摘要:

目的采用近红外光谱技术快速、无损检测山药药材中水浸出物、醇浸出物含量。方法采用近红外漫反射光谱建立定量校正模型。结果所建立的定量校正模型对水浸出物、醇浸出物的预测均方差RMSEP分别为1.26和0.084 9。结论近红外光谱技术不需要对样品进行复杂繁琐的前处理，分析速度快，结果准确，具有其他传统化学分析方法所不具有的显著优点，适合对组成复杂的中药进行快速分析，可用于中药生产过程的质量监控。

Abstract:

OBJECTIVE Rapid nondestructive determination of extracts by water and ethanol in Rhizoma Dioscoreae with near-infrared reflectance spectroscopy. METHODS Two quantitive models were built up with near-infrared diffuse reflectance spectroscopy. RESULTS The RMSEP in quantitative calibration model for extracts by water and ethanol were 1.26 and 0.084 9 respectively. CONCLUSION NIRS technique can dispose the samples without complicated pretreatment. You can achieve the results rapidly and correctly. It owns many remarkable advantages that cannot be displayed by traditional analysis methods. It is qualified to rapidly analyze traditional Chinese medicine(TCM) whose components are complex. NIRS can online control the quality in production process of TCM.
