Objective: To establish a fast identification method for the determination of L-ascorbic acid in Vitamin C Yinqiao pian by near-infrared reflectance spectroscopy(NIRS). Methods: According to the characteric peaks of ascorbic acid in the spectrum band of NIR and the results of HPLC,the qualitative model was set up by OPUS software. Results: The near-infrared spectroscopy technology could be used to identificate whether Vitamin C Yinqiao pian contained L-ascorbic acid or not. Conclusion: The results show that the proposed method can be applied for fast detection of L-ascorbic acid and its isomer in the Vitamin C Yinqiao pian.
