Embodiment 1

[0039] The deer fetuses tested were collected in July 2010.

[0040] (1) Crush the dried deer fetus, pass through a 100-mesh sieve, add it to KBr for grinding, press into tablets, and measure its infrared spectrum - as figure 1 As shown, the wave number of the infrared spectrum peak is 3300.88cm -1 、2924.12cm -1 、2851.15cm -1 、1743.78cm -1 、1650.25cm -1 、1543.25cm -1 、1454.41cm -1 、1395.39cm -1 、1245.48cm -1 、1033.59cm -1 、565.50cm -1 , the specific peak intensity and peak shape are subject to the spectrum.

[0041] (2) Crush the dried deer fetus, 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, and evaporate the solvent to obtain petroleum ether extract , measure its infrared spectrum with KBr sheet - such as figure 2 As shown, the wave number of the infrared spectrum peak is 2924.82cm -1 、2856.66cm -1 、1741.38cm -1 、1456.44cm -1 、1366.36...

Embodiment 2

[0048] The deer fetuses tested were collected in January 2010.

[0049] (1) Crush the dried deer fetus, pass through a 100-mesh sieve, add it to KBr for grinding, press into tablets, and measure its infrared spectrum. The wavenumber of the infrared spectrum peak is 3299.40cm -1 、2923.58cm -1 、2853.64cm -1 、1744.26cm -1 、1650.67cm -1 、1543.96cm -1 、1455.60cm -1 、1395.39cm -1 、1244.57cm -1 、1034.18cm -1 、566.71cm -1 , the specific peak intensity and peak shape are subject to the spectrum.

[0050] (2) Crush the dried deer fetus, 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, and evaporate the solvent to obtain petroleum ether extract , Measure its infrared spectrum with KBr sheet. The wave number of the infrared spectrum peak is 2924.96cm -1 、2856.91cm -1 、1741.81cm -1 、1456.16cm -1 、1366.36cm -1 、1163.35cm -1 、1100.92cm -1 、1045.71cm -...

Embodiment 3

[0057] The sample tested was "deer fetus" of unknown origin.

[0058] Crush the dried "deer fetus" of unknown origin, 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 7 As shown, the wavenumber of the infrared spectrum peak is 3436.04cm -1 、2923.10cm -1 、2855.63cm -1 、1739.88cm -1 、1643.46cm -1 、1544.11cm -1 、1457.43cm -1 、1370.61cm -1 、1237.15cm -1 、1164.65cm -1 、1096.11cm -1 、721.25cm -1 , the specific peak intensity and peak shape are subject to the spectrum.

[0059] Comparison of infrared spectra of deer fetus powder from unknown sources and genuine deer fetus powder-such as Figure 8 As shown, there are considerable differences in the peak position, peak intensity, peak shape and wave number. Therefore, it is concluded that the "deer fetus" of unknown origin is a fake.

Abstract

The invention discloses a method for verifying a deer fetus, which comprises the following steps: (1) taking known genuine deer fetus powder and sample powder, respectively tabletting by using KBr, measuring infrared spectrograms of the tabletted genuine deer fetus powder and the sample powder, carrying out comparative analysis on the peak positions, the peak strength, the peak forms and the wavenumbers of two infrared spectrograms; if the infrared spectrograms are different, 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 deer fetus powder and the sample powder, respectively carrying out solvent extraction on the known genuine deer fetus 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 the infrared spectrograms of extracts of the known genuine deer fetus 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 deer fetus 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 a method for identifying materials derived from animals, especially a method for authenticating materials derived from deer fetuses. 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 chromatogr...
