Establishment of Consistency Test Model for Rhubarb by Near-infrared Spectroscopy / 中国药师

Objective: To establish the consistency test model for rhubarb, and identify the counterfeit accurately and quickly. Methods: Totally 23 batches of rhubarb and its artifacts from different sources were collected. The near infrared spectroscopy was col-lected by a near infrared spectrometer, and a consistency identification model was established by combining with OPUS software. Re-sults: Totally 16 batches of rhubarb were within the ranges of CI limits, while the 7 batches of counterfeit products were all outside the ranges of CI limits. Conclusion: The consistency test model can quickly and accurately identify rhubarb, and can be effectively applied in the screening of drug testing vehicles.
