Embodiment 1

[0028] Determination of the content of rifampicin in rifampin tablets:

[0029] collect inner mongolia ** 50 rifampicin tablets from the pharmaceutical industry were used as samples to be tested, product batch number: 031123. A total of 236 samples of five anti-tuberculosis drugs, rifampicin, isoniazid, pyrazinamide, isoferamide and isoferamide, were used as modeling samples.

[0030] The sample was pulverized and dissolved, and the content of the active ingredient rifampicin in the rifampicin tablets was measured by high performance liquid chromatography.

[0031] Embed the rifampicin tablet sample in the center of the blank plate, put it in the sample tank of the integrating sphere of the near-infrared spectrum detector, use the spectral wavelength of 1500-2000nm through model analysis, and select the spectral passband width as 12nm, and record each sample in the near-infrared spectral region. the absorption spectrum. see picture 1.

Abstract

The invention discloses method of testing effective constituent of near infrared light detection anti tubercular agent. Using the basis of anti tubercular agent action spectrum near infrared light and the measurand information, getting effective constituent (rifampicin,isoniazide or pyrazinamide ) of which by anti tubercular agent action spectrum near infrared light and their background information; achieving the lossless detection the content of effective constituent (rifampicin,isoniazide or pyrazinamide ) in the anti tubercular agent near infrared light complex background by the multi element normalized method of chemometrics. It settles the problem of high cost, long period, medicament cannot use after analyzing etc when analyzing the anti tubercular agent effective constituent in existence, establishing the fast, high pass mete, lossless and needed on-line analysis green medicament analytic method for the anti tubercular agent. The advantages is that the sample pre-processing is easy, the detection is fast and undamaged, the detection time of each sample is shortage of two min; the result is credibility, the error is less than5%.

Description

technical field [0001] The invention discloses a method for non-destructive analysis of anti-tuberculosis drugs by near-infrared spectroscopy, relates to rapid non-destructive detection of the content of active ingredients in anti-tuberculosis drugs, and belongs to the technical field of drug detection and analysis. Background technique [0002] Tuberculosis is one of the main causes of death from a single infection. There are 8 to 10 million new cases each year, and 2 to 3 million deaths due to tuberculosis each year. Tuberculosis causes more deaths among young people than any infectious disease. Rifampicin, isoniazid and pyrazinamide are relatively effective drugs against tuberculosis at present. [0003] At present, the ingredients and background of anti-tuberculosis drugs are complex, and the conventional determination methods of active ingredients rifampicin, isoniazid and pyrazinamide need to separate and measure the ingredients of the sample, such as reversed-phase hi...
