Abstract: Objective Using near-infrared consistency to establish model “Plant a product of a regulation.” Methods The Voglibose capsules were respectively scanned with direct contact scanning in the range of 4200-12000cm-1.The consistency test model was established using near infrared diffuse reflectance spectroscopy and OPUS software to analyze with different pretreatment methods. Results The consistency test model can well distinguish the different plant producte of Voglibose capsules. Conclusion The established consistency model can accurately and quickly be used to distinguish different manufactures Voglibose capsules, and have a certain reference value in the first test.
