Embodiment 1
[0068] The method for constructing the multidimensional fingerprint of the polysaccharide of Cordyceps militaris comprises extracting the polysaccharide of Cordyceps militaris from Cordyceps militaris, and subjecting the extracted polysaccharide of Cordyceps militaris to UV absorption spectrum fingerprint analysis, Fourier transform infrared spectrum fingerprint analysis and high performance gel permeation chromatography fingerprint Analyze, obtain the UV spectrum standard fingerprint of Cordyceps militaris polysaccharide, the IR spectrum standard fingerprint and the multidimensional fingerprint construction method of HPGPC chromatographic standard fingerprint, comprise the steps:
[0069] Cordyceps militaris raw materials: 10 groups of Cordyceps militaris raw materials from different origins are from Guangdong, Jilin, Fujian, Hebei and other places.
[0070] (1) Preparation of polysaccharide from Cordyceps militaris
[0071] Take 50 g of dried Cordyceps militaris, crush them,...
Embodiment 2
[0109] Example 2, Multi-dimensional fingerprint analysis of a polysaccharide sample of Cordyceps militaris from a certain production area in Guangdong
[0110] 1. Preparation of polysaccharide from Cordyceps militaris from a place in Guangdong
[0111] Take 50 g of dried Cordyceps militaris from a place in Guangdong, crush them, add absolute ethanol at a ratio of 1 g to 10 mL of solid to liquid, extract at 80°C for 2 h, and repeat the extraction twice after filtration to remove the fat-soluble compounds contained therein. Ethanol was evaporated, and the residue of medicinal materials was added to distilled water according to the ratio of material to liquid: 1g: 20 mL, and extracted with a 260 W ultrasonic extractor at 80°C for 15 min, then extracted in a water bath at a constant temperature of 80°C for 2 h, and repeated extraction twice after filtration. The combined water extracts were concentrated under reduced pressure using a rotary evaporator to one-eighth of the volume o...
Embodiment 3
[0121] Example 3, Multidimensional Fingerprint Analysis of Cordyceps militaris Polysaccharide Sample from a Certain Production Area in Henan
[0122] 1. Preparation of polysaccharide from Cordyceps militaris from a place in Henan
[0123] Take 50 g of dried Cordyceps militaris from a place in Henan, crush it, add absolute ethanol at a solid-to-liquid ratio of 1 g: 10 mL, extract at 80 °C for 2 h, filter and repeat the extraction twice to remove the fat-soluble compounds contained in it. Ethanol was evaporated, and the residue of medicinal materials was added to distilled water according to the ratio of material to liquid: 1g: 20 mL, and extracted with a 260 W ultrasonic extractor at 80°C for 15 min, then extracted in a water bath at a constant temperature of 80°C for 2 h, and repeated extraction twice after filtration. The combined water extracts were concentrated under reduced pressure using a rotary evaporator to one-eighth of the volume of the water extracts. Add absolute ...
