Embodiment 1

[0022] A preparation method of mugwort essential oil, said preparation method comprising the following steps:

[0023] The original leaves of mugwort were washed and soaked in deionized water at 10° C. for 5 minutes, crushed and passed through a 100-mesh sieve to obtain coarse powder of mugwort. Inject deionized water into the above-mentioned mugwort coarse powder to make the original pulp, mix the original pulp with the enzymatic hydrolysis solution added with cellulomycetes to make slurry a, and inject the slurry a into the reaction kettle, control the temperature at 40 ℃, rotation speed 200r / min, keep for 2 hours, filter and dry to get mugwort fine powder; extraction: put mugwort fine powder into the reaction kettle, place it in a water bath through the reaction kettle, use a high-pressure pump at a speed of 10ml / min from The bottom of the reactor is fed with CO into the reactor 2 , adjust the temperature of the reaction system to 50°C and the pressure to 8MPa, and extract...

Embodiment 2

[0026] A preparation method of mugwort essential oil, said preparation method comprising the following steps:

[0027] washing and soaking the original leaves of mugwort in deionized water at 20°C for 10 minutes, crushing and passing through a 100-mesh sieve to obtain coarse powder of mugwort; injecting deionized water into the coarse powder of mugwort to make a puree, and mixing the puree with Add the enzymatic hydrolysis solution of cellulomycetes and mix to make slurry a, and inject the slurry a into the reaction kettle, control the temperature at 60°C, and the rotation speed at 500r / min, keep it for 3 hours, filter and dry, and obtain mugwort fine powder; Add mugwort powder into the reactor, place it in a water bath through the reactor, and use a high-pressure pump to feed CO into the reactor from the bottom of the reactor at a speed of 30ml / min. 2 , adjust the temperature of the reaction system to 70°C and the pressure to 12MPa, and extract the mugwort fine powder statica...

Embodiment 3

[0030] A preparation method of mugwort essential oil, said preparation method comprising the following steps:

[0031] Wash and soak the original leaves of mugwort in deionized water at 20°C for 10 minutes, crush and pass through a 100-mesh sieve to obtain mugwort coarse powder; inject deionized water into the above-mentioned mugwort coarse powder to make a puree, add cellulosic mold Add ZnCl to the enzymolysis solution 2 The aqueous solution, the slurry is mixed with the enzymolysis solution added with metal salts to make slurry a, and the content of deionized water is controlled to make ZnCl 2 The concentration in slurry a is 0.3×0 -3 mol / L, inject the slurry a into the reaction kettle, control the temperature at 45°C and rotate at 300r / min, keep it for 3 hours, filter it, and vacuum freeze-dry it at -10°C to obtain mugwort fine powder; add mugwort fine powder to In the reactor, place it in a water bath through the reactor, and use a high-pressure pump to feed CO into the ...

Abstract

The invention relates to a preparation method of artemisia argyi essential oil. The preparation method comprises the steps of carrying out physical smashing to obtain crude artemisia argyi powder; carrying out enzymolysis treatment to obtain fine artemisia argyi powder; then, carrying out supercritical CO2 extraction and oil-gas separation to obtain the artemisia argyi essential oil. The artemisia argyi essential oil extracted by using supercritical CO2 as an extracting agent is low in extraction temperature, so that thermosensitive substances are effectively prevented from being oxidized and dissipated, and the essential and pure components in a stock solution and the essential oil are remained to the maximum extent; according to the preparation method, extraction and separation steps are combined into one step, and CO2 which is in the supercritical state flows out and is rapidly gasified to ensure that gas-liquid separation of CO2 and an extract is rapidly generated and CO2 and the extract are immediately separated, so that the oil yield is high, and the purity of the extract is high; in addition, CO2 belongs to a noncombustible gas and is tasteless, odorless, nontoxic and good in safety, so that the extracted artemisia argyi essential oil is particularly suitable for the fields of medical treatment, sanitation and daily chemical products.

Description

technical field [0001] The invention relates to a preparation method of essential oil, in particular to a preparation method of mugwort essential oil. Background technique [0002] Artemisia argyi (scientific name: Artemisia argyi), also known as mugwort, mugwort, mugwort, curb grass, moxibustion grass or mugwort, is a perennial herb belonging to the family Asteraceae. There are wild ones in Hainan Island. The whole plant of mugwort has a special aromatic smell and has the effect of sleeping, helping sleep and relieving fatigue; traditional Chinese medicine uses the whole herb as medicine, which has the functions of warming the meridian, dehumidifying, dispelling cold, stopping bleeding, reducing inflammation, relieving asthma, relieving cough, preventing miscarriage, and anti-allergy . Mugwort is closely related to the traditional cultural life of our people. The purpose of putting mugwort at home during the Dragon Boat Festival to avoid plague, repel mosquitoes and flies...
