红外光谱法建模快速筛查抗风湿类中成药中的乙酰水杨酸

Rapid Screening of Acetylsalicylic Acid in Anti-rheumatic Chinese Medicines by FT-IR Model

对抗风湿类中成药中添加乙酰水杨酸的快速筛查方法进行了研究。以13种市售抗风湿类中成药为研究对象,采集研究样品的红外光谱图（FT-IR）,采用判别分析法（Discriminant Analysis）建立了抗风湿类中成药中乙酰水杨酸的快速筛查模型。用此模型检测了另外17种市售抗风湿类中成药,结果表明,阴性样品和阳性样品的识别正确率为100%,误判数为0。

The method of rapid screening of acetylsalicylic acid in anti-rheumatic Chinese medicines was investigated. Taking 13 kinds of anti-rheumatic Chinese medicines as the objects,the recognition model of acetylsalicylic acid was established using FT-IR combined with discriminant analysis.The model was used to detect other 17 samples,and the results showed that the correct recognition rate of model was 100%,and the miscarriage of justice was 0.
