Embodiment 1

[0020] Carry out the extraction of American cockroach extract according to the following steps:

[0021] A alcohol extraction:

[0022] 1) Inactivate the raw material cockroaches with 70°C hot water;

[0023] 2) After drying at 70°C, coarsely pulverize and sieve;

[0024] 3) Put it in a container, soak the surface of the raw material in 80-degree alcohol for 48 hours;

[0025] 4) Put the above-mentioned treated matter into a multi-functional extractor, add 3 times of 80% alcohol, heat reflux extraction for 7 hours, and start to recover alcohol. The temperature of the whole process of alcohol extraction is 65-75°C;

[0026] 5) Recover the medicinal liquid and put it in the separator for oil-water separation;

[0027] 6) The separated medicinal liquid is filtered through a microporous filter;

[0028] 7) Put the filtrate in a vacuum concentrator to concentrate it to a concentration of 1:1.3, release it and cool it to obtain an extract, and the temperature during the concentr...

Abstract

The medicinal American giant roach extractum preparing process includes alcohol extraction process and water extraction process. The alcohol extraction process includes hot water killing of roach, drying, crushing, sieving; alcohol soaking for 40-50 hr; alcohol reflux extraction in a multifunctional extractor; recovering alcohol; recovering medicine liquid via oil-water separation; and filtering and concentrating medicine liquid to obtain extractum. The water extraction process includes extraction of the material after recovering alcohol in alcohol extraction process in distilled water; recovering medicine liquid and oil-water separation; filtering and concentrating medicinal liquid; and cooling to obtain extractum. The said preparing process has high yield, and the product has total amino acid content up to 50.4 %.

Description

technical field [0001] The invention relates to a process for extracting medicinal extract of Periplaneta americana. Background technique [0002] The American cockroach (Periplaneta American Linn) is an insect. The medicinal solution extracted from Periplaneta americana can be used in skin care products, medicines, health care products, etc. It has the effect of promoting tissue growth and healing and anti-oxidation. It can sober up and protect the liver, nourish the stomach, promote the healing of gastric ulcer and duodenal ulcer, and promote inflammation. It can heal ulcers and has adjuvant therapeutic effect on tumors, deficiency syndrome and tuberculosis. The method used in the existing Periplaneta americana extraction process is the traditional alcohol extraction method, most of the water-soluble amino acids have not been extracted, the extraction rate is only 8.7-10.3%, and the total amino acid content of the product is only 29.8%. Contents of the invention [000...
