Abstract
The invention belongs to the field of disinfectants, in particular to 13,14-dihydroxyl matrine bactericide and application thereof. The main active ingredient of the 13,14-dihydroxyl matrine bactericide is 13,14-dihydroxyl matrine. The 13,14-dihydroxyl matrine belongs to the derivative of matrine, is a plant-derived bactericide, does not contain any harmful chemical components, has low toxicity to people and livestock, does not have residues and does not pollute the environment. In a sterilizing test, the sterilizing ratio of the bactericide prepared from the 13,14-dihydroxyl matrine on escherichia coli and golden staphylococcus is over 99.9 percent.
Description
Technical field
The invention belongs to the disinfectant field, particularly 13,14-dihydroxy matrine antibacterial and uses thereof.
Technical background
In the antibacterial that uses, chemicals occupies sizable ratio at present, and the life-time service of chemicals has brought problems such as chemicals is residual, environmental pollution to environment.Under the enhanced situation of global environmental consciousness, chemicals is being faced with serious challenge, and plant-derived medicine is just becoming the focus of drug development research.At present, the research and development of plant-derived medicine mainly is divided into four levels: (1) seeks the reactive compound of medicine from native compound, the mixture of the monomer of reactive compound or reactive compound is directly used in is processed into the dissipation medicine; (2) carry out reasonable compatibility with the active constituents of medicine in the different plants (perhaps monomer); (3) the synthetic plant source medicinal compounds of manual simulation; (4) with the plant source active component be the effective ingredient of first guide structure screening of medicaments.The domestic research and development of carrying out at present mainly is in above-mentioned (1) and (2) level, promptly rest in the direct extraction of plant source disinfectant, as the method for preparing vegetable insecticide with Radix Sophorae Flavescentis extract and products thereof (CN 1148937), berberine matrine sterilization and disinsection water preparation (CN 1233235C).Level to the research and development of plant-derived disinfectant is not deep enough, mainly is the active ingredient definite proportion difficulty really of medicine.Different plants, and the effective ingredient difference of the different parts of plant, same kind of plant contains multiple different medicine active ingredient and brings very big difficulty to synthetic, and this also is the synthetic less major reason of plant-derived disinfectant of present manual simulation.How studying on the basis existing, developing novel plant source property antibacterial is the key issue that will solve at present.
13,14-dihydroxy matrine belongs to the derivant of matrine, can adopt semisynthetic method to obtain, and has better water solubility, and bactericidal effect is good.With 13,14-dihydroxy matrine is that the antibacterial document of effective ingredient is not reported as yet.
Summary of the invention
The object of the present invention is to provide a kind of bactericidal effect good, do not have 13 of an environmental pollution, 14-dihydroxy matrine antibacterial.
An also purpose of the present invention is to provide 13, the purposes of 14-dihydroxy matrine antibacterial.
Of the present invention 13,14-dihydroxy matrine antibacterial, main effective ingredient is 13,14-dihydroxy matrine; This 13, the composition and the content of 14-dihydroxy matrine antibacterial are preferably 13 of 2～2.5wt%, the water of 14-dihydroxy matrine and surplus.
Among the present invention 13,14-dihydroxy matrine belongs to the derivant of matrine, 13, the preparation of 14-dihydroxy matrine is to be raw material with the sophocarpine, the employing semisynthesis is synthetic, synthetic method can be with reference to the structural modification and transformation research (Duan Zhenhua, Shaanxi Normal University's Master's thesis: 2007,5) of Radix Sophorae Flavescentis alkaloid.
Of the present invention 13, the preparation method of 14-dihydroxy matrine antibacterial is: get 13,14-dihydroxy matrine is dissolved in and obtains antibacterial in the water, preferably makes 13, and 14-dihydroxy matrine accounts for 2～2.5wt% of antibacterial.
Described 13, the molecular structural formula of 14-dihydroxy matrine is:
Beneficial effect of the present invention and advantage: 13,14-dihydroxy matrine belongs to the derivant of matrine, is plant-derived antibacterial, does not contain any harmful chemical analysis, to the people, animal low toxicity, does not have residual, free from environmental pollution.In bactericidal assay, with 13, the antibacterial that 14-dihydroxy matrine is mixed with all reaches more than 99.9% the sterilizing rate of escherichia coli and golden staphylococci, is respond well antibacterial.
