Problems solved by technology

The report focuses on the research on the medicinal effect of active substances, and the research on the extraction process is not comprehensive enough, and the utilization of the residue after extraction is not considered, which is easy to cause secondary pollution
[0007] To sum up, among the existing methods for the extraction of effective components in Artemisia stalks and the resource utilization of straws, most of them focus on a certain type of monomeric compounds, while few phenolic acids and total flavonoids are considered. In addition, the existing methods The amount of organic solvent used is large, the process operation is cumbersome, the yield is low, and the resource utilization of the residue after extraction is not considered, resulting in serious waste of resources and pressure on the environment.

Embodiment 1

[0033] Take 500g (absolutely dry) Artemisia stalks, put them in a reactor after being crushed through a 40-mesh sieve, add 4000mL of 90% (volume fraction) methanol aqueous solution, heat in a water bath at 60°C for 1h, collect the extract by filtration, and filter the filtrate to Press and concentrate to dryness to obtain the extract extract; redissolve the obtained Artemisia stalk extract extract with deionized water as a sample solution, and add it to a macroporous resin column (HPD-600 or AB-8). After reaching adsorption equilibrium (at a temperature of 20° C.), wash the column with 2BV of deionized water, then carry out isocratic elution with an ethanol solution with a volume fraction of 30%, collect the ethanol eluate, and concentrate the eluate under reduced pressure to nothing. Alcoholic smell, to obtain a concentrated eluent; the obtained concentrated eluent was mixed with an equal volume of ethyl acetate, extracted 3 times, and the aqueous phase and ethyl acetate phase...

Embodiment 2

[0036] as attached figure 1 As shown in the process flow, take 1 ton of air-dried artemisia stalks, put them in a reactor after being crushed through a 40-mesh sieve, and place them in a reactor according to the liquid-solid ratio of 12:1 (m 3 / ton) add methanol solution with a volume fraction of 50%, heat in a water bath at 90°C for 4h, filter and collect the extract, and concentrate the filtrate to dryness under reduced pressure to obtain the extract; Reconstitute with water as the sample solution, add it to the macroporous resin column (HPD-600 or AB-8), when the adsorption equilibrium is reached (at a temperature of 20°C), wash the column with 5BV deionized water, and use a volume fraction of Carry out isocratic elution with 50% ethanol solution, collect the ethanol eluate, concentrate the eluate under reduced pressure until it has no alcohol smell, and obtain a concentrated eluate; the obtained concentrated eluate is mixed with an equal volume of ethyl acetate, Extract ...

Abstract

The invention discloses a method for utilizing all components of artemisia selengensis straws. Waste artemisia selengensis straws are taken as raw materials and solvent extraction is combined with adsorbent resins for refining, so that high-purity phenolic acids and flavonoid matters can be extracted and separated; and meanwhile, the extracted residue is subjected to anaerobic digestion so as to prepare methane and then the residue after preparing methane is prepared into organic fertilizer. According to the method provided by the invention, the use value of the artemisia selengensis straw is increased and the method is easily industrial popularized.

Description

technical field [0001] The invention relates to a method for utilizing all components of artemisia stalks, and belongs to the technical field of resource utilization of waste biomass. Background technique [0002] It is recorded in "Qi Min Yao Shu" of the Northern Wei Dynasty and "Compendium of Materia Medica" of the Ming Dynasty. In addition to being used as food, it also has strong pharmacological activity. The whole herb can be used as medicine. It is flat in nature and sweet in taste. It has the effects of stopping bleeding and reducing inflammation, relieving cough and reducing phlegm, appetizing and invigorating spleen, dispelling cold and dehumidification. It can treat diseases such as weak stomach qi, loss of appetite, edema and puffer fish poisoning. "Compendium of Materia Medica" records that it has the effects of "invigorating the middle and replenishing qi, sharpening the stomach and appetizing the stomach, healing the heart, taking a long time to lighten the bo...
