| Abstract:Objective:To modify a patent method concerning determination of synthetic drugs in traditional chinese medicines based on infrared spectroscopy,in order to improve the accuracy of judgment.Methods: The influences of two different derivative methods and random sampling intervals on prediction were observed.Results:Several parameters were optimized.Results:Better results could be obtained by direct finite difference method(DFDM) or curve fitting method(with small window size),coupled with random sampling intervals extending to negative range.Conclusion: The proposed modification improved the accuracy of the previous patent method. |
