Embodiment 1
[0034] (1) The samples of Sword leaf eargrass used were collected from Jinxiu Yao Autonomous County, Guangxi. Take 30 kg of Auricularia agustifolia sample, pulverize it and extract the A. auriculatum and each solvent with ethanol and water with volume concentrations of 95%, 80%, 60%, and 40% respectively as solvents. The mass ratio is 1:8, the extracts are combined, the extracts are combined, concentrated under reduced pressure, and the solvent is recovered until there is no alcohol taste to obtain the total extract.
[0035] (2) Suspend the total extract with water to a concentration of 0.02~1g / ml, and then successively extract with 60~90℃ petroleum ether, chloroform, ethyl acetate and n-butanol, and concentrate under reduced pressure to recover the solvent respectively to obtain petroleum Dry extract of ether, dry extract of chloroform, dry extract of ethyl acetate and dry extract of n-butanol.
[0036] (3) The dry extract of chloroform part was separated by column chromatograph...
Embodiment 2
[0039] (1) Crush the whole E. chinensis and extract it in a solvent. The weight of the solvent is 4-12 times the weight of E. chinensis. The solvent is methanol; the resulting extract is concentrated under reduced pressure and the solvent is recovered to no Alcohol taste to obtain the extract, take a small amount of extract and dry it completely to obtain a dry extract of the extract, and weigh it, and calculate the total net weight of the extract according to the mass of the obtained dry extract of the extract;
[0040] (2) Dilute the extract obtained in step (1) with water according to the actual net weight to an aqueous solution with a concentration of 0.02~1g / ml, and then use the solvent petroleum ether, chloroform, ethyl acetate, n-butanol, which are solvents with increasing polarity, in order Extraction to obtain the corresponding extracts, respectively concentrate the extracts under reduced pressure, and collect the dry extract of chloroform parts;
[0041] (3) Separate and ...
