ABSTRACT
Objective:
To establish a rapid analysis method for determining the content of ephedrine in Biyan sprays.Methods:
The FT-NIR spectra of the samples were collected by near-infrared liquid transmission spectroscopy. Using the HPLC analysis values as the reference, a quantitative analysis model for ephedrine was established with partial least square ( PLS) , the first derivative and Nor-ris smooth was used in the spectra pretreatment, and 6 136. 38-5 364. 99 cm-1 and 7 038. 90-6 969. 48 cm-1 were selected as the fre-quency ranges.Results:
R2 and RMSEC of the calibration set was 0. 992 6 and 1. 20, respectively. R2 and RMSEP of the vallidation set was 0. 993 5 and 1. 28, respectively. R2 and RMSEP of the cross validation set was 0. 986 9 and 1. 60, respectively.Conclusion:
The method is rapid and non-desturctive, and can be applied in the rapid assessment and online examination of the quality of Biyan sprays.
