0.5-10 95→ 75 5→25
10-15 75→ 45 25— 55
15-18 45→ 0 55—100

按照本发明的方法，通过对 100批参芪扶正注射液的总离子流图（ TIC ) 分析比较， 找出其共有特征峰， 用这些共有特征峰离子质量数提取得到提 取离子流图 （EIC ), 标出各共有特征峰的保留时间 Rt, 得到参芪扶正注射 液特征指纹图谱。
其共有特征峰为 18 个， 其保留时间 Rt 值及质量数分别为 7.1min ( 471.2083 )、 7.5min ( 491.1195 )、 8. lmin ( 441.1919 ), 8.6min ( 309.1555 )、

参芪扶正注射液质量标准中， 【指纹图谱】 项采用高效液相色谱 -紫外 检测法测定参芪扶正注射液的指纹图谱， 在一定程度上达到了监控其质量 的目的， 但其中占主要含量的皂苷类成分却在紫外基本无吸收； 【含量测 定】项采用香草醛-冰醋酸紫外分光光度法测定总皂苷含量， 采用高效液相 色谱 -蒸发光散射检测法测定黄芪甲苷含量，但仍不能全面反映皂苷类各成 分情况，在企业内控中，通过增加高效液相色谱 -蒸发光散射检测器检测指 纹图谱， 可以对皂苷类成分进行监控， 但需要增加样品前处理， 分析时间 也很长。
故本发明方法建立的参芪扶正注射液超高效液相色谱-四级杆飞行时 间质谱特征指纹图谱技术标准， 通过特征指纹图谱中共有峰的有无及特 征， 快速有效地全面监控药品质量， 保证质量的稳定、 均一、 可控。 本发 明还具有方法先进、 稳定性和重现性好等特点。 附图说明
