Abstract
The present invention relates to a molluscacide powder made of Jatropha curcas seeds for killing snails, an extraction process thereof and an application thereof. The molluscacide powder made of Jatropha curcas seeds presents soil gray, sends out oil fragrance and is in a powdery state. The present invention can kill snails in pools, lakes or shallows by a method of dipping or spraying; besides, the powder has the advantages of convenient storage and transportation, no pollution on the environment, no toxin and harm to fish and favourable effect of killing snails.
Description
The present invention relates to plant extracts and extracting method, specifically a kind of molluscacide powder made of Jatropha curcas seed and extracting method and application that is exclusively used in unique intermediate host-oncomelania of elimination schistosoma.
Schistosomiasis is that blood fluke parasitizes the disease that causes in people or other mammal blood vessel.Schistosomiasis is distributed in more than 74 countries and regions, the world, and wherein 70% is popular in the torrid zone and subtropics country, infects population and reaches more than 300,000,000.What China was popular is Japanese schistosomiasis.12 provinces/urban district popular schistosomiasis in totally 391 counties (city, district) is arranged in China south, become the population of the side of body to reach more than 100,000,000.
People's schistosomiasis is a human body contact epidemic disease water (cercaria) and infecting, and wherein oncomelania is the unique intermediate host of blood fluke, and it has the peaceful amphibious characteristic of water, multiplies in natural environments such as soil humidity, weedy river, river, lakeshore, ditch, canal, the pool, rice field.Widely distributed, fertility is strong.According to statistics in the end of the year 1998, the existing oncomelania area of China reaches 34.7 hundred million m
2Killing oncomelania is control and blocking-up schistosomiasis propagation approach, prevents one of essential measure of schistosomiasis infection.
Niclosamidum is all used in countries in the world at present, and chemicals such as sodium pentachlorophenate are killed oncomelania, reduce its density, and reducing has spiral surface long-pending, and the control schistosomiasis infection is propagated, and eliminates schistosomiasis endemic.But because this type of chemicals toxicity is very big, contaminated environment, public hazards are serious, and microbial activity in the ambient soil and dominant microflora thereof are had the strong inhibition effect, and WHO announces in the recent period and contains dioxin " PCDDS " composition that causes people and animals' canceration in its composition.Banned use of penta sodium pentachlorophenate at present abroad.Niclosamidum is because of limiting the scope of application to the fish severe toxicity.
Before the present invention proposes, we had once applied for to Patent Office of the People's Republic of China that name was called the patent of invention of " a kind of numb maple seed extract and extracting method and application that is exclusively used in killing oncomelania " on December 16th, 1998, number of patent application is 98121712.5, and open this year.Though the described extract of this patent is killing oncomelania effectively,, be not easy in use store, transport, so it is unfavorable for the commercialization running because it is liquid.
The objective of the invention is in order to solve the deficiency that the above-mentioned background technology exists, propose a kind ofly can efficiently kill oncomelania, free from environmental pollution again, there are not public hazards, also be convenient to molluscacide powder made of Jatropha curcas seed and the extracting method storing, transport.
At this goal of the invention, the present invention adopts following technical scheme: a kind of molluscacide powder made of Jatropha curcas seed, its special character are that this pulvis is to extract from numb maple seed, and its extracting method in turn includes the following steps:
1) cleans: numb maple seed water is cleaned up
2) oven dry: above-mentioned raw materials is dried to water content≤10% under 50 ℃-60 ℃ temperature
3) deoil: oil content is removed in squeezing on press apparatus, and making numb maple seed bits oil content is 8-15%
4) pulverize: bits are crushed to smalls, cross 60 mesh sieves and promptly be the field gray salted cake fried in sesame oil Powdered finished product of distinguishing the flavor of.
Fiber crops maple seeds (Jatropho curcas) are the seeds of numb maple, and this plant belongs to Euphorbiaceae, shrub or dungarunga, and growth is vigorous in the torrid zone.In Yunnan of China, there are a large amount of cultivations or seminatural numb maple in area such as Guizhou, Guangdong, Guangxi.
Numb maple seed extract of the present invention be from numb maple seed, extract be field gray salted cake fried in sesame oil flavor powder, it has very strong killing action to oncomelania.Its mechanism is the information channel that numb maple seed extract can disturb the oncomelania cell, and promptly activator protein enzyme e causes oncomelania physiology Ca ion concentration to descend.Because numb maple seed extract is stable, can not degraded fast, thereby its can sustained activation and cause oncomelania death.See Appendix table 1 in 1, table 2, table 3.
Another goal of the invention of the present invention is to provide the application of molluscacide powder made of Jatropha curcas seed.I.e. this pulvis application aspect the oncomelania in eliminating the Nature preferably is applied to eliminate oncomelania in the Nature to soak behind method extremely or the water dissolved dilution with spray method.
Molluscacide powder made of Jatropha curcas seed uses easily, and according to the oncomelania ecosystem characterization, what be chosen in every year carries out the spiral shell that goes out in two seasons of spring and autumn, and its concrete grammar is:
1, soaks method extremely: be applicable to the pond that to control water level, Luo Chu arranged, directly place water to soak in an amount of pulvis and kill spiral shell as irrigation canals and ditches, small reservoir, rice field etc.
2, spraying: be applicable to ground such as river, river, lake, continent, the beach spiral shell that goes out, earlier that an amount of pulvis is soluble in water, it is best that concentration is controlled at 8mg/L-200mg/L, carries out spraying molluscicide then.If can spray behind the first uproot weeds during use, effect can be better.
The on-the-spot molluscicidal effect of the molluscacide powder made of Jatropha curcas seed of the various dose table 4 in 1 of seeing Appendix.
In sum, utilize the molluscacide powder made of Jatropha curcas seed killing oncomelania, have following advantage:
1, aboundresources: numb maple (Jatropho) is vigorous in the growth of torrid areas, the whole world, particularly rural area, ground, roadside, shrub edges such as Yunnan Province of China, Guangxi, Guizhou, Guangdong are seen everywhere, and growth is fast, the output height, doing kind of a clay test in Hubei province, is successful.If in an organized way cultivate and fully utilize, not only can bring about a prosperous economy, and can keep local water and soil well.
2, production is easy: the extraction process of molluscacide powder made of Jatropha curcas seed is easy, and its equipment and operation all do not have specific (special) requirements.
3, easy to use: environmentally safe, to fish, person poultry harmless, sn ail control effect is continual and steady.
4, with low cost: its integrated cost is lower than the chemistry spiral shell preparation that goes out.
Embodiment:
The concrete extracting method of molluscacide powder made of Jatropha curcas seed in turn includes the following steps:
1) cleans: numb maple seed water is cleaned up;
2) oven dry: above-mentioned raw materials dried under 50 ℃-60 ℃ temperature to water content≤10% get final product;
3) deoil: squeeze on common squeezer, remove the oil content in the numb maple seed, making the numb maple seed bits oil content in squeezing back is 8-15%, so both can make the powder that makes can not produce bonding, can make again and contain enough spiral shell effective ingredients of going out in the powder;
4) pulverize: numb maple seed bits are crushed to smalls, cross 60 mesh sieves and get final product.
It is Powdered that the molluscacide powder made of Jatropha curcas seed that makes at last is field gray, and it is convenient to store, transports, is fit to the commercialization running.
Annex 1: plant molluscicide JCS kills the test report of spiral shell test (retrial).
Annex 2: plant molluscicide JCS fish acute toxicity test.
