09%(RSD=1.10%),98.19%(RSD=1.16%),95.52%(RSD=1.03%)and 92.34%(RSD=2.00%),respectively.The contents of five components in 6 batches for samples were 1.51-6.78,2.53-18.77,0.60-2.92,0.03-0.18 mg·g-1 and 5.34-12.36 μg·g-1,respectively.Conclusion:The established method is simple,accurate,high sensitive and well reproducible,which could provide a theoretical basis for the quality control of Plantaginis herba. |
