摘要:

摘要:目的:建立快速、准确、灵敏地测定D-木糖含量的高效液相色谱方法。方法:采用氨基柱分离,乙腈-水(73:27)为流动相,流速0.8mL/min,柱温30℃;NQAD漂移管温度50℃,载气为氮气,压力为30psi。结果:D-木糖的线性范围为10~120μg/mL(R2=0.9998),最低检出限为0.7μg/mL,平均加标回收率为101.97%,相对标准偏差(RSD)为0.88%。结论:该方法灵敏、准确、重复性好,适合于D-木糖的检测。

Abstract:

Abstract:Objective:To develop a fast, sensitive, accurate high-performance liquid chromatography(HPLC) with nano quantity analyte detector (NQAD) for the determination of D-xylose. Method: The chromatographic separation was achieved with an amino column using a mobile phase composed of a mixture of acetonitrile and water (73:27, V/V) at a flow rate of 0.8 mL/min. The NQAD drift tube temperature was set at 50℃ and the N2 pressure at 30psi. Result: The linear range of D-xylose was between 10μg/mL and 120μg/mL (R2=0.9998). The detection limit was 0.7μg/mL. The average spike recovery was 101.97%, with a relative standard deviation (RSD) of 0.88%. Conclution:This method is sensitive, accurate and repeatable, and thus it is suitable for the determination of D-xylose.
