摘要:本文运用了统计矩原理阐明并建立中药复方多成分指纹图谱定性定量分析法:总量统计矩方法。包括4个参数:①总零阶矩AUC,;②总响应率AUCPW,;③总量一阶矩MCRT,,亦总量中心矩或总量平均保留时间,用
五,表示;④总体二阶矩VCRT,,亦为平均保留时间方差,用12表示。AUC,能用于中药复方指纹图谱定量分析,
AUCPWT、MCRT,JCRT,能用于中药复方指纹图谱定性分析。以此法研究不同产地大黄醇浸膏成分HPLC指纹图谱,得总量统计矩参数:AUCT为3.273×10。trV s;AUCPWT为2.286×106pV s nag~;MCRTT为33.50
min;
VCRT,为484.4nain2;浓度C,为143.2mg naL-’。本法具有加合运算的特征,能消除溶剂干扰,获得纯品的总量统
计矩参数;具偶联性,能与多维向量偶联构成多维曲线中心矩及偏差分析。
