specific Embodiment

[0071] In the first aspect, the present invention proposes a method for separating mannitol, adenosine and ergosterol in edible fungi with matrix solid-phase dispersion extraction technology, and proposes a method for separating adenosine and ergosterol in edible fungi with matrix solid-phase dispersion extraction technology. method of purification. According to a specific embodiment of the present invention, the method includes the following steps:

[0072]Weigh an appropriate amount of dried edible fungus powder, add appropriate amount of diatomaceous earth in a mortar according to the mass ratio of 1:5-1:20 (g / g), grind and mix thoroughly (1-3min), and obtain edible fungus-diatom Soil mixed powder, weigh 0.12-0.4g of the powder for later use. Weigh an appropriate amount of ODS filler (1.0-1.5g), soak it in pure methanol overnight for activation, install it in a small solid-phase extraction column (inner diameter 16mm, column height 80mm, 12mL with a sieve plate), settle, t...

Abstract

The invention provides a method for separating mannitol, adenosine and ergosterol in a sample to be detected. The method comprises the following steps: carrying out elution treatment on a sample to bedetected in a solid-phase extraction column by using a first eluent, a second eluent, a third eluent and a fourth eluent in sequence; and respectively collecting an elution product of the first eluent, an elution product of the second eluent and an elution product of the fourth eluent to obtain an eluent containing mannitol, adenosine and ergosterol successively. The first eluent, the second eluent, the third eluent and the fourth eluent are respectively and independently a methanol aqueous solution, an ethanol aqueous solution, an acetonitrile aqueous solution or any combination of the methanol aqueous solution, the ethanol aqueous solution and the acetonitrile aqueous solution. According to the method, the adenosine and the ergosterol in the sample to be detected can be purified at thesame time, and the purity of the obtained adenosine and the purity of the obtained ergosterol are greatly improved.

Description

technical field [0001] The present invention relates to the field of analysis and detection. Specifically, the present invention relates to methods and applications for separating mannitol, adenosine and ergosterol in samples to be tested. More specifically, the present invention relates to separating mannitol, adenosine and ergot in samples to be tested. A method for sterols and a method for detecting the contents of mannitol, adenosine and ergosterol in a test sample. Background technique [0002] Ergosterol and mannitol are important pharmaceutical and chemical raw materials, widely used in food, medicine and chemical industries. Mannitol is a good diuretic in medicine, reducing intracranial pressure, intraocular pressure and treating kidney medicine, dehydration medicine, sugar substitute, and also used as an excipient for tablets and a diluent for solid and liquid. Adenosine is recognized as an important regulator of neurotransmission and is involved in many physiologi...
