Problems solved by technology
[0004] In the domestic rose industry, rose hips, rose leaves, rose pruning branches, crude oil extracted from roses and residues after purification have not been effectively utilized, resulting in a large waste of rose resources
In China, roses are the main source of essential oils, the extraction yield is low, and the high-purity rose essential oil obtained after purification is even lower; the components of the extracted rose essential oil are not balanced, and the aroma is not outstanding. Due to the constraints of rose varieties, some rose essential oils cannot edible

Embodiment
[0060] Such as figure 1 As shown, a method for rose extract supramolecular self-assembly and preparation of rose essential oil and nanomaterials, the specific detailed steps are as follows:
[0061] In the first step, the conventional extraction method of water distillation is used to obtain the rose liquid phase components and the remaining solid phase slag. The specific steps taken are:
[0062] (1) Selection of raw materials for roses: roses are fresh flowers or dried flowers, which are required to be clean and free of impurities;
[0063] (2) Feeding of roses: put roses in a stirring and mixing high-pressure reactor. Wherein, the use of dried roses as raw materials requires deionized water to be injected into the stirring and mixing high-pressure reactor, and the ratio of dried roses to water is 1:2-3. When fresh roses are used as raw materials, the moisture of fresh roses is used, and there is no need to add water to the stirring and mixing autoclave;
[0064] (3) Rose...

Abstract
The invention discloses a method for supramolecular self-assembly of a rose extract and preparation of rose essential oil and a nano material, wherein the method mainly comprises the following steps: respectively pre-extracting a rose liquid-phase component and a rose hip liquid-phase oil component; uniformly mixing the rose solid-phase residues and the rose hip solid-phase pomace with crushed rose leaves, rose branches and rose roots to obtain a solid-phase mixture; extracting the solid-phase mixture by using a water enzymatic method to obtain a liquid-phase mixed component, and remaining solid-phase dregs for later use; homogenizing and mixing the rose liquid-phase component, the rose hip liquid-phase oil component and the liquid-phase mixed component to obtain a rose all-component mixture, performing ultrasonic treatment, and performing supramolecular self-assembly to obtain a fluid substance; purifying the rose essential oil from the fluid substance obtained by supramolecular self-assembly; and preparing a nano biological medicine material by using the residues after the rose essential oil is purified. The final products prepared by the method are high-purity rose essential oil, carbon nanomaterials and nano biomedical materials, and have a good market application prospect.
Description
technical field [0001] The invention belongs to the technical fields of molecular biology, supramolecular chemistry and nanomaterials, and in particular relates to a method for rose extract supramolecular self-assembly and preparation of rose essential oil and nanomaterials. Background technique [0002] Rose essential oil is a group of safe, non-toxic, volatile substances with special fragrance extracted from roses. At present, it is mainly extracted by steam distillation and subcritical extraction. The chemical composition is extremely complex. The main active substances are terpenes, alcohols, esters, ethers, aldehydes and alkanes. Mao alcohol, geraniol, phenylethyl alcohol, linalool, eugenol, rose ether, etc. Rose essential oil is stable in nature and has good antioxidant, antidepressant and antibacterial activities. As a natural flavoring agent, it can be used in medical care, cosmetics and high-end daily chemical products. [0003] Most of the enterprises in my count...
