摘 要:目的建立高效液相色谱法同时测定更年灵胶囊中淫羊藿苷、维生素B1及维生素B6的含量。方法采用高效液相方法,色谱柱:Ultimate AQ-C(18)(4.6 mm×250 mm,5μm);流动相:0.04%庚烷磺酸钠溶液(含0.12%的三乙胺,用冰醋酸调节pH值至3.3)(A)-乙腈(B)梯度洗脱;检测波长:270 nm;柱温:20℃;流速:1.0 mL/min。结果淫羊藿苷、维生素B1和维生素B6分别在4.052~48.624、21.63~255.12和20.50~246.00μg/mL范围内,与其峰面积呈良好的线性关系(r=0.999 8、1.000、1.000,n=6)。平均回收率(n=6)分别为99.37%(RSD=1.08%)、100.93%(RSD=1.70%)和99.34%(RSD=1.76%)。结论该法操作简便,结果准确、重复性好,可用于更年灵胶囊的质量控制。Objective To establish a method for simultaneous determination of icariin,vitamin B1 and vitamin B6 in gengnianling capsule by HPLC.Methods The HPLC with Ultimate AQ-C(18)(250 mm × 4.6 mm,5 μm) column was used,mobile phase was heptanesulfonic acid sodium salt solution(A)-acetonitrile(B) gradient elution,the detection wavelength was at 270 nm;The column temperature was 20℃ with the flow rate of 1.0 mL/min.Results The linear range of icariin,vitamin B1 and vitamin B6 was 4.052 ~ 48.624 μg/mL(r = 0.999 8),21.63 ~255.12 μg/mL(r= 1.000) and 20.50 ~246.00 μg/mL(r = 1.000),the recovery rates were 99.37%(RSD =1.08%),100.93%(RSD = 1.70%) and 99.34%(RSD = 1.76%).Conclusion The method is simple and accurate with good reproducibility,and it can be used for the quality control of gengnianling capsule.
