Extracting method for kuh-seng disinfection composition and sanitizer containing the kuh-seng disinfection composition

Abstract

The invention belongs to the field of disinfectants, and in particular relates to a method for extracting a sophora flavescens bactericidal component, as well as a disinfectant prepared from sophora flavescens extract containing the sophora flavescens bactericidal component. The extraction method comprises the following steps: after dried ground sophora flavescens is added to acetone and soaked, acetone solvent for soaking the sophora flavescens is heated and refluxed; sophora flavescens dregs are filtered and removed, and then a filtrate is collected; the obtained sophora flavescens dregs are washed with the acetone, so as to obtain a washing solution; the washing solution is combined with the obtained filtrate, so as to obtain a primary filtrate; the primary filtrate is filtered by use of an ultrafiltration device and a film with the interception molecular weight between 5,000 and 10,000, so as to obtain a secondary filtrate; the obtained secondary filtrate is put into a rotary evaporator to steam off the acetone solvent, so as to obtain the sophora flavescens extract; and the sophora flavescens extract contains the effective bactericidal component of the sophora flavescens. The disinfectant which is prepared by adding acetone and alkylphenol polyoxyethylene ether as an emulsifier in certain proportion to the sophora flavescens extract contains the sophora flavescens bactericidal component and has good sterilization effects.

Description

technical field [0001] The invention belongs to the field of disinfectants, and in particular relates to a method for extracting bactericidal components of Sophora flavescens, and a disinfectant prepared from extracted Sophora flavescens extract containing bactericidal components of Sophora flavescens. technical background [0002] Among the fungicides used at this stage, chemical drugs account for a considerable proportion, and the long-term use of chemical drugs has brought problems such as chemical drug residues and environmental pollution to the environment. Under the situation of increasing awareness of global environmental protection, chemical drugs are facing serious challenges, and drugs derived from natural sources are becoming a hot spot in drug research and development. Drugs derived from natural sources include drugs from plant sources, microbial sources and mineral sources, most of which are derived from plants. Most of the secondary metabolites in plants, such...

Problems solved by technology

However, through extraction by heat reflux method, the extract contains impurities (ineffective components) with a relative molecular mass greater than tens of thousands, and the existence of this part of impurities destroys the effect of active components.
