Abstract:
Objective To determine ecdysterone content in Radix Achyranthis Bidentalae by near-infrared diffuse reflectance spectroscopy (NIRDRS) combined with partial least squares (PLS). Methods NIRDRS and PLS. Results The correlation coefficient of the quantitative mathematics model between the prediction and the true values was 0.948 9. It is feasible to appling the above established method to determination of chemical constituents in Chinese materia medica. Conclusion Compared with other methods, the method is simple, rapid, high efficient, low expenditure, no pollution and with preparation undone and is suit for large quantity of unknown samples.
