摘 要:目的:应用超高效液相色谱-蒸发光散射(UPLC-ELSD)检测柴胡中柴胡皂苷a、d的含量。方法:采用Waters Acquity UPLC BEH C18色谱柱(2.1 mm×100 mm,1.7μm);以乙腈(A)-水(B)为流动相梯度洗脱(0~3 min,43%A;3~9 min,43%A→63%A);流速:0.2 mL·min-1;柱温:30℃;ELSD检测器漂移管温度为40℃,气体压力为40 psi,测定柴胡中柴胡皂苷a、d的含量。结果:柴胡中柴胡皂苷a在浓度为64.2~385.2μg·mL-1(r=0.9994)内线性范围良好;柴胡皂苷d在浓度为67.3~403.8μg·mL-1(r=0.9992)内线性范围良好。结论:该方法简便、灵敏、可靠、准确、重现性好,可作为柴胡的质量控制方法。Objective: To determine saikosaponin a, d in Radix Bupleuri by SPE-HPLC-ELSD. Methods: The amounts of saikosaponin a, d in Radix Bupleuri were determined by SPE-UPLC-ELSD with a Waters Acquity UPLC BEH C18 column (2.1 mm×100mm,1.7μm) kept at 30℃, gradient mobile phase of acetonitrile (A)-water (B) [0-3 rain, 43% A; 3-9 rain, 43% A-63% A] at a flow rate of 0.2 mL.min-L The tube temperature of the detector was 40℃. The press of pure air was 40 psi. Result: The linear ranges for saikosaponin a and d were 64.2-385.2 μg·mL-1 (r=0.9994) and 67.3-403.8 μg·mL-1 (r=0.9992), respectively. Conclusion: This method is easy, sensitive, reliable, accurate, reproducible and can be used as the quality control method of Radix Bupleuri.
