摘要:
建立高效液相指纹图谱进行外部质量控制,结合化学计量学探究内部质量影响因素,通过量值传递规律确定制备工艺稳定性,全面完善薏苡竹叶散(YZP)质量评价系统。利用《中药色谱指纹图谱相似度评价系统》(2012.130723版本)绘制15批YZP指纹图谱并评价相似度; 选择Origin 2019b 64Bit进行聚类分析(CA),利用SIMCA 14.1进行主成分分析(PCA)和正交偏最小二乘判别分析(OPLS-DA),获得导致质量差异的主要成分; 测定15批淡竹叶药材和YZP中荭草苷和异荭草苷的含量,探究样品制备过程中的量值传递规律。结果表明,15批YZP指纹图谱得到21个共有峰,指认了6种成分,分别为9号峰(异荭草苷)、10号峰(荭草苷)、13号峰(牡荆素)、14号峰(异牡荆素)、15号峰(连翘酯苷A)和20号峰(连翘苷),相似度在0.956~0.995之间,符合相关规定; CA结果显示,15批YZP被分为两类,PCA共得到3个主成分,累计贡献率82.4%,OPLS-DA得出10个贡献率较大成分,包括已指认出的9号峰(异荭草苷)、13号峰(牡荆素)和20号峰(连翘苷),有利于进一步质量评价; 15批淡竹叶饮片中荭草苷、异荭草苷的质量分数为0.2156%~0.9923%、0.530%~2.052%,15批YZP中荭草苷、异荭草苷的质量分数为0.022%~0.112%、0.065%~0.312%,饮片-YZP中荭草苷、异荭草苷转移率为78.41%~119.54%、74.57%~127.96%,转移率皆在平均值±30%范围内,未出现离散值,说明制备工艺较稳定。本文建立了HPLC指纹图谱结合多指标含量测定方法,有效控制YZP外部质量,通过化学计量学确定了影响质量的内部因素,转移率稳定确定制备工艺稳定可靠,为YZP全面质量评价奠定基础。
