Embodiment 1

[0012] Select fresh live adults of American cockroaches, soak them in an appropriate concentration of 75% ethanol until dead, remove the adult cockroaches, and discard the ethanol solution. The fished cockroaches are placed in an airtight container, soaked with 75% ethanol, sealed, and left to stand for 15 to 20 days, then the cockroach soaking solution is filtered, the filtrate is concentrated, and the ethanol is recovered to obtain an extract, which is stored in barrels for later use. Place the soaked cockroaches in an extraction tank and decoct 3 times: add 4 times the amount of water for the first time, filter after decocting for 2 hours; add 3 times the amount of water for the second time, decoct for 2 hours and then filter; Add 2 times the amount of water three times, decoct for 1.5 hours and then filter. Concentrate the decocted filtrate in vacuum at 60-70°C to a relative density of 1.3 to obtain an extract. Combine the above extracts, stir them evenly, spread them on ...

Embodiment 2

[0014] Select fresh living adults of American cockroaches, soak them in an appropriate concentration of 65% ethanol until dead, remove the adults of the cockroaches, and discard the ethanol solution. The fished cockroaches are placed in a closed container, soaked with 60% ethanol, sealed, and left to stand for 7 days, then the cockroach soaking solution is filtered, the filtrate is concentrated, and the ethanol is recovered to obtain an extract, which is stored in barrels for later use. Place the soaked cockroaches in an extraction tank and decoct twice: add 5 times the amount of water for the first time, decoct for 3 hours and then filter; add 3 times the amount of water for the second time, decoct for 2 hours and then filter. The decocted filtrate was concentrated in vacuum at 65°C to a relative density of 1.25 to obtain an extract. Combine the above extracts, stir evenly, add double the amount of starch, and use a one-step granulator to make granules to obtain the live adul...

Embodiment 3

[0016] Select fresh living adults of American cockroaches, soak them in an appropriate concentration of 83% ethanol until dead, remove the adults of the cockroaches, and discard the ethanol solution. The fished cockroaches are placed in an airtight container, soaked with 45% ethanol, sealed, and left to stand for 15 days, then the cockroaches soaked solution is filtered, the filtrate is concentrated, and the ethanol is recovered to obtain an extract, which is stored in barrels for later use. Place the soaked cockroaches in an extraction tank and decoct 3 times: add 6 times the amount of water for the first time, filter after decocting for 3 hours; add 3 times the amount of water for the second time, decoct for 2 hours and then filter; Add 2 times the amount of water three times, decoct for 1.5 hours and then filter. The decocted filtrate was concentrated in vacuum at 63°C to a relative density of 1.2 to obtain an extract. Combine the above extracts, stir evenly, add double th...

Abstract

The preparation process of alive adult roach extract includes the steps of: soaking alive roach in ethanol solution of 60-85 % concentration until death; soaking the roach in ethanol solution of 30-95 % concentration inside a sealed container, filtering the soaked liquid to obtain filtrate, concentrating the filtrate to obtain extractum while recovering ethanol; water extracting soaked roach via decoction for 2 or 3 times, filtering and vacuum concentration to obtain extractum; mixing the extractum obtained in the two steps; vacuum drying, and crushing to obtain powder. The product may be used in preparing some medicine for clinical application.

Description

Technical field [0001] The invention relates to a preparation method of an extract of living adult cockroaches. technical background [0002] Cockroaches are also known as cockroaches (see "Compendium of Materia Medica Supplements"). There are many records of cockroaches in historical documents, such as "Shen Nong's Materia Medica" records: "Taste salty, cold. Mainly blood stasis, cold and heat, broken accumulation, throat Closed, the internal cold has no children." [0003] Cockroaches have a variety of medicinal values. The secretory glands in the back of their pupae and adults can secrete a sticky protein secretion. The epidermis and ovary contain sclera, chitin, and digestive enzymes include protease, amylase, and lichenase. , maltase, etc. The muscles of the American cockroach are hydrolyzed to produce leucine, phenylalanine, valine, methionine, tyrosine, proline, alanine, glutamic acid, threonine, glycine, serine, Arginine, histidine, lysine, cystine, etc. Various ...
