Embodiment 1

[0030] Acousto-optic tunable filter near-infrared spectroscopy technology for rapid qualitative analysis of Chinese patent medicines, taking Compound Danshen Tablets as an example, the specific steps are as follows:

[0031] 1) Collect samples of compound Danshen tablets from different manufacturers, grind them into powder state, sieve with 80 mesh, and weigh about 5 grams, and use them as calibration set samples for model building.

[0032] 2) Use the AOTF-NIR spectrometer to collect the spectral data of each sample in the calibration set by means of diffuse reflectance.

[0033] 3) Perform spectral processing on the original transmission spectrum of the calibration set sample obtained by scanning, convert the transmission spectrum into an absorption spectrum, and then perform first-order derivative processing to eliminate the influence of noise and baseline drift, and finally convert it into a chemometric software that can Identify the data format, open the software, and imp...

Abstract

A method uses acousto-optic adjustable filter near infrared (AOTF-NIR) spectrum technique in quick qualitative analysis of proprietary Chinese medicine. Near infrared spectrum containing rich information of medicine is achieved by AOTF-NIR spectrum technique and computer etc. Collects NIR spectrum of correcting set samples by AOTF near infrared spectrometer and builds qualitative analysis model by principle component analysis (PCA) to analyze. Base on the invention, quick qualitative analysis for other proprietary Chinese medicine and on-line monitoring method in key segments of proprietary Chinese medicine production are realized, which advances research technique development of proprietary Chinese medicine.

Description

1. Technical field [0001] The invention relates to a method for qualitative analysis of Chinese patent medicines, in particular to a method for rapid qualitative analysis of Chinese patent medicines using near-infrared spectroscopy with an acousto-optic tunable filter. 2. Background technology [0002] At present, there are new research results emerging in the field of near-infrared (NIR) spectral analysis technology at home and abroad, and these results play an important role in industrial production such as food, medicine, and tobacco.
