【摘要】：目的:建立同时测定舒肝宁注射液中5种成分含量的方法。方法:采用高效液相色谱法。色谱柱为Symmetry~? C_(18),流动相为甲醇-0.4%磷酸溶液(梯度洗脱),流速为1.0 mL/min,检测波长为238 nm(栀子苷、黄芩苷)、327 nm(绿原酸、野黄芩苷、黄芩素),柱温为30℃,进样量为10μL。结果:绿原酸、栀子苷、黄芩苷、黄芩素、野黄芩苷检测质量浓度线性范围分别为0.406 2~26.0μg/mL(r=0.999 9)、2.500 0~160.0μg/mL(r=0.999 9)、6.562 0~420.0μg/mL(r=0.999 9)、0.312 5~20.0μg/mL(r=0.9996)、0.585 9~37.5μg/mL(r=0.999 8);定量限≤31.20 ng,检测限≤15.60 ng;精密度、稳定性、重复性试验的RSD2.0%;加样回收率分别为97.72%~101.10%(RSD=1.21%,n=6)、97.67%~102.40%(RSD=1.87%,n=6)、97.64%~101.10%(RSD=1.31%,n=6)、96.45%~100.10%(RSD=1.47%,n=6)、96.16%~101.10%(RSD=1.69%,n=6)。结论:该方法操作简便,精密度、稳定性、重复性好,可用于舒肝宁注射液中5种成分含量的同时测定。
