Abstract
The invention belongs to the field of extraction of plant essential oil and in particular discloses a method for extracting peony essence from fresh peony flowers. The method comprises the following steps: performing supercritical CO2 extraction on the fresh peony flowers as raw materials to prepare peony extract, and extracting the peony extract to obtain the peony essence by employing a molecular distillation method. According to the method, since the fresh peony petals are taken as the raw materials, the spice components, thermal-sensitive substances and other active ingredients in the peony petals are maintained to the greatest extent, desensitization treatment is performed in the extraction process of essential oil, the condition that some people have pollen allergy is avoided; since the peony essential oil is extracted through the supercritical CO2 extraction method, the phenomenon that the thermal-sensitive substances in the peony flowers are lost because of heating in the traditional method is avoided; and meanwhile, the residue problem of the harmful substances caused by extraction by employing an organic solvent and the treatment and recovery problems of the organic solvent are solved, the environmental pollution is reduced, and the energy consumption is reduced.
Description
Technical field
The invention belongs to and from plant, extract essential oil field, relate to a kind of method of extracting peony essential oil from fresh peony flower.
background technology
Tree Peony flower, spend large-scale U.S., flower is elegant and poised, luxurious, is described as the king in spending, because tree peony blooms once every year, only one week florescence, the tender profit of petal, easily mouldy after gathering, be difficult for preserving, brought many difficulties to the research and production of peony essential oil, plants essential oil is in the market by essential oil and chemical additive is composite forms; Essential oil is plant volatile oil, in plant, content is very micro-, expensive, directly, with easily damaging human body, pure plants essential oil molecular weight is little, volatile, not moisturizing, higher-priced plants essential oil mostly is and adds Moisture factor hyaluronic acid, and low to medium price level mostly is the glycerine, propylene glycol, mineral oil, paraffin etc. that add Moisture factor chemosynthesis, and life-time service chemosynthesis essential oil produces untoward reaction to skin.
In peony petal, contain multiple important higher fatty acid, mainly take palmitinic acid, linoleic acid plus linolenic acid as main, unsaturated fatty acids has the blood fat of reduction, prevents arteriosclerotic effect, if linolic acid is essential fatty acid, have in human body and can change arachidonic acid into, for synthetic phospholipid, form cellularstructure, maintain the normal function of all tissues, and synthesis of prostaglandins, be all necessary, linolenic acid is the nutrient substance that body weight for humans is wanted, there is inhibition metastases, reduce Incidence of CHD, improve the effects such as immunizing power; In Tree Peony flower, also containing element and vitamins B and the carotenoid such as protein, polyphenols, potassium, calcium, magnesium, phosphorus, is a kind of natural nutritive health-care material.
Traditional method to extraction of essential oil in plant flower, mostly is solution extraction, and this method is extracted plants essential oil can inevitably affect the unstable component in fresh flower, causes the difference of medicinal extract fragrance and fresh flower fragrance.
CN102080018A discloses the making method of Tree Peony flower essential oil: gather fresh peony petal and add 10% sodium-chlor to pickle, then wet distillation, collect 1-20 and doubly measure distillate, by molecular retention method, carry out removal of impurities, trapped fluid is extracted with ethyl acetate, reduced-pressure backflow ethyl acetate, debris is collected lighter than water, heavier than water cut by wet distillation, with anhydrous sodium sulfate dehydration, filter.The shortcoming of the method is: in the process that adopts sodium-chlor to pickle peony petal, in peony petal, original fragrance component likely can lose, and adopted in the method organic solvent ethyl acetate, organic solvent likely have in product, have residual, also must organic solvent be refluxed and be reclaimed in process of production, power consumption is large, and process is complicated, but also has unsafe factor.
CN102391913A discloses a kind of supercritical extraction method of peony essential oil, the step of the method is: clean removal of impurities, oven dry to its moisture content is less than 7%, pulverize, then by supercritical carbon dioxide extraction, the shortcoming of the method is: be not that to take the Tree Peony flower of fresh firm harvesting be raw material, but will after tree peony root cauline leaf and flower oven dry, process again, adopt the method processing can cause heat-sensitive materials in Tree Peony flower to be damaged, lower boiling aroma component volatilizees, thereby affects the quality of product.
Separately there is the pre-treatment of bibliographical information Tree Peony flower to use cryogenic vacuum lyophilize, freeze temperature-15 ℃, vacuum tightness 15-40Pa, time 6-7 hour.This technique has retained original flavour ingredient of Tree Peony flower to greatest extent, but has energy consumption excessive, is unfavorable for the popularization of suitability for industrialized production.
In above-mentioned Tree Peony flower method of extraction of essential oil, take peony petal as raw material, or the peony petal of take after drying is raw material, and no matter peony petal is in process of growth, or in harvesting process, all inevitably can fall to having pollen, and part population is irritated to peony pollen, in the situation that cannot stopping peony pollen completely, pollen can be along with the leaching process of Tree Peony flower essential oil, no matter adopt which kind of method to extract in the peony essential oil obtaining, all likely can contain residual peony pollen, thereby cause for the crowd of peony pollen allergy equally also irritated to Tree Peony flower essential oil.Not all Tree Peony flower essential oil is all suitable for all people group.
Therefore need to improve for above-mentioned method defect, design a kind for the treatment of process that has fully retained heat-sensitive materials and active substance in Tree Peony flower, Tree Peony flower is extracted, obtain Tree Peony flower essential oil safe, quality better.
Summary of the invention
In order to solve above-mentioned technical problem, the invention discloses and a kind ofly can retain fully heat-sensitive materials in fresh peony flower and the extraction essential oil method of various active substances, the method, with by supercritical carbon dioxide treatment, can be extracted the Tree Peony flower essential oil that quality is high from fresh peony flower.
