Method for preparing phthisic adjuvant with extractum of Periplaneta americana

The invention relates to the field of medical technology, and especially relates to a method for preparing a phthisic adjuvant with extractum of Periplaneta Americana. The invention provides the method for preparing a phthisic adjuvant with extractum of Periplaneta Americana, wherein the method comprises the following steps of: A, smashing; B, soaking; C, extracting; D, first concentration; E, degreasing; and F, second concentration. With the method, a lot of proteins in the Periplaneta americana can be removed effectively, the grease removal rate is high, and the oil content of the obtained extract is only 0.30 counted by A(absorbance) / W(Weight). By the alcohol with concentration of 90%-95%, the adjuvant can be prevented from spoilage, the preservation time is prolonged, and the yield of active ingredients is improved. The content of the active ingredients is up to 13%-22%, the cure rate of the prepared medicine to the phthisis is up to 45%, and the total effective rate can be 85%. Hydrolysis of active substances (in the extract) for adjunctive treatment to the phthisis is prevented, and the therapeutic effect of the adjuvant is improved. The production cost is lowered, and the production efficiency is improved.

Method for extracting medicinal material from Periplaneta americana

The invention provides a method for extracting medicinal substances from Periplaneta American Linn, which comprises the following steps: A, alcohol extraction: killing and soaking larvae in alcohol; freezing the larvae at a low temperature; cracking shells, carrying out coarse-sizing, placing in an extractor and soaking in alcohol; thermal-reflux alcohol-extracting, recovering the drug liquid, placing in a separator and carrying out the oil-water separation; filtering and concentrating the separated drug liquid; discharging and cooling the drug liquid to obtain the medicinal substances; and B, water extraction: pouring the materials of alcohol extraction into distilled water; carrying out heating extraction; recovering and placing the drug liquid in the separator and carrying out the oil-water separation; and filtering and concentrating to obtain the medicinal substances. Compared with the prior art, the method of the invention improves the extraction yield and increases the total content of amino acid as well as the contents of polypeptide, protein, chitin, chitosan and the like in the extracted medicinal substances, and is particularly characterized in that the unpleasant odor is eliminated by low-temperature freezing before the extraction, therefore, the extracted medicinal substances have almost no unpleasant odor from the original extract while more bioactive substances are preserved.

DsRNA designed based on Orco gene of periplaneta americana, and coding gene, preparation method and application thereof

ActiveCN110468131AEffective control of matingEffective control of reproductionBiocideAnimal repellantsMatingNucleotide
The invention discloses dsRNA designed based on an Orco gene of periplaneta americana, and a coding gene, a preparation method and an application thereof. The dsRNA is a double-stranded RNA composed of a nucleotide sequence shown in SEQ ID NO.1 and used as a positive-sense strand and a nucleotide sequence reversely complementary to the nucleotide sequence shown in SEQ ID NO.1 and used as an antisense strand. The dsRNA can be widely applied in preparation of products for preventing and treating the periplaneta americana, interfering the chemical communication of the periplaneta americana or controlling the mating and reproduction of adult periplaneta americana, or preventing and controlling the periplaneta americana and other insects having the same gene target sequence. By blocking key genes of an olfactory system of periplaneta americana, the induction effect of sex pheromone to male insects is inhibited, mating and reproduction of the periplaneta americana can be effectively controlled, and a new technology and strategy are provided for prevention and control of the periplaneta americana.

Artificial propagation method of American periplaneta

ActiveCN101438693AThe method of artificial reproduction is simpleArtificial propagation method is scientifically feasibleAnimal husbandryPeriplanetaHatchery
The invention discloses an artificial propagation method for periplaneta americana. The method comprises the following steps: a sack, an incubator, a breeder box and an egg tray are sealed and fumigated for one hour after being evenly mixed with disinfecting solution; the temperature in the incubator is controlled between 29 DEG C and 33 DEG C through an automatic temperature and humidity control device, the relative humidity is controlled between 80 percent and 85 percent, and the inside of the incubator is well ventilated; a layer of sack is arranged at the bottom part of the breeder box or a hatching bamboo sieve, a layer of ootheca with a thickness of 1 cm to 3 cm is placed on the sack, a layer of egg tray is transversely placed on the ootheca, and a layer of sack is also covered on the egg tray; the breeder box or the hatching bamboo sieve is placed on a partition board with a hole in the incubator or on a hatchery rack of a hatching house; and when 10 to 30 larvae are generated in each egg tray, the egg trays in which the larvae are hidden are gently transferred to breeding chips, and the larvae hidden in the egg trays naturally enter in the chips to grow. The method can overcome the problems of low hatchability and long hatching period, and is suitable for the large-scale artificial propagation of the periplaneta americana.
