Embodiment 1

[0037] The antlers tested were collected in July 2010.

[0038] (1) Crush the dried velvet antler, pass it through a 100-mesh sieve, add it to KBr for grinding, press it into tablets, and measure its infrared spectrum-such as figure 1 As shown, the wave number of the infrared spectrum peak is 3846.54cm -1 、3796.77cm -1 、3398.62cm -1 、3326.36cm -1 、3075.12cm -1 、2927.60cm -1 、2847.00cm -1 、1651.37cm -1 、1547.55cm -1 、1454.38cm -1 、1391.24cm -1 、1329.03cm -1 、1244.65cm -1 、1033.55cm -1 、876.96cm -1 、777.42cm -1 、563.48cm -1 , the specific peak intensity and peak shape are subject to the spectrum.

[0039] (2) Crush the dried antler, 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 wave numb...

Embodiment 2

[0046] The antlers tested were collected in January 2010.

[0047] (1) Crush the dried velvet antler, 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 3845.21cm -1 、3795.46cm -1 、3396.02cm -1 、3326.05cm -1 、3076.43cm -1 、2926.60cm -1 、2846.87cm -1 、1651.71cm -1 、1549.32cm -1 、1454.31cm -1 、1393.39cm -1 、1327.84cm -1 、1246.08cm -1 、1034.27cm -1 、876.16cm -1 、777.38cm -1 、56494cm -1 .

[0048] (2) Crush the dried antler, 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 wavenumber of the infrared spectrum peak is 3408.10cm -1 、2923.90cm -1 、2855.36cm -1 、1742.32cm -1 、1633.09cm -1 、1458.67cm -1 、1370....

Embodiment 3

[0055] The sample tested was "deer antler" of unknown origin.

[0056] Crush the dried "deer antler" of unknown origin, pass it through a 100-mesh sieve, add it to KBr, grind it, press it into tablets, and measure its infrared spectrum-such as Figure 7 As shown, the wavenumber of the infrared spectrum peak is 2914.55cm -1 、2146.82cm -1 、1646.32cm -1 、1370.59cm -1 、1237.79cm -1 、1129.38cm -1 、926.73cm -1 、853.85cm -1 、764.98cm -1 、711.06cm -1 .

[0057] Compared with the infrared spectrum of genuine deer antler - such as Figure 8 As shown, there is a considerable gap in the absorption peak position, peak shape, wave value, peak intensity and other information. Therefore, it is concluded that the "deer antler" of unknown origin is a fake.

Abstract

The invention discloses a method for verifying a young pilous antler, which comprises the following steps: (1) taking known genuine young pilous antler powder and sample powder, respectively tabletting by using KBr, measuring infrared spectrograms of the genuine young pilous antler powder and the sample powder, carrying out comparative analysis on the peak positions, the peak strength, the peak forms and the wave numbers of two infrared spectrograms; if the infrared spectrograms are different completely, the sample powder is a counterfeit, and if the infrared spectrograms are similar or the same, the following step is carried out for analyzing, namely: (2) taking the known genuine young pilous antler powder and the sample powder, respectively carrying out solvent extraction on the known genuine young pilous antler powder and the sample powder by using normal hexane, petroleum ether (60-90 DEG C), methanol, ethanol and a mixture (v / v) of the ethanol and water, respectively measuring infrared spectrograms of extracts of the known genuine young pilous antler powder and the sample powder, and carrying out the comparative analysis pairwise on the peak positions, the peak strength, the wave forms and the wave numbers of the infrared spectrograms of a genuine article and a sample of the same solvent extract; and if main data of three or more than three infrared spectrograms in five solvent extracts are different in the comparative analysis, the sample is a counterfeit. By using the method, the ingredients of a raw medicinal material are not necessary to be separated one by one, and the truth of the young pilous antler can be directly judged fast, simply and conveniently without losing the natural instincts of the raw 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, especially an identification method for authenticity of velvet antler 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 spectrum or c...
