preparation example Construction

[0022] The preparation method of the Artemisia argyi essential oil is to dry the Artemisia argyi leaves until the moisture content is lower than 1%, and then crush them with a mechanical crusher until the particle size of the material is 0.1-0.2mm, then pour the powder into a sealed container, and pass in CO 2 , the mass ratio of powder to carbon dioxide is 1:2-3, the temperature is cooled to minus 50°C to minus 40°C, and the pressure is 6-7 atmospheres, so that CO 2 becomes a liquid, the powder is fully infiltrated into the liquid CO 2 After 1-2 hours, release the pressure suddenly to normal pressure, collect the powder, add potassium hydrogen phosphate solution to mix, and adjust the pH of the solution to 4-5, then add cellulase, mix thoroughly, and maintain the temperature at 35- 40°C, after reacting for 4-6 hours, add n-pentane, mix and stir for 15-20min at a temperature of 20-30°C and a pressure of 2-3 atmospheres, and then carry out standing and layering, and the obtaine...

Embodiment 1

[0027] An essential oil, which is composed of 70% mint essential oil, 10% mugwort essential oil, 16% borneol solution and 4% medical alcohol with a volume ratio of 15%.

[0028] Add mint essential oil, mugwort essential oil, borneol solution and medical alcohol into the blender, stir evenly at high speed, and obtain it through precision filtration. The preparation method of the mint essential oil is to dry the mint until the moisture content is lower than 1%. Then use a mechanical crusher to crush the material to a particle size of 0.3mm, then pour the powder into a sealed container, and pass in CO 2 , the mass ratio of powder to carbon dioxide is 1:2.4, the temperature is cooled to minus 45°C, and the pressure is 6.6 atmospheres, so that CO 2 becomes a liquid, the powder is fully infiltrated into the liquid CO 2 After 1.6 hours, release the pressure suddenly to normal pressure, collect the powder, add potassium hydrogen phosphate solution to mix, and adjust the pH of the sol...

Embodiment 2

[0034] The essential oil is composed of 69.5% mint essential oil, 11% mugwort essential oil, 14% borneol solution and 5.5% medicinal alcohol with a volume ratio of 10-20%.

[0035] Add mint essential oil, mugwort essential oil, borneol solution and medical alcohol into the blender, stir evenly at high speed, and obtain it through precision filtration. The preparation method of the mint essential oil is to dry the mint until the moisture content is lower than 1%. Then use a mechanical crusher to crush the material to a particle size of 0.35mm, then pour the powder into a sealed container, and pass in CO 2 , the mass ratio of powder to carbon dioxide is 1:2.4, the temperature is cooled to minus 46°C, and the pressure is 6.5 atmospheres, so that CO 2 becomes a liquid, the powder is fully infiltrated into the liquid CO 2 After 1.7 hours, release the pressure suddenly to normal pressure, collect the powder, add potassium hydrogen phosphate solution to mix, and adjust the pH of the...

Abstract

The invention relates to essential oil and a preparation method thereof. The essential oil contains the following components in volume ratio: 65%-75% of mint essential oil, 8%-12% of folium artemisiaeargyi essential oil, 12%-18% of a borneol solution and 4%-6% of medicinal alcohol, wherein the alcohol concentration of the medicinal alcohol is 10%-20%. The preparation method comprises the steps ofadding the mint essential oil, the folium artemisiae argyi essential oil, the borneol solution and the medicinal alcohol into a stirrer together, uniformly stirring at a high speed, and precisely filtering. The essential oil prepared by virtue of the preparation method is capable of removing peculiar smell, purifying air and refreshing mind; and the preparation and extraction methods are simple and high in extraction efficiency, and the purity of each obtained component is high.

Description

technical field [0001] The invention relates to an essential oil and a preparation method thereof, belonging to the technical field of essential oil preparation. Background technique [0002] Essential oils are volatile aromatic substances extracted from the flowers, leaves, stems, roots or fruits of plants through steam distillation, extrusion, cold soaking or solvent extraction. Essential oils are divided into diluted (compound essential oils) and undiluted (single essential oils), such as cactus seed oil. Essential oils are highly volatile and will evaporate quickly once exposed to air. For this reason, essential oils must be stored in dark bottles that can be sealed. Once the bottle is opened for use, the cap should be replaced as soon as possible. [0003] Not all plants can produce essential oils, only plants with balsamic glands may produce essential oils. The distribution of balsamic glands in different plants is different, and some are on petals, leaves, rhizomes ...
