Embodiment 1

[0056] Example 1 Cordyceps sinensis standard spectrum drawing, collection of necessary characteristic peaks of cordyceps sinensis infrared spectrum and common characteristic peaks of cordyceps sinensis infrared spectrum and determination of lower threshold of correlation coefficient

[0057] 1) Sample source and processing

[0058] Select 15 samples of Cordyceps sinensis from Yushu Prefecture in Qinghai, 15 from Guoluo Prefecture, 15 from Hainan Prefecture, 15 from Tibet, 15 from Sichuan and 8 from Gansu, and select samples of uniform size for each origin.

[0059] The sample was processed according to the relevant regulations of the Pharmacopoeia of the People's Republic of China. The insect body part of the sample was naturally dried and then pulverized. The fine powder after passing through a 200-mesh sieve was used for infrared spectrum testing.

[0060] 2) Infrared Spectroscopy Instrument

[0061] All sample tests in the present invention all use the Spectrum One Fourier...

Embodiment 2

[0082] Embodiment 2 The identification of the Cordyceps worm body and the Cordyceps sinensis worm body

[0083] 1) Sample source and processing

[0084] The numbers of commercially available Cordyceps Gurney are G1, G2, G3, and G4.

[0085] The sample was processed according to the relevant regulations of the Pharmacopoeia of the People's Republic of China. The insect body part of the sample was naturally dried and then pulverized. The fine powder after passing through a 200-mesh sieve was used for infrared spectrum testing.

[0086] 2) Infrared Spectroscopy Instrument

[0087] All samples were tested using a Spectrum One Fourier transform infrared spectrometer from PerkinElmer, USA.

[0088] Sample test parameters: spectral scanning range 4000 ~ 400cm -1 , spectral resolution 4cm -1 , each spectrum is accumulated and scanned 16 times, and the interference of carbon dioxide and water vapor is deducted in real time.

Abstract

The invention relates to the field of analytical chemistry, specifically to an infrared spectroscopic analysis and identification method for the polypide of Cordyceps sinensis. The objective of the invention is to overcome the technical problem that whether the polypide of Cordyceps sinensis is true or false is difficult to determine at present. Thus, the invention provides the method for rapid and accurate discrimination of the polypide of Cordyceps sinensis. The method comprises the following steps: a, drafting the standard spectrum of the polypide of Cordyceps sinensis; b, acquiring necessary infrared spectroscopic characteristic peaks and common infrared spectroscopic characteristic peaks of the polypide of Cordyceps sinensis; and c, comparing infrared spectroscopic characteristic peaks and infrared spectroscopic similarity of a detected sample of the polypide of Cordyceps sinensis. The invention provides the novel method for rapid and accurate discrimination of the polypide of Cordyceps sinensis.

Description

technical field [0001] The present invention relates to the field of analytical chemistry. Specifically, it relates to an infrared spectrum analysis and identification method for the body of Cordyceps sinensis. Background technique [0002] Cordyceps sinensis is a complex of the subunit and larvae of Cordyceps sinensis (Berk.) Sacc., a fungus of the ergot family Fungus Cordyceps sinensis (Berk.) Sacc. Ginseng and deer antler are known as the three major tonics in China. [0003] The growth environment of Cordyceps sinensis is special, and it is mainly distributed in alpine meadows and alpine shrubs at an altitude of 3000-5000 meters on the Qinghai-Tibet Plateau in my country. Qinghai, Tibet, Sichuan, Gansu and Yunnan are the main production areas of Cordyceps sinensis. The output and quality of Qinghai ranks first among all provinces and autonomous regions. Yushu and Guoluo are the main production areas of Cordyceps sinensis in Qinghai. Cordyceps sinensis cannot be artifi...
