Abstract
采用高效液相色谱法测定针叶樱桃提取物中VB1和VB2的含量,优化样品制备方法及HPLC色谱条件,并将该方法用于针叶樱桃提取物中VB1和VB2的含量测定.方法:采用HPLC法,色谱柱Diamonsil C18柱(250mm ×4.6mm,5μm),柱温为40℃,进样体积20μL,流速1.0mL/min,检测波长280nm,流动相组成为乙腈和5mol/L庚烷磺酸钠溶液,采用梯度洗脱模式.方法学考察表明,VB1和VB2分别在0.089 μg/mL-0.89 μg/mL和0.086μg/mL-0.86μg/mL范围内线性关系良好,方法的精密度和重复性均符合要求,平均回收率为99.5%~101.1%.该方法操作简单,能够用于针叶樱桃提取物中VB1和VB2的含量测定.
