〔Abstract〕 Objective To identify the main active ingredients quickly in Reduning injection by high performance liquid chromatography quadrupole time of flight tandem mass spectrometry (HPLC-Q-TOF-MS) technology, and to clarify the material basis and trace components of Reduning injection. Methods The HPLC-Q-TOF-MS technique was first employed to investigation the fragmentation pathways of chlorogenic acids and polyphenols. And then, the structures of the main active ingredients in Reduning injection were speculated using the well-investigated fragmentation pathways of standards combined with the literatures. Results A total of 40 compounds, which including 14 chlorogenic acid, 13 iridoid, and 13 organic acid type compounds were identified from Reduning injection. Among them, 24 compounds were reported for the first time in Reduning injection. Conclusion The chlorogenic acids, iridoids and organic acid compounds were the main active ingredients of Reduning injection.

热毒宁注射液是由青蒿、金银花、栀子三味中药材组方制成的复方制剂,1 mL热毒宁注射液由1.25 g青蒿、0.75 g金银花和0.6 g栀子提取加工而成[1-2]。热毒宁注射液具有清热、疏风、解毒之功效,临床上主要用于外感风热所引起的高热畏寒、头身疼痛、咳嗽咳痰等上呼吸道感染[3-4]。热毒宁注射液的主要活性成分为有机酚酸类和环烯醚萜类,包括绿原酸、隐绿原酸、异绿原酸A、异绿原酸B、栀子苷、京尼平苷酸、京尼平龙胆双糖苷等[5-6],除了这些主要的活性成分,热毒宁注射液中还存在一系列含量较低的化学成分,这些化学成分需要进一步研究。
在2020年第七版《新型冠状病毒肺炎诊疗方案》[7]中,热毒宁注射液被推荐用于新型冠状病毒肺炎的治疗。同时,其被列入《甲型H1N1流感诊疗方案》《登革热诊疗指南》《人感染H7N9禽流感\疗方案》中[8-10]。但是,在临床使用热毒宁注射液的过程中,出现了多种不良反应,主要表现为过敏、皮肤损伤,严重时出现过敏性休克[11-12]。热毒宁注射液除了主要活性成分,还有很多低含量的化合物没有被报道,而这些物质可能导致热毒宁注射液出现不良反应。因此,本文拟采用高灵敏度的质谱技术对热毒宁注射液中化学成分进行系统研究不仅有利于其质量控制,而且可对过敏原的筛查奠定物质基础。
