Embodiment 1

[0026] A method for quickly identifying phenylalanine tablets with a near-infrared consistency model, the specific steps comprising:

[0027] (1) Collect samples of phenylalanine tablets and collect original spectra: Beijing Zhongxin Pharmaceutical Factory, Shanghai Huayuan Anhui Renji Pharmaceutical Co., Ltd., Shanghai Quanyu Biotechnology Queshan Pharmaceutical Co., Ltd., Tianjin Zhongxin Pharmaceutical Group Co., Ltd. Co., Ltd. Xinxin Pharmaceutical Factory and Southwest Pharmaceutical Co., Ltd. produced genuine and qualified samples of phenylalanine tablets. The near-infrared diffuse reflectance spectrum, the spectral scanning range is 12000 cm -1 ~4000cm -1 , with a resolution of 8 cm -1， , the number of scans is 32 times, each sample is measured 6 times, the sample does not need to be processed, the original spectrum is collected by direct contact measurement, and the model is established using the original spectrum; the original NIR images of phenylalanine tablets pro...

Abstract

The invention belongs to the technical field of the medicine detection, and particularly relates to a method for rapidly identifying a phenprobamate tablet by a near-infrared consistency model. The method specifically comprises the following steps: (1) collecting a phenprobamate tablet sample; (2) collecting an original spectrum; (3) establishing a consistency check model; and (4) verifying and detecting. The method is capable of using a near-infrared spectroscopy, establishing the consistency rapid identifying model of brands in allusion to different enterprises, and achieving a purpose of the rapid identification through comparing whether CI limit values of an unknown sample spectrum and a certain group of a reference spectrum have the consistency. The method has the detection functionsof rapidness, accuracy and no damage to the sample, and the method can be used for rapidly identifying the phenprobamate tablets produced by the different enterprises.

Description

technical field [0001] The invention relates to a method for quickly identifying phenylalanine tablets by a near-infrared consistency model, and belongs to the technical field of medical detection. Background technique [0002] Phenprobamate (Phenprobamate), chemical name 3-phenyl-1-propanol carbamate, molecular formula C 10 h 13 NO 2 , is a central skeletal muscle relaxant with a sedative effect, first successfully synthesized by Siegfried in 1960, and first listed in Japan and Germany. Tianjin Zhongxin Pharmaceutical Group Co., Ltd. first obtained the approval document for raw materials in 1981; in the same year, Tianjin Lisheng Pharmaceutical Co., Ltd. obtained the approval document for tablets. This product has only one dosage form of tablet in China, the specification is 200mg. Phenylalanine is a central skeletal muscle relaxant with a sedative effect. It is commonly used clinically for abnormal muscle tension such as muscle spasm and rigidity, muscle pain and neura...
