| Abstract: | In the present paper the analysis of the total content of sugar in Chinese ginseng was carried out by using near infrared spectroscopy,and in combination with the PLS algorithm the calibration analysis was performed at the same time.The result shows that the precision obtained through common chemical methods is almost the same as the one through NIR spectroscopy.The SEC(standard error of calibration) is 1.9% and the correlation coefficient is 0.951 7,which proves that this technique is well suitable for rapid quantitative determination of the total content of sugar in Chinese ginseng,and is simple,cheap,and without any chemical pollution,and can present real time result. |
