Abstract
A biodeactivating agent for oncomelania and schistosome is prepared from the Chinese medicinal materials such as drug sweetflag, Paris polyphylla and oroxylum indicum through alcohol extraction, and features 100% of decactivating rate, abundant raw material, no environmental pollution, and low cost.
Description
Oncomelania and blood fluke are born among the water environment now, and its harm is well-known, adopt the method for throwing in chemical agent in the waters to kill oncomelania and cercaria now usually.The chemical killing agent of existing employing mostly with penta sodium pentachlorophenate and or niclosamidum as primary raw material, according to the result of application test, use 10g/m
2The phenol sodium spiral shell that goes out, 3,7,15 days lethality is respectively 71.7%, 87.9% and 95.4%, all can not reach absolutely.Though the sn ail control effect of niclosamidum is high slightly, its side effect is bigger, and WHO bans use of.Except that above-mentioned two kinds of chemical agents, also have employing such as with farm antibioticss such as light gray streptomycins as the oncomelania agent for killing, but generally speaking, above-mentioned medicament more or less all exists the certain environment influence, and in general production cost is higher, manufacturing process is comparatively complicated, and the effect of main is these inactivators is all undesirable, and environment is produced certain negative influence.
Therefore, the inventor has proposed a kind of killing oncomelania and bilharzial bio-deactivator of being exclusively used at the defective of existing chemical molluscacide and farm antibiotics, it has not only improved above-mentioned all kinds of reagent cost height, inefficient defective, and the raw material source is wide, technology is simple, has non-harmful characteristics especially.
The solution of the present invention is to be primary raw material with the Chinese herbal medicine calamus, is equipped with the blood rattan, paris polyphylla, and assistant agents such as tarragon and realgar utilize Chinese herbal medicine traditional fabrication method to extract former medicine.As long as being sprinkled in the waters after the former medicine dilution, (72-96 hour) can all kill oncomelania and cercaria in a short time during use.
Detailed description of the present invention is that it is mainly filled a prescription and is:
Paris polyphylla, 10-20 part;
The blood rattan, 1-10 part;
Add calamus to 100 part.
Production technology is, with the calamus (rhizoma calami and grass-leaved sweetflag) of gathering, blood rattan and paris polyphylla (blood rattan and paris polyphylla must be steeped with rice washing water and be given processing as sterilization in 24 hours) are dried, and make its water content be lower than 18%, soak with organic solvent again.When summer, daily mean temperature was about 28 ℃, soak time was 7 days; When spring and autumn, the sky daily mean temperature was 22 ℃, soak time was 25 days.Then the mixed liquor after soaking is filtered, removes slag, reclaim solvent with the way of distillation again, remove moisture content after, can obtain yield is the bio-deactivator crude oil of 2-3% (weight ratio).Crude oil is light green, and dense fragranced is arranged, and people and animals are comprised that aquatile is nontoxic, and is nuisanceless to environment, and its filter residue can be used as a kind of efficient organic fertilizer and returns the field.
Above-mentioned prescription is mainly used in kills oncomelania and blood fluke and cercaria thereof, but also can add an amount of tarragon and realgar in above-mentioned prescription, then can improve and kill oncomelania efficient.When adding tarragon and realgar, tarragon and realgar are dried to water content be lower than 18% equally, reinstate organic solvent with calamus, blood rattan, paris polyphylla one then and quench and get.
Above-mentioned can be alcohols as the organic solvent of getting of quenching, all organic solvents that are suitable for such as ethers, but concentration is that cost is the most cheap greater than 95% ethanol, best active solvent without any side effects.
Utilize oncomelania of the present invention, blood fluke bio-deactivator to eliminate the oncomelania in the water, when blood fluke and cercaria thereof, must estimate the volume of water body earlier, in the ratio of 15-25PPM, after the dilution of inactivator crude oil, the method with dot matrix is spread on the water surface more then.
Report that according to the application test that prevention and cure of schistosomiasis stations, ground such as Hunan Province parasite research institute, Changde, Hanshou, Yuanjiang are done about the 72-96 after spreading pesticides hour, the inactivation ratio of oncomelania, blood fluke and cercaria thereof can reach 100%.
Oncomelania, the blood fluke life inactivator that the present invention proposes has the raw material source for killing oncomelania blood sucker and cercaria thereof abundant; production cost is low, and is easy to use, the characteristics that eradicative rate is high; for the source of eliminating schistosomiasis, the protection mankind have very big meaning.
Claims (2)
1, a kind of killing oncomelania, blood fluke bio-deactivator of being exclusively used in, the Chinese herbal medicines such as a calamus, paris polyphylla and blood rattan that are characterized as of the present invention dry the back and get crude oil by certain weight ratio with alcohol-pickled quenching, and it is combined as:
Paris polyphylla, 10-20 part;
The blood rattan, 1-10 part;
