Embodiment 1

[0040] The deer blood meal tested was collected in July 2010.

[0041] (1) Grind the dried deer blood powder, pass through a 100-mesh sieve, add it to KBr for grinding, press into tablets, and measure its infrared spectrum-such as figure 1 As shown, the wave number of the infrared spectrum peak is 3321.04cm -1 、3078.94cm -1 、2958.91cm -1 、2863.23cm -1 、1654.83cm -1 、1541.18cm-1 、1453.60cm -1 、1396.58cm -1 、1308.29cm -1 、1242.80cm -1 、1154.84cm -1 、1088.48cm -1 、710.33cm -1 、602.47cm -1 、562.42cm -1 、507.51cm -1 , the specific peak intensity and peak shape are subject to the spectrum.

[0042] (2) Crush the dried deer blood powder, pass through a 100-mesh sieve, weigh 1.00g, use petroleum ether (60-90°C) to make up the volume, use ultrasonic waves to extract at room temperature for 20min, centrifuge, evaporate the solvent to dryness, and obtain the petroleum ether extract , measure its infrared spectrum with KBr sheet - such as figure 2 As shown, the wavenumber...

Embodiment 2

[0049] The deer blood meal tested was collected in Jilin Deer Industry Company in January 2010.

[0050] (1) Crush the dried deer blood powder, pass through a 100-mesh sieve, add it into KBr for grinding, press into tablets, and measure its infrared spectrum. The wavenumber of the infrared spectrum peak is 3323.37cm -1 、3075.09cm -1 、2957.89cm -1 、2860.26cm -1 、1653.65cm -1 、1539.05cm -1 、1454.51cm -1 、1394.65cm -1 、1307.81cm -1 、1243.55cm -1 、1156.78cm -1 、1090.66cm -1 ,708.76cm -1 、603.56cm -1 、560.28cm -1 、505.97cm -1 , The specific peak intensity and peak shape are subject to the spectrum.

[0051] (2) Crush the dried deer blood powder, pass through a 100-mesh sieve, weigh 1.00g, use petroleum ether (60-90°C) to make up the volume, use ultrasonic waves to extract at room temperature for 20min, centrifuge, evaporate the solvent to dryness, and obtain the petroleum ether extract , Measure its infrared spectrum with KBr sheet. The wave number of the infrared ...

Embodiment 3

[0058] The sample tested was "deer blood" powder of unknown origin.

[0059] Pass the dried deer blood powder of unknown origin through a 100-mesh sieve, add it to KBr, grind it, press it into tablets, and measure its infrared spectrum. The wavenumber of the infrared spectrum peak is 3305.41cm -1 、2953.15cm -1 、2861.68cm -1 、1666.00cm -1 、1526.94cm -1 、1448.70cm -1 、1389.63cm -1 、1303.52cm -1 、1240.25cm -1 、1162.48cm -1 、1097.97cm -1 、926.03cm -1 , the specific peak intensity and peak shape are subject to the spectrum.

[0060] Figure 7 : The infrared spectrum of the KBr tablet of deer blood powder from unknown source, the main absorption peaks, peak shape, peak intensity and other information are shown in the figure.

[0061] Figure 8 : Comparison of infrared spectra of real deer blood powder and deer blood powder of unknown origin. Spectrum 1 is the infrared spectrum of real deer blood powder, and Spectrum 2 is the infrared spectrum of deer blood powder from...

Abstract

The invention relates to a method for identifying deer blood powder. The method comprises the following steps: (1) taking known genuine deer blood powder and sample powder, using KBr pellets to respectively measure infrared spectral diagrams of the known genuine deer blood powder and the sample powder, and performing peak position, peak intensity, peak form and wave number contrastive analysis onthe two infrared spectral diagrams; and determining that the sample powder is a counterfeit product if the two infrared spectral diagrams are different completely, and performing the following step for analysis if the two infrared spectral diagrams are similar or the same; and (2) taking the known genuine deer blood powder and the sample powder, respectively performing solvent extraction on the known genuine deer blood powder and the sample powder by using n-hexane, petroleum ether (60-90 DEG C), methanol, ethanol and a mixture of ethanol and water (v / v), respectively determining the infraredspectral diagrams of extracts of the known genuine deer blood powder and the sample powder, and performing two-two peak position, peak intensity, peak form and wave number contrastive analysis on theinfrared spectral diagrams of the extracts of the genuine product and the sample obtained by extraction with the same solvent; and determining that the sample is a counterfeit product if main data inthe contrastive analysis of three and more infrared spectral diagrams with respect to the five solvent extracts is different. By adopting the method, ingredients in the original medicinal material donot need to be separated one by one, and the authenticity of the deer blood powder can be quickly, simply and directly judged without losing the nature of the original medicinal material.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to an identification method for materials derived from animals, in particular to an identification method for authenticity of deer blood meal materials. Background technique [0002] The quality of Chinese medicinal materials is the fundamental guarantee for the modernization of traditional Chinese medicine, and the quality control of Chinese medicinal materials is the key to the development of modern Chinese medicine. The composition of Chinese medicinal materials is complex, and Chinese medicine relies on various chemical components contained in it to exert comprehensive medical effects. Therefore, it is particularly important to identify and evaluate comprehensive indicators of Chinese herbal medicines. Fingerprint of Chinese medicinal materials refers to the characteristic map of a single medicinal material obtained by means of modern analysis techniques such as spect...
