摘要

目的建立中药材群体指纹图谱信息量及一次投料量数学模型并进行实验验证。方法运用信息熵及遗传统计学原理,建立数学模型,以大黄醇提物及鱼腥草挥发油进行验证。结果建立了中药群体指纹图谱信息量及制剂稳态质量控制的一次投料量数学模型。大黄醇提物采用HPLC测定,在4.189μg进样量时指纹图谱的绝对和相对信息量较大,指纹图谱绝对信息量为1.535×109μV.s,RSD为37.23%,相对信息量为5.360×108μV.s.μg-1,RSD为19.42%;稳态质量控制一次投料量共需80 836 g。鱼腥草挥发油采用GC测定,指纹图谱的绝对信息量为2.472×107 mV.s,RSD为90.46%,相对信息...
