|
摘要
目的建立疏血通注射液中游离氨基酸的UPLC指纹图谱分析方法。方法采用异硫氰酸苯酯(PITC)衍生化方法,使用Waters Acquity超高效液相色谱仪,以CORTECS?C18柱(150 mm×2.1 mm,1.6μm),乙腈-0.1%甲酸水进行梯度洗脱,体积流量为0.1 mL/min,柱温为25℃,进样量为2μL,检测波长为254 nm。结果 33批不同批次疏血通注射液中有28个共有峰,其中有15个已知峰,分别为组氨酸(His)、精氨酸(Arg)、丝氨酸(Ser)、甘氨酸(Gly)、谷氨酸(Glu)、天冬氨酸(Asp)、苏氨酸(Thr)、脯氨酸(Pro)、丙氨酸(Ala)、酪氨酸(Tyr)、甲硫氨酸(Met)、缬氨酸(Val)、亮氨酸(Leu)、赖氨酸(Lys)、苯丙氨酸(Phe),不同批次的样品与标准指纹图谱相似度均在0.994以上。结论本实验建立的UPLC指纹图谱分析方法稳定、精密度高,可应用于疏血通注射液的质量控制和评价。
