ABSTRACT
Objective Near-infrared (NIR) spectroscopy was used as a fast analytical technique in the ethanol reflux-extraction process of red ginseng. Methods The NIR spectra of the extracting solution of red ginseng were obtained and the reference measurements of the active constituent in the extracting solution were performed by the colorimetric method. Firstly, the interference information in the spectra was detected by orthogonal signal correction (OSC) method. Then a calibration model between NIR spectra and reference measurements was established by partial least square regression. Results The results showed that the predictive accuracy of NIR calibration model used for the determination of ginsenoside in ethanol extracting process of red ginseng was good. Conclusion NIR Spectroscopy could be applied to the fast analysis for ethanol extracting processes of red ginseng.
