Identification of Ginkgo Biloba Leaf Extract Tablets Based on Near-infrared Spectroscopy Consistency Test Model
Objective To establish a consistency testing model for imported ginkgo biloba leaf extract tablets using near-infrared spectroscopy(NIR)method.Methods Spectral data were collected from 46 batches of ginkgo biloba leaf extract tablets produced by Company A abroad.The OPUS7.8 spectral analysis software was used to preprocess the modeled spectra with second-order derivative and vector normalization.Ginkgo biloba leaf tablets of the same specification from different domestic enterprises were used to verify the model,and the near infrared consistency test model of ginkgo biloba leaf extract tablets was established.Results The established near-infrared consistency model for samples from Company A abroad can identify the ginkgo biloba leaf extract tablets produced by the manufacturer.Conclusion By using consistency testing methods,a consistency testing model for ginkgo biloba leaf extract tablets produced by Company A abroad has been successfully established,which is suitable for rapid screening of this brand of ginkgo biloba leaf extract tablets.
