摘要:

目的利用近红外光谱技术，快速测定丹参药材中丹参酮ⅡA的含量。方法运用偏最小二乘法(PLS)建立丹参药材中丹参酮ⅡA含量与其近红外光谱之间的校正模型，并对未知的丹参样品进行丹参酮ⅡA含量预测。结果校正集内部交叉验证决定系数R²为0.996 94，交互验证均方根偏差RMSECV为0.011 8，11份样品的外部预测均方根偏差RMSEP为0.023 7。预测值的平均相对误差为1.712 9%。结论近红外光谱技术测定丹参药材中丹参酮ⅡA的含量是可行的，该方法快速准确、简单无损，可应用于大批量样品的快速分析。

Abstract:

OBJECTIVE To rapidly determine the content of tanshinoneⅡA in Salvia miltiorrhiza extraction by near-infrared spectroscopy. METHODS The calibration model of the content of tanshinoneⅡA in Salvia miltiorrhiza and the near infrared spectroscopy of Salvia miltiorrhiza was built with partial least squares. RESULTS The correlation coefficient of calibration (R²) was 0.996 94. Root mean square error of cross validation (RMSECV) was 0.011 8, and external prediction deviation RMSEP of 11 samples was 0.023 7. Predicted average relative error was 1.712 9%. CONCLUSION It is feasible to determine the tanshinoneⅡA content in Salvia miltiorrh. Near-infrared spectroscopy is fast, accurate, simple and nondestructive which can be applied in rapid analysis of large numbers of samples.
