Description
Technical field
The present invention relates to the technical field that insecticide is prepared using plant as raw material, particularly containing walnut peel extract
Insecticide and preparation method thereof.
Background technology
China's plant resources enrich, and a large amount of walnut husk, i.e. green peel of walnut are produced in the walnut harvest season, due to
Green peel of walnut alkalinity is stronger, can neither be used as feed, can not directly make fertilizer, peasant often it is arbitrarily stacked in field,
The edge of a field, roadside or limes marginis；Once raining or green peel soaking, the brown waste water of a large amount of alkalinity, pollution green peel of walnut week will be generated
The soil on side and waters, cause environmental pollution.
The extraction separation of chemical composition and Components identification research make some progress in green peel of walnut at present, use gas phase
Method associated with Chromatography/Mass Spectrometry, which is identified in green peel of walnut, 39 kinds of volatile oil and 7 kinds of aliphatic acid；Each in green peel organises
The effect of polymer component is different, such as some ingredient extractions can be used for curing the disease, some ingredients can be applied to pesticide,
Pigment in green peel can be used as food additives etc..About the extracting method of pigment in green peel of walnut, in volume 13 of in August, 2001
The periodical of 4th phase《Chemical research and application》" Walnut picarp carries document disclosed in page 387 to 389 in walnut husk
Take and property tested " in, propose that with 60 DEG C of water be extractant, water is 1 with green peel mass ratio:5, it is green to dry 20g walnuts
Skin ground sample constant temperature impregnates 20 minutes, and immersion liquid is taken out in separation, then impregnates 20 toward the hot water constant temperature of 3 times of addition green peel quality in slag
Minute detaches taking-up immersion liquid again, and after the immersion liquid for merging secondary taking-up, heating concentration obtains brown pigment medicinal extract.This kind of method is applicable in
In laboratory in a small amount of green peel of walnut pigment extraction, it is extracted after green peel is ground, if industrialization extraction pigment, it is this
The cost of pre-treatment is higher, and when carrying out separation of solid and liquid to a large amount of leaching liquid, the green peel of grind into powder easily blocks
Filter membrane or chimney filter.
Invention content
The object of the present invention is to provide the insecticide containing walnut peel extract, the second purpose is to provide containing walnut blueness
The insecticide preparation method of bark extract.
The purpose of the present invention is achieved through the following technical solutions：
Insecticide containing walnut peel extract and preparation method thereof, includes the following steps：
（1）The green peel of walnut of collection is crushed；
（2）In step 1）Extraction solvent is added in the green peel of walnut, green peel is made to impregnate 1~2h in a solvent；
（3）Again by step 2）Green peel mixture after the immersion is heated to 50~65 DEG C of boilings and extracts 1~2h；
（4）By step 3）The cooking liquor is transferred to pressure filter press filtration, makes separation of solid and liquid and collects filtrate；
（5）By step 4）Auxiliary agent is added in the filtrate and stirs evenly the rear insecticide containing walnut peel extract to obtain the final product.
The step（1）In green peel of walnut be without rotten green peel of walnut；
The step（2）In Extraction solvent be at least one of water and ethyl alcohol；
The step（5）In auxiliary agent be at least one of glycerine and polyvinyl alcohol；
By document and patent retrieval, mentioned to doing insecticide in document and related patents with walnut peel extract, but
For yet there are no document report with the ingredient and preparation method of insecticide of the present invention, Related product also has no on the market
It arrives.
The present invention is provided for the prior art and product containing the insecticide of walnut peel extract and its preparation side
Method further enriches existing plant pesticide product, not only by green peel of walnut waste utilization, and is processed as a kind of high added value
Product, extend the industrial chain of petal resource.
The shortcoming of existing insecticide mainly has：More using the insecticide of chemicals, liquor residue amount is big, easy
It deposits in animal body, water and soil, ecology is polluted, pest is also easy to produce drug resistance, and poor selectivity generates larger wound to natural enemy
For evil to disappearing, cost is higher, and in spraying pesticide dispenser personnel are generated with certain stimulation and Health cost.
The main function mechanism of product of the present invention is that pest is generated to tag, kill and food refusal deterrent effect, and to crop
Protective effect is generated, the effect of so as to reach desinsection.
Product of the present invention is mainly reflected in compared with the advantage of existing product：
（1）Plant insecticide；
（2）Deinsectization effect is good, quick；
（3）Pest is not likely to produce drug resistance；
（4）It is nearly free from medicament residue；
（5）Hardly cause water and soil pollution；
（6）It is simple production process, easy to control；
（7）Product cost is relatively low.
The present invention will be described in detail based on the embodiment of the present invention below, but the present invention is not limited to this.
