Problems solved by technology

The disadvantages of the process are: the loss of peony flower head fragrance caused by drying, large investment in equipment, and no product of peony flower aqueous extract
The disadvantages of this process are: high production cost, large investment in equipment, and no such product as peony flower aqueous solution extract
[0006] CN100577783C discloses a method for extracting oil: crush plant seeds to 10-20 meshes, use methyl ether as solvent, according to the material-solvent ratio of 1:2-1:24, the extraction time is 30-120 minutes, and the extraction temperature is 30 The method for extracting and separating the oil in plant seeds under the condition of ~90°C does not involve the extraction of flower essential oil and flower water solution
[0007] CN101484562B discloses a method for extracting highly unsaturated lipids with liquid methyl ether: plants, marine animals, and microorganisms are dried, and the water is 5 to 30% of the weight of the raw material, and the water is used close to the critical CO 2 In the state, the method of extracting the obtained highly unsaturated lipid does not involve the extraction of flower essential oil and flower water solution
[0008] The above methods are either cumbersome, or the essential oil loses part of its aroma, or the equipment investment is large and the production cost is high, or the extraction of flowers is not involved, so a method for extracting peony flower essential oil, aqueous solution, lipid and its separation in one step can make up for the above. Insufficient process method

Abstract

The invention relates to a method for one-step extraction and separation of essential oil, water solution and lipid of fresh peony flowers. The method comprises the following steps: on the basis of taking methyl ether or a mixed liquid of methyl ether, butane, propane and ethanol as a solvent, extracting the preprocessed fresh peony flowers in a sealed state at 10-50 DEG C under the pressure of 0.1-0.2MPa for 10-60 minutes; after the extraction is finished, performing solid-liquid separation, collecting an extraction liquid, and statically layering, wherein the peony essential oil is on the upper layer and the peony flower water solution and the peony flower lipid are on the lower layer; performing negative-pressure concentration on the lower-layer solution, and cooling and recovering a condensed liquid to obtain a peony flower water solution extraction liquid, wherein the concentrated liquid is the peony flower lipid. According to the method, the raw material variety is not limited, raw material resources can be fully utilized, the extraction rate is high, the residue content is low, the process is simple, the efficiency is high, the investment is low, and clean dewatered peony petals (filaments), peony flower essential oil, peony flower water solution extraction liquid and peony flower lipid can be obtained at the same time. The method is suitable for not only the fresh peony flowers but also rose flowers, rosa chinensis flowers, jasmine flowers, tea flowers, lavender and the like, the production cost is low, and the competitive advantage in market is remarkable.

Description

technical field [0001] The invention relates to a method for extracting peony flower essential oil, aqueous solution, lipid and separation thereof in one step. Background technique [0002] Peony is the national flower in my country, and it was just for viewing in the past, without further development and utilization of peony's economic value. Peony flower essential oil and aqueous solution are mainly used in cosmetics. The extraction and separation of peony flower essential oil, aqueous solution and lipid will have a certain role in promoting the development of peony industry. [0003] CN102080018A discloses a preparation method of peony essential oil: fresh flowers are pickled with 10% NaCl, steam distillation, water molecule interception method for impurity removal, ethyl acetate extraction, ethyl acetate recovery under reduced pressure, steam distillation, anhydrous sulfuric acid Sodium dehydration, filtration and other methods for preparing peony essential oil. This p...
