摘要:

目的:建立胡麻卵磷脂样品中磷脂酰胆碱的高效液相色谱分离分析方法。方法:采用Platisil C18色谱柱(150mm×4.6mm,5μm),检测波长为215nm,流动相为乙腈-甲醇(50:50,V/V),流速为1mL/min,以磷脂酰胆碱峰面积定量。结果:胡麻卵磷脂样品中磷脂酰胆碱的含量为73.6%,平均回收率为103.3%,精密度(RSD)为0.28%,检出限为0.25μg。结论:建立的方法准确、高效,结果真实可靠。

Abstract:

Objective: To establish an HPLC method for the separation and analysis of phosphatidylcholin in flax lecithin.
Methods: A Platisil C18 column (150 mm × 4.6 mm, 5 μm) was used for chromatographic separation using acetonitrilemethanol
(50:50, V:V) as mobile phase at flow rate of 1 mL/min. The detection wavelength was set at 215 nm. Results: The
content of phosphatidylcholin in flax lecithin was 73.6%, and the average spiked recovery rate was 103.3%. The precision
RSD for 6 replicate determinations was 0.28%, and the detection limit was 0.25 μg. Conclusion: The method is accurate,
efficient and can provide reliable results.
