首次利用近红外漫反射技术和偏最小二乘法定量分析了复方芦丁片的主组分芦丁和维生素C混合样品的含量 ,所建立的预测方程对样品的预测值和真实值之间的相关系数为 99 75 %,芦丁和维生素C定标标准差分别为 0 3 63 %和 1 0 78%。该方法快速、准确、不破坏样品
For the first time, the content of rutin and vitamin C in compound rutin tablets was quantitatively analyzed by near-infrared diffuse reflectance spectroscopy and partial least squares. The correlation between the predicted value and the true value of the established prediction equation The coefficient was 99 75%, and the standard deviation of calibration for rutin and vitamin C was 0 3 63% and 1 0 78%, respectively. The method is fast, accurate and does not damage the sample
