Embodiment 1

[0015] Embodiment 1, the carbon dioxide supercritical extraction method of aromatic xintahua oil using alcohol as an entrainer includes a carbon dioxide supercritical extraction method. The carbon dioxide supercritical extraction method includes a carbon dioxide supercritical extraction device, which first extracts the aromatic xintahua oil The grass is crushed to obtain the whole herb powder of aromatic xintahua, and then the entrainer and the whole powder of aromatic xintaflower are fully mixed evenly, and then a carbon dioxide supercritical extraction device is added for extraction operation to obtain the extract aromatic xintahua oil; the entrainer uses 95 % volume percentage concentration of ethanol aqueous solution.

Embodiment 2

[0016] Example 2, the difference from Example 1 lies in that the powder of the whole fragrant Xintahua herb in Example 2 is obtained by crushing the whole fragrant Xintahua herb through a 40-mesh sieve.

Embodiment 3

[0017] Embodiment 3, the difference from Embodiments 1 to 2 is that the ratio of the aromatic xintahua whole herb of Embodiment 3 to the entrainer is 1 kg: 300 ml to 800 ml.

Abstract

The invention relates to a carbon dioxide supercritical extraction method for extracting Ziziphora bungeana Juz. oil by using alcohol as an entrainer. In the carbon dioxide supercritical extraction method, a carbon dioxide supercritical extraction device is provided. The carbon dioxide supercritical extraction method comprises the following steps of: crushing Ziziphora bungeana Juz. to obtain Ziziphora bungeana Juz. whole plant powder; mixing the entrainer and the Ziziphora bungeana Juz. whole plant powder completely and uniformly; and adding the mixture into the carbon dioxide supercritical extraction device to extract to obtain the Ziziphora bungeana Juz. oil, wherein the entrainer adopts ethanol aqueous solution with volume percentage concentration of 95 percent. Compared with the prior art, the carbon dioxide supercritical extraction method has the advantages that: the advantages of no toxicity, no odor, low price, easiness in recycle and the like are achieved; a large number of organic solvents can be avoided during extraction, and damage to human health and environmental pollution in the extraction process can also be avoided; the flow is simple, time consumption is low, steps of separating and refining are saved, and production cycle is greatly shortened; yield can be effectively increased; and operation difficulty and cost are reduced.

Description

[0001] technical field [0002] The invention relates to the technical field of extracting aromatic xintahua oil by supercritical extraction of carbon dioxide, and relates to a carbon dioxide supercritical extraction method of aromatic xintahua oil using alcohol as an entraining agent. Background technique [0003] From fragrant new tower flowers ( Ziziphora bungeana Juz.) Extracting chemical constituents from the whole herb as medicinal or food additives has become a research hotspot. There are two general categories of traditional extraction methods. One is heating extraction method (decoction, reflux, Soxhlet extraction method); the other is soaking extraction method (Jinze and percolation extraction method). The traditional extraction method extracts the required components as completely as possible from the Extraction from the sample material, but the introduction of harmful components or other impurities cannot be avoided, and the traditional method has disadvantages...
