Embodiment 1

[0021] A kind of Urami volatile oil, its specific preparation steps are:

[0022] 1) Dried Ulagrass harvested in the Northeast to remove impurities, crushed Ulagrass with a plant grinder, passed through a 10-mesh sieve, and soaked in water at 25°C for 2 ~6h.

[0023] 2) Connect the Ula grass soaked in step 1) to the volatile oil extraction device, avoid direct sunlight, stir at a speed of 150~350rpm, and heat for extraction for 5~9h.

[0024] 3) Stop heating, wait for the device to cool down to room temperature, from the upper end of the volatile oil extraction device in step 2), collect the crude extract of Ulagrass volatile oil with a light yellow oil with a special fragrance; at the same time collect the clear and transparent liquid in the volatile oil extraction device , it has been determined that the liquid contains components related to the volatile oil of Uralia pratense.

[0025] The extraction device for the volatile oil of Ulagrass in this example is a 1000 mL vol...

Embodiment 2

[0029] On the basis of Example 1, the process was further optimized.

[0030] The preparation method of this volatile oil is as follows: pulverize the sage, pass through a 10-mesh sieve, soak it in water at 25°C for 3 hours at a material-to-liquid ratio of 1:40 (g / mL), and put it in In the three-necked bottle, connect a volatile oil extraction device, stir at a speed of 200 rpm, heat and extract for 9 hours, stop heating, wait for the device to cool to room temperature, collect a light yellow oily substance with a special fragrance from the upper end of the volatile oil extraction device, and obtain the Ulacao volatile oil crude extract. The calculated extraction rate is 0.05-0.1%. The measured light yellow volatile oil components include hexanal, benzaldehyde, 3,5-octadien-2-one, butyl acrylate, dihydroactinolactone, farnesyl acetone, squalene, etc.

Embodiment 3

[0032] On the basis of Example 1, the process was further optimized.

[0033] Step 3) Continue to cool the obtained pale yellow oil to room temperature, and then place it in the freezer layer of the refrigerator for 10-20 minutes until the oil and water are separated, take out the oil layer and store it in a dark place. Compared with step 3), the purity of the crude extract of volatile oil is higher.

Abstract

The invention discloses carex meyeriana volatile oil and application thereof. The preparation process of the carex meyeriana volatile oil comprises the following steps: crushing carex, soaking for 2-6 hours in water at 24-26 DEG C according to a material to liquid ratio of (1:10)-(1:50), performing stirring heating extraction for 5-9 hours by using a volatile oil extraction device at a rotation speed of 150-350rpm, cooling to the room temperature, and collecting a light yellow oil substance from the upper end of the volatile oil extraction device, thereby obtaining a crude carex meyeriana volatile oil extract. The carex meyeriana volatile oil disclosed by the invention has an antibacterial function and a mite elimination function on escherichia coli, staphylococcus aureus, bacillus pumilus and bacillus subtilis, can be developed into products for eliminating mites and preventing bacteria, and meanwhile can be applied to products for whitening skin, removing beverage and tendering skin.

Description

technical field [0001] The invention relates to the field of preparation and application of natural products, in particular to a cloverleaf volatile oil, which has the functions of removing mites, inhibiting bacteria, whitening, removing freckles and rejuvenating the skin. Background technique [0002] Carex meyeriana Kunth is a perennial herbaceous plant belonging to the genus Carex L. in Cyperaceae. In 1837, it was published in "Enum Ⅱ" in Poland. Volume 12 of "Flora of China" records that it was born in swamps and distributed in humid areas such as Russia (Far East, Siberia), Mongolia, Korea, Japan, and China's Liaoning, Heilongjiang, Jilin, Inner Mongolia, and Sichuan. Ulagrass has a long history of application, and it has been recorded as a shoe lining for hundreds of years. Because of its unique function of keeping warm, breathable, sweat-absorbing, moisture-proof, cold-proof, and anti-bacterial, it is mainly produced in Northeast my country. Ulagrass is an importan...
