[Abstract]
Objective Through detecting the three components, strychnine, brucine, and ephedrine in Yaotongning Capsule by using near-infrared (NIR) spectroscopy to establish a rapid detection method in production process of Yaotongning Capsule. Methods Powder form the different batches of Yaotongning Capsule was collected and examined by NIR spectroscopy. The main components in Yaotongning Capsule were detected through the correct model via a partial least squares (PLS) established and NIR spectroscopy. Results There was a good linear relationship between NIR data and the contents of strychnine, brucine, and ephedrine in the samples. The correlation coefficients were 0.924, 0.944, and 0.874, and root-mean-square error of prediction (RMSEP) were 0.03, 0.06, and 0.02, respectively. Conclusion This method could be used to effectively determine strychnine, brucine, and ephedrine in Yaotongning Capsule, and thus guide the quality control in productive process
