Problems solved by technology

But using this method steps are loaded down with trivial details, and cost is high, and the ergosterol content that obtains is few, and yield is relatively low, and 3.5kg dry armillaria fermented culture only obtains 140mg ergosterol, and this limits the further research and application of ergosterol greatly

Abstract

The invention provides an extraction method of an ergosterol monomer compound in Armillarialuteo-virens. The method includes: taking an Armillarialuteo-virens fruit body as the raw material, grinding the raw material into powder, then conducting extraction with ethyl acetate, and carrying out concentration into paste; conducting dissolving with a n-hexane-ethanol solvent; conducting one-dimensional liquid chromatography separation: employing a Silica chromatographic column, adopting a binary mobile phase with n-hexane as the phase A and ethanol as the phase B, performing gradient elution with phase B at a concentration ranging from 0% to 75%, and collecting the 8-11min eluent; performing dissolving with an ethanol-n-hexane solvent; carrying out two-dimensional liquid chromatography separation: adopting a Silica chromatographic column, employing a binary mobile phase with n-hexane as the phase A and ethanol as the phase B, performing isocratic elution with phase B at a concentration of 2-6%, collecting the 12-15min eluent, and performing evaporation concentration to obtain ergosterol. The separation method has the advantages of stability, high repeatability, large preparation capacity, simple operation and time saving, low cost, and high ergosterol extract rate. The target object has an inhibiting effect on lung cancer A549 cells and liver cancer Hep-G2 cells, and has anticancer drug development potential.

Description

technical field [0001] The invention relates to the technical fields of medicinal chemistry and biomedicine, in particular to a method for extracting ergosterol monomeric compounds from Armillaria chrysanthemum and the application of the ergosterol monomeric compounds in preparing anti-liver cancer drugs and anti-lung cancer drugs. Background technique [0002] Armillaria luteo-rivens, also known as chanterelles, golden mushrooms, and yellow rings, belongs to Basidiomycotina, Phytomycetes, Agaricaceae, White Mushrooms, and Armillaria. The fruiting body of Armillaria chrysogenum is medium and large, the cap is flat hemispherical to flat, with a diameter of 5-12cm, the edge of the cap is involuted, and the epidermis is cracked to form ciliated posterior phosphorus sheets arranged in a near ring. The gills are similar to the cap color, slightly dense, curved, and unequal in length. The stipe is cylindrical, the stem is enlarged, 2-10cm long, 2-2.5cm in diameter, white or yello...
