  • 简介:Xingxiong注射(XXI)是叶片白果树摘录和ligustrazine为心血管、脑血管的疾病的治疗作好准备的一个广泛地使用的中国草药的公式。与药理学研究相比,这个公式上的化学分析和质量控制研究是相对有限的。在现在的学习,高效液体层析结合了四极time-of-flight团spectrometry(HPLC-QTOFMS)方法在XXI被用于成分的全面分析。根据破碎规则和以前的报告,三十白果树flavonoids,四白果树萜烯内酯,和一碱被识别。高效液体层析结合了三倍的四极团spectrometry(HPLC-QQQMS)方法然后被使用确定在XXI的十主要成分。方法确认结果显示发达方法有理想的特性,线性,精确和精确性。白果树flavonoids的全部的内容关于22.05-25.51g·mL−1,白果树萜烯内酯数量分别地关于在XXI样品的六批的4.41-8.70g·mL−1。而且,余弦比率算法和距离大小被采用评估XXI样品的类似,并且结果表明了高质量的一致性。这个工作能在Xingxiong注射的质量控制上提供全面信息,它在一个合理质量控制标准的建立是有用的。
