Embodiment Construction

[0018] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0019] Crush yellow vine, basil and flavescens into 20-40 mesh coarse powder respectively. The plant Huangteng uses 10% ethanol water solvent system, Sophora flavescens uses 50% ethanol water solvent system, the extraction solvent ratio is 10 times the quality of the crude drug, extracts in an external circulation extraction tank at 60 °C for 2 hours, and prepares each extract by conventional filtration and flocculation methods. liquid. Plant basil was prepared by steam distillation to obtain its oil phase.

[0020] Each of the plant extracts obtained in the above-mentioned steps uses basil essential oil as the oil phase, the extract of Huangteng vine and the extract of Sophora flavescens as the water phase, Tween-20 as the surfactant, and propylene glycol as the co-surfactant. The components are as follows: Proportion weigh...

Abstract

The invention discloses a preparation method for a natural preservative micro-emulsion preparation. The preparation method comprises the following steps: (1) extracting daemonorops margaritae by a 10% ethanol aqueous solution, and preparing to obtain an extract; (2) obtaining an oil phase part of basil by virtue of a steam distillation method; (3) extracting sophora flavescens by a 50% ethyl alcohol aqueous agent system; and (4) with basil essential oil as an oil phase, the daemonorops margaritae extract and the sophora flavescens extract as water phases, tween-20 as a surfactant, and propylene glycol as a cosurfactant, preparing in a certain ratio to obtain the oil-in-water micro-emulsion preparation. Due to the adoption of the preparation method disclosed by the invention, the extract has a high active ingredient content, a good antibacterial effect, as well as efficient, safe, stable, non-toxic, antibacterial and healthcare effects. The natural preservative micro-emulsion preparation can be widely used for preservative applications in the fields of foods, medicines, cosmetics, biochemicals and the like.

Description

technical field [0001] The present invention relates to a kind of preparation method of microemulsion preparation, more specifically, relate to a kind of preparation method of natural antiseptic microemulsion preparation. Background technique [0002] The active ingredients in each functional plant have different characteristics such as polarity and solubility. According to the conventional extraction method of compound medicinal materials, the efficacy may be weakened, and the effect of the plant cannot be maximized, which violates our provision. The original intention of the plant compound. Therefore, according to the different characteristics of the active ingredients of each plant in the natural preservative compound, we design reasonable and effective extraction and purification processes, and then configure the natural preservative formula in a certain proportion. [0003] Microemulsion is an isotropic, transparent, thermodynamically stable system with a particle size...
