Background technology:
Grub also known as hen worm, grub, one's old mother worm, worm etc. when white, build is loose, common name scarab beetle or cockchafer after adult
Son, composition are mainly made of fat, protein.
For insect as the more huge species of population quantity type on the earth, insect possesses unique and larger animal not
The same immunologic mechanism carries out immune defense by secreting the various immune substances including antibacterial peptide, therefore passes through induction
Form promote Insect transformation secret out of all kinds of antibacterial peptides, by its extraction and application, curative effect more preferable than conventional medicament can be obtained
Product.
Antibacterial peptide is small molecule peptides active material, is the small peptide with antibacterial activity, is present in different kind organism body
It is interior.Antibacterial peptide has certain resistance to microorganism and parasite, but is influenced on organism itself smaller or without influence, and arrives mesh
Before until not yet find that antibacterial peptide can make microorganism and parasite generate resistance, be that one kind can be used for substituting resistance getting worse
Antibiotic product.
About the extraction application of grub antibacterial peptide, report is less, and traditional extraction process is that directly mashing is obtained by filtration, pure
Degree and content are insufficient.
Invention content:
The method that the object of the present invention is to provide a kind of to extract antibacterial peptide from grub, to solve the above technical problems.
The present invention can keep it is active under the premise of high efficiency extraction grub antibacterial peptide.
To achieve the above object, the present invention provides following scheme:
The present invention provides a kind of method for extracting antibacterial peptide from grub, includes the following steps:
