| 摘 要： | 采用近红外光谱分析技术对人参进行了光谱及定量分析。对人参的原始漫反射吸收光谱采用二阶导数、散射校正、相关分析等多种光谱解析手段，研究了人参中的主要成分总皂甙的光谱吸收特性，并结合偏最小二乘回归法对人参总皂甙进行了定标建模分析。分析结果精度高，定标标准差(RMSEC)为0.154％，相关系数为0.982 8。

| Abstract: | In the present paper the saponin in Chinese ginseng was analysed quantitatively by using near infrared spectroscopy.The spectral characteristics of the primary ingredients in Chinese ginseng were obtained by applying second derivative,MSC(Multiple Scatter Correction),and correlation chart to the original absorbance spectra of ginseng.Meantime,in combination with the PLS algorithm the calibration process was performed for the quantitative analysis of saponin in Chinese ginseng.The result obtained shows a fine precision of the method,with RMSEC of 0.154% and correlation coefficient of 0.982 8. |
