摘　　要：目的:近红外技术快速无损检测丹参药材中丹酚酸B与丹参酮ⅡA含量的实验方法。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丹酚酸B与丹参酮ⅡA的预测均方差(RMSEP)分别为0.259和0.0232。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,具有其它传统化学分析方法所不具有的显著优点,很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。Objective ： Rapid nondestructive determination of salvianolic acid B and tanshinone Ⅱ A in Radix Salviae Miltiorrhizae with near-infrared reflectance spectroscopy. Method： A quantitive model was built up with near-infrared diffuse reflectance spectroscopy. Results ： The RMSEP in quantitative calibration model for salvianolic acid B and tanshinone Ⅱ A were 0. 259 and 0. 0232 respectively. Conclusion： NIR 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 whose components are complex. NIR can control the quality in production process of traditional Chinese medicine.
