HPLC测定补肾口服液中淫羊藿苷的不确定度分析

Analysis of Uncertainty for Determination of the Icariin in Bushen Oral Liquid by HPLC

目的:建立HPLC测定补肾口服液中淫羊藿苷的不确定度评价方法。方法:采用HPLC法测定补肾口服液中淫羊藿苷含量,分析影响其不确定度的因素来源,对各个不确定度因素进行评定,并计算合成不确定度,最终给出测量结果的扩展不确定度和置信水平。结果:本次试验补肾口服液中淫羊藿苷含量测定结果为(0.221 2±0.014 0)g·L-1。结论:建立的不确定度评定法适用于HPLC法测定补肾口服液中淫羊藿苷含量的不确定度分析。

Objective： To establish a HPLC method for uncertainty analysis of icariin in bushen oral liquid. Method： HPLC method was established to determinate the content of icariin. Each active component of uncertainty was calculated the variable parameters among the procedures. The combined uncertainty and extended uncertainty and confidence were finally obtained by synthesized the uncertainties of various component variables. Result： The determined content of icariin in bushen oral liquid of this test is （0. 221 2± 0.014 0） g.L^-1. Conclusion： The established mathematic model is applicable to the uncertainty analysis of icariin in bushen oral liquid by HPLC method.
