Problems solved by technology

At present, the extraction of cinnamon oil is generally: steam distillation and organic solvent extraction. Among them, the use of steam to extract cinnamon oil has a low oil yield, generally 0.5%-2.0%, high cost, and high production temperature. 1. The heat-sensitive substances in cinnamon oil are easy to oxidize and dissipate, and the active ingredients of cinnamon oil are seriously damaged; and the cinnamon oil obtained by extraction with organic solvents cannot be guaranteed to be pure and natural, and there are organic solvents in it. Hazards to human body and environment

Embodiment 1

[0023] A method for extracting cinnamon oil with supercritical carbon dioxide, the method includes the following steps:

[0024] Step 1: Harvest the osmanthus leaves in the morning in summer and autumn, put them in a bamboo basket, spread them into a thin layer, and dry them in the shade for 12-16 days at room temperature. Keep the osmanthus leaves natural green during the shade and remove them. Put the brown and black cassia leaves and impurities in a clean container and keep tightly closed for later use;

[0025] Step 2: Take the cinnamon leaves processed in step 1 and send them to a pulverizer to pulverize to obtain cinnamon leaf powder, and control the crushed particle size to 20 meshes for use;

[0026] Step 3: Take 200g of the cinnamon leaf powder obtained in step 2 into the extraction kettle, and add ethanol as an entrainer to the extraction kettle, and the amount of ethanol added is 400 mL ethanol;

[0027] Step 4: Pour carbon dioxide into the extraction kettle at a flow rate ...

Embodiment 2

[0036] A method for extracting cinnamon oil with supercritical carbon dioxide, the method includes the following steps:

Abstract

The invention relates to a method for extracting cinnamomum micranthum hagata oil by using supercritical carbon dioxide and the cinnamomum micranthum hagata oil. The cinnamomum micranthum hagata oil comprises the following components by weight: 25 to 30 percent of cineole, 23 to 25 percent of terpinyl acetate, 13 to 15 percent of linalool, 12 to 13 percent of isoeugenol methyl ether, 5 to 7 percent of alpha-terpineol, 3 to 5 percent of eugenol, 2 to 4 percent of beta-phellandrene, 3 to 5 percent of alpha-cadinene and 2 to 4 percent of geraniolene. The method and the cinnamomum micranthum hagata oil have the advantages that the method is simple, convenient to implement and control and low in production cost, damage to active ingredients of the cinnamomum micranthum hagata oil, organic solvent residues and harm to human bodies and the environment are avoided, and the obtained cinnamomum micranthum hagata oil is purely natural and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to the separation and purification of plant active ingredients, in particular to a method for extracting cinnamon oil with supercritical carbon dioxide and the cinnamon oil. Background technique [0002] Fragrant osmanthus is a lauraceae plant, an evergreen small tree, up to more than 9m, with an oval crown, green twigs, and the whole plant has fragrance. The leaves are alternate, leathery, broadly lanceolate, with wavy edges, and mellow. Unisexual flowers, dioecious, umbel clusters between leaf axils, small flowers light yellow. Drupe ellipsoid, purple-brown when ripe. The flowering period is four months, and the fruiting period is nine months. Cinnamon branches and leaves can be extracted to obtain essential oil. Cinnamon oil is a light yellow liquid with a special aroma and a slightly spicy taste, a bit like cinnamon essential oil, and it evaporates quickly...
