Objective To find out the effect factors of uncertainty by analyzing the uncertainty of measurement in determination of catalpinoside by HPLC and provide the evidence to evaluate the measurement. Methods The Catalpinoside in Ganmainingxin Capsules was determined by HPLC. The causes and effects were simplified and uncertainty was appraised. Results The uncertainty result was 2.70% and the result of content was(1.17±0.063)mg/g. Conclusions The mathematic model established is suitable for uncertainty analysis of catalpinoside by HPLC.
