摘要: 目的:建立检测石榴籽中鞣花酸的含量测定方法。方法:采用反相高效液相色谱法,Arcus EP-C18(250mm×4.6mm,5μm)色谱柱,以甲醇-0.1% TFA溶液为流动相梯度洗脱,流速1.0mL/min,检测波长254nm。结果:鞣花酸0.004~0.064μg之间线性关系良好,平均加样回收率为100.49%。结论:本方法精密可靠,可作为检测石榴籽中鞣花酸含量的方法。

Abstract: Objective: To establish an HPLC method for the determination of ellagic acid in pomegranate seeds. Methods: The chromatographic separation was carried out on an Arcus EP-C18 column (250 mm × 4.6 mm, 5 μm) using a mobile phase composed of a mixture of methanol and 0.1% TFA at a flow rate of 1.0 mL/min by gradient elution. The detection wavelength was 254 nm. Results: The linear range was 0.004-0.064 μg for ellagic acid. The average recovery rate was 100.49%. Conclusion: This method is accurate, reproducible and applicable for quality control of ellagic acid in pomegranate seeds.

Key words: pomegranate seedsl, ellagic acid, RP-HPLC
