摘　　要：目的:高效液相色谱法测定湿米粉中米酵菌酸和毒黄素含量的不确定度。方法:通过建立数学模型,分析测定过程中的不确定度来源。结果:毒黄素的测定结果为(7.17±0.24) μg·mL^(-1),米酵菌酸的测定结果为(7.10±0.25) μg·mL^(-1)。结论:该方法主要不确定来源为标准溶液配制过程和样品定容体积,提示样品检测过程中需对这两个方面进行严格控制,以提高检测数据的准确性。Objective:To determine the uncertainty of rice yeast acid and toxoflavin in wet rice flour by HPLC.Method:The source of uncertainty was analyzed by establishing mathematical model.Result:The results of toxoflavin and rice yeast were (7.17±0.24) μg·mL~(-1) and (7.10±0.25) μg·mL~(-1) respectively.Conclusion:The main source of uncertainty in this method are the standard solution preparation process and the constant volume of the sample,which suggests that these two aspects should be strictly controlled in the process of sample detection to improve the accuracy of detection data.
