Abstract
The invention relates to a method for extracting effective components of echinacea purpurea by utilizing a microwave technology, and belongs to the technical field of the echinacea purpurea. The invention adopts the technical scheme as follows: by utilizing the microwave extraction technology and by taking an ethanol water solution as solvent, an echinacea purpurea herb raw material is crushed, extracted through microwave and filtered; and filtrate is rotationally evaporated and condensed to obtain effective components of the echinacea purpurea, wherein ethanol water solution is simultaneously recovered while the rotational evaporation is carried out. By designing and exploring the influence of the parameters such as microwave power, radiation time, solvent dosage, soaking time, the crushing degree of the raw materials, and the like on the extraction effect of total flavone in the echinacea purpurea, the optimal process conditions can be determined, and the defects that the traditional ethanol extraction method requires long time and has low extraction rate, the content of the total flavone as the effective component is low, etc. are overcome. The microwave extraction method is suitable for industrial production and has broader development space.
Description
Technical field
The present invention relates to a kind of extracting method of effective ingredients in plant, particularly a kind of Echinacea extraction of effective components more specifically, relates generally to a kind of method of utilizing microwave extraction technology effective component extracting from Echinacea.
Background technology
Echinacea (Echinacea) is a kind of Echinacea plant that originates in North America and Canada south, this platymiscium has 8 kinds and several mutation, present 3 kinds that mainly contain: Echinacea purpurea Moench (Echinaceapurpurea as drug development, be usually said Echinacea), Echinacea angustifolia (Echinacea augustifolia) and white Echinacea (Echinacenpallida).At present, wild amount seldom, they originate in the North America, now Europe and other are regional all an introducing and planting.Ground such as China Beijing, Nanjing, Shanghai and Changsha are also introduced a fine variety and are carried out the GAP kind and plant.The main chemical compositions that Echinacea, Echinacea angustifolia and violet ash awl chrysanthemum contain can be divided into several big classes: polysaccharide and glycoprotein, polar caffeic acid derivant (caffeic acid derivatives), fat-soluble alkylamide (alkamides).Every constituents that different plants contain has difference, and the contained chemical compound of every constituents also is not quite similar.For example, the polarity part that leaches at ethanol mainly contains the caffeic acid derivant, Echinacea angustifolia and violet ash awl chrysanthemum mainly contain Echinacea glycoside (echinacoside), and Echinacea then mainly contains chicoric acid (cichoric acid), can be used as immunomodulator and stimulant.
After the China joined WTO, the Green Trade Barrier of agricultural product frequently occurs, and antibiotic residual quantity exceeds standard and having a strong impact on the international trade of animal products.In addition, in process of production there is high pollution in environment, under the trend that nowadays mankind go back to nature, has the extremely people's favor of active natural product, states such as America and Europe, Japan have strengthened the research to the natural activity product again.Echinacea has long use history in America, U.S. aborigines once were used as Echinacea " cure-all medicine ", is used for treating back of the body saddle skin ulcer, insecticide and venom, blood viral disease disease of infection and wound, flu, headache, horse etc.At present Echinacea in America as immunopotentiating agent and immunomodulator, be used for the treatment of virosis or bacterial acute or various serious bacterial infections of the various antibiotics of chronic respiratory tract infection auxiliary treatment etc., and what really bring into play drug effect is wherein effective ingredient such as polysaccharide, chicoric acid and flavone.How to optimize existing extractive technique, that to greatest extent its extracts active ingredients is come out to become is particularly important.Involved in the present invention is a kind of method of utilizing microwave technology to extract the Echinacea effective ingredient.
Summary of the invention
Involved in the present invention is a kind of method of utilizing microwave technology to extract the Echinacea effective ingredient.Utilize microwave technology to strengthen the extraction process of Echinacea, the extraction ratio height, the time is short, can prepare out high-quality Echinacea product.
1. technical scheme of the present invention is to utilize microwave extraction technology, with the ethanol water is solvent, after the Echinacea pulverizing, microwave extraction, filtration, filtrate is rotated evaporation and concentration, the spissated while of rotary evaporation, reclaim ethanol water synchronously, the weight ratio of Echinacea powder and ethanol water is 1: 5～15, and the ethanol water of adding 40%～80% soaks and adopts microwave to handle after 4～10 hours, the microwave time is 5～15min, and microwave power is 200W～700W.Investigate of the influence of parameters such as microwave power, radiated time, solvent load, soak time, raw material pulverizing degree to total flavones extraction effect in the Echinacea by design, determine that optimum process condition is: the weight ratio of Echinacea powder and ethanol water is 1: 5, the concentration of ethanol water is 60%, soak time is 6 hours, microwave treatment time is 10min, and microwave power is 650W.
2. Echinacea effective ingredient according to claim 1, it is characterized in that: described Echinacea crude drug source is in genus echinacea plant Echinacea Echinacea purpurea, Echinacea angustifolia Echinacea augustifolia and white Echinacea Echinacenpallida.
The invention has the advantages that:
Tradition ethanol extraction method required time is long, and extraction ratio is low, and the functional component general flavone content is low, and the equipment input is bigger.Microwave extract method is greatly increased at above-mentioned everyway, is suitable for suitability for industrialized production, has comparatively wide development space.
The specific embodiment
Embodiment
Get dry Echinacea medical material 20 grams of pulverizing, add 60% ethanol water 100ml, soaked 6 hours, carry out microwave extraction 10min then, microwave power is 650W.Extracting liquid filtering, filtrate is rotated evaporation and concentration, and reclaims the ethanol of evaporation synchronously.The concentrated solution vacuum drying promptly gets the Echinacea effective component extracts.
Claims (3)
1. method of utilizing microwave technology to extract the Echinacea effective ingredient, it is characterized in that adopting microwave extraction technology, with the ethanol water is solvent, after Echinacea herb raw material pulverizing, microwave extraction, filtration, filtrate is rotated evaporation and concentration, the spissated while of rotary evaporation, reclaim ethanol water synchronously, the weight ratio of Echinacea powder and ethanol water is 1: 5～15, the ethanol water of adding 40%～80% soaks and adopts microwave to handle after 4～10 hours, and the microwave time is 5～15min, and microwave power is 200W～700W.
2. Echinacea extract according to claim 1, it is characterized in that: described Echinacea crude drug source is in genus echinacea plant Echinacea Echinacea purpurea, Echinacea angustifolia Echinacea augustifolia and white Echinacea Echinacen pallida.
