Description
Technical field
The present invention relates to plant extract and application thereof, be specifically related to Radix Carpesii extract and its preparation method and application.
Background technology
Since the forties in 20th century, chemical pesticide is because it is wide in variety, instant effect, easy to use, lower-price characteristic
And in pesticide market, occupy leading position.But, due to people to the unreasonable use of chemical pesticide and pesticide inherently
Shortcoming.Chemical pesticide is caused in use to create the problems such as environmental pollution, person poultry poisoning, pesticide residues.Along with people are raw
The raising of bioplasm amount and the enhancing of environmental consciousness. person poultry safety, biological pesticide pollution-free, low toxicity, low-residual are become by exploitation
New focus for pesticide field research.Botanical pesticide is as a part for biorational pesticide, and its developmental research is always
One of hot subject of novel pesticide research.Botanical pesticide derives from nature, can degrade at nature. typically do not pollute the environment
And agricultural product, in environment and human body, the probability of accumulation toxicity is little, comparatively safe to people and domestic animal, injures pest natural enemy
Little, there is the feature of low toxicity, low-residual, it is possible to keeping the high-quality of agricultural product, therefore botanical pesticide has wide market.
In recent years, the most many scholars investigated and have studied antibacterial, the bactericidal activity of some plant extracts.Some
Research shows, plant source presses down (killing) fungus matter and may act on multiple structures of somatic cells, and microorganism produces the risk of resistance relatively
Little.
Botanical fungicide has effect wide spectrum, rapid without sharp crest Vertebrate toxicity or phytotoxicity, environment degradable
And aboundresources, the advantage such as renewable, therefore the development and application to botanical fungicide has boundless prospect.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides Radix Carpesii extract and its preparation method and application.
The technical scheme is that Radix Carpesii extract, the root of Radix Carpesii, stem, leaf and/or seed make after extracting
?.
The preparation method of Radix Carpesii extract, comprises the following steps: step one, by dry Radix Carpesii root, stem, leaf and/
Or seed pulverizing, add 80%～the ethanol of 95% extracts, collect filtrate, obtain Radix Carpesii crude extract；Step 2, Radix Carpesii is thick
Extract extracts through ethyl acetate, obtains Radix Carpesii antimicrobial extract.
Further improvement of the present invention includes:
Described step one is repeatedly extracted and is repeatedly no longer changed to lixiviating solution color, and merging filtrate obtains extracting solution, this is carried
Take liquid and be condensed into dilute extractum, obtain Radix Carpesii crude extract.
In described step 2, Radix Carpesii crude extract ester extract after ethyl acetate extracts sloughs color through macroporous adsorbent resin
Element, then through ethyl acetate purification process.
Invention further provides Radix Carpesii extract preparation preventing and treating ash arrhizus bacteria, Fulvia fulva, Fructus Lycopersici esculenti early
Application in epidemic disease bacterium, cucumber fusarium axysporum, target bacterium and/or P. capsici medicine.
Present invention also offers the preparation method of bactericidal microemulsion containing Radix Carpesii extract, in a kettle., first will
Radix Carpesii extract, insecticides adjuvant is dissolved in ethyl acetate solvent, under the conditions of 40 DEG C～50 DEG C, in the case of high-speed stirred
Gained solvent is added in distilled water, permanent stirring 1h, obtain Radix Carpesii bactericidal microemulsion.
The bactericidal microemulsion containing Radix Carpesii extract prepared according to the method described above.
Containing the bactericidal microemulsion of Radix Carpesii extract, include according to a point percentage by weight: Radix Carpesii extract 1～3 parts,
Solvent 1～2 parts, water 3～5 parts, insecticides adjuvant 1～2.
The present invention compares with antibacterial commonly used in the prior art, has a following features:
The material that reactive compound in the most environmentally safe Radix Carpesii antibacterial is naturally-occurring, derives from nature,
Long-term evolutionary process has defined its intrinsic participation energy and material cyclic metabolic pathway, thus use with environment in or
On plant, noresidue, will not cause biological concentration:
2. pair non-target organism is comparatively safe；
3. the mechanism of action of pair phytopathogen is different from conventional pesticide, uses rear pathogen to be difficult to it and produces drug resistance
Property, pathogen also there is is retarding action to the Drug resistance of conventional sterilization agent.
The Radix Carpesii antibacterial of the present invention is environmentally safe, and the reactive compound in Radix Carpesii antibacterial is naturally-occurring
Material, derives from nature, has defined its intrinsic participation energy and material cyclic metabolic pathway in long-term evolutionary process,
So being applied in environment or on plant, noresidue, biological concentration will not be caused；Comparatively safe to non-target organism；To plant
The mechanism of action of pathogen is different from conventional pesticide, uses rear pathogen to be difficult to it and develops immunity to drugs, to pathogen to routine
The Drug resistance of antibacterial also has retarding action.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is elaborated.
Embodiment 1: the preparation of Radix Carpesii antibacterial activity extract:
Take Radix Carpesii dry sample 100kg, the alcohol reflux adding 70% 2 times, add the ethanol of 800kg 70% for the first time, the
Secondary adds the ethanol of 600kg 70%, filters, united extraction liquid, and extracting solution reclaims ethanol and is concentrated into the dilute of relative density 1.05
Extractum, is extracted with ethyl acetate to obtain ethyl acetate phase by this dilute extractum, and ethyl acetate crosses D101 macroporous adsorbent resin mutually, first uses
This 30% ethanol elution, to colourless, is discarded by the ethanol elution of 30%, then the ethanol elution with 85% is the most colourless, collects this
85% ethanol elution, reclaims ethanol and is condensed into the thick paste of relative density 1.25, and vacuum drying obtains and carries containing Radix Carpesii is antibacterial
Take thing (based on lactone, mass fraction is not less than 60%).
Embodiment 2: the preparation of Radix Carpesii bactericidal microemulsion:
