Abstract
The invention provides a sarmentosum-containing aromatherapy essential oil and a preparation method thereof, wherein the aromatherapy essential oil comprises the following raw materials in parts by weight: the invention adopts supercritical carbon dioxide to extract the sarmentosum extract, adds compound fruit acid into the extract to promote fragrance, adds the fragrance locking agent, the thickening agent and the like to lead the fragrance to be uniform, slowly releases and increases the diffusion time of the fragrance, and the invention comprises 40-60 parts of the sarmentosum extract, 10-30 parts of compound fruit acid, 5-10 parts of mannitol, 2-8 parts of the fragrance locking agent, 10-26 parts of the emulsifying agent, 0.1-0.5 part of the thickening agent and 3-10 parts of water.
Description
Technical Field
The invention relates to the technical field of aromatherapy, in particular to an aromatherapy essential oil containing sarmentosum and a preparation method thereof.
Background
The sarmentosum (Piper sarmentosum Roxb) is a perennial herb of Piper genus of piperaceae family, is also called as sarmentosum, fructus Piperis Longi, and is widely distributed in Guangxi, guangdong, yunnan, hainan provinces of China, has abundant resources, can be harvested all year round, has the effects of dispelling wind and cold, promoting qi circulation and relieving pain, activating collaterals, relieving swelling and the like, is commonly used for wind-cold cough, abdominal distention, diarrhea and dysentery, swelling of feet after delivery, traumatic injury and the like, has various pharmacological activities, and has the effects of easing pain, resisting viruses, inhibiting fungi, resisting tumors, resisting oxidation, resisting inflammation and the like. The sarmentosum is rich in various active substances such as acids, ethers, alcohols, terpenes and the like.
Aromatherapy is an aromatherapy method for conveying medicinal effects of essential oil by skin system and respiratory system, and by massage, inhalation, hot compress, soaking and fumigation, aromatic essential oil is quickly mixed into human blood and lymph fluid, so as to accelerate metabolism in vivo, promote regeneration of living cells, enhance immunity of body, and regulate nervous system, circulatory system, endocrine system, muscle tissue, digestive system and excretory system of human body; the prior plant extract aromatherapy essential oil has less active reserved components, short fragrance leaving time in the use process, and the volatilization of the fragrance is blocked due to the influence of a solid agent when the solid aromatherapy is prepared, so that the use effect of the aromatherapy is greatly influenced.
Disclosure of Invention
In view of the above, the present invention provides an aromatherapy essential oil containing piper sarmentosum and a preparation method thereof, which solves the above problems.
The technical scheme of the invention is realized as follows: an aromatherapy essential oil containing caulis Piperis Futokadsurae is provided: the material comprises the following raw materials in parts by weight: 40 to 60 parts of sarmentosum extract, 10 to 30 parts of compound fruit acid, 5 to 10 parts of mannitol, 2 to 8 parts of perfume locking agent, 10 to 26 parts of emulsifying agent, 0.1 to 0.5 part of thickening agent and 3 to 10 parts of water.
Further, an aromatherapy essential oil containing sarmentosum: the material comprises the following raw materials in parts by weight: 50 parts of sarmentosum extract, 20 parts of compound fruit acid, 8 parts of mannitol, 6 parts of perfume locking agent, 18 parts of emulsifier, 0.3 part of thickener and 8 parts of water.
Further, the compound fruit acid is citric acid, malic acid and citrus acid with the mass ratio of 1:3-5:2-8.
Further, the emulsifier is xylitol fatty acid ester.
Further, the perfume locking agent is avocado oil or olive oil, and the avocado oil is selected from the European Nuo brand.
