Embodiment 1

[0025] Example 1: Preparation of Tiannv Magnolia Extract by Steam Distillation

[0026] Take 50kg of Magnolia leaves, crush them to 20 mesh, put them in 4 steam distillation reaction kettles in series, disperse them evenly, add a net cover, feed water vapor, open the condenser, react for 1 hour, collect the extract, separate oil and water , to obtain 12.8kg of Tiannv Magnolia extract. Concentrate again to a certain ratio to obtain the extract of Magnolia magnolia used in this experiment.

Embodiment 2

[0027] Embodiment 2: Preparation of Tiannv Magnolia Extract by Water Extraction

[0028] Take 1 kg of Magnolia chinensis leaves and crush them to 40 mesh, add distilled water according to the mass-volume solid-liquid ratio of 1:3, and at the same time add 2wt% cellulase based on the total mass of Magnolia chinensis leaves, extract at 50-60°C for 2 hours, filter, Obtain the filtrate, add 0.5wt% based on the total mass of the filtrate and a compound decolorizing agent based on 0.5wt% of the total mass of the filtrate and a mass compounding ratio of 1:1 and activated clay for decolorization, and pass through a ceramic membrane to obtain 2.4 kg of Magnolia radiata extract.

Embodiment 3

[0029] Embodiment 3: Alcoholic extraction method prepares Magnolia Magnolia extract

[0030] Take 1 kg of magnolia leaves and crush them to 40 mesh, add 75% ethanol by volume according to the mass volume solid-liquid ratio of 1:3, stir at 70°C, condense and reflux, extract for 2 hours, and filter to obtain the filtrate. Use a rotary evaporator to remove the ethanol in the filtrate until there is no alcohol smell in the solution, and add water to replace the evaporated ethanol. Add a compound decolorizing agent based on 0.5wt% of the total mass of the filtrate and a mass compounding ratio of 1:1 of activated carbon and activated clay for decolorization, remove the decolorizing agent through a ceramic membrane, and obtain 1.1-3.3 kg of Magnolia magnolia extract.

Abstract

The invention discloses application of a magnolia sieboldii extracting solution as a bacteriostatic agent. The magnolia sieboldii extracting solution is prepared through a steam distillation method or a water extraction method or an alcohol extraction method, and is completed in one step, technological operation is simple, and the prepared magnolia sieboldii extracting solution contains no organic solvent, is free of hazardous substance residues and small in irritation, and meets green and natural concept. The antibacterial effect of the magnolia sieboldii extracting solution is tested through fungus inhibiting tests, bacterium circle inhibiting experiment tests and antiseptic challenge experiment tests, and it is proved that the magnolia sieboldii extracting solution can remarkably achieve the antibacterial effect of inhibiting mould, saccharomycetes and other fungi. The application range of the magnolia sieboldii extracting solution on the market is greatly widened. The magnolia sieboldii extracting solution is applied to cosmetics, food and healthcare products as the bacteriostatic agent, the adding amount is small, and the antibacterial effect of inhibiting mould, saccharomycetes and other fungi can be achieved on the cosmetics, food and healthcare products.

Description

technical field [0001] The present invention relates to a new application of the extract of Magnolia tiannv, in particular to the use of the extract of Magnolia tiannv as a bacteriostatic agent. Background technique [0002] With the improvement of living standards, more and more people begin to pay attention to the safety of preservatives in cosmetics, food and health products. Traditional preservatives are mostly chemically synthesized, such as sodium benzoate, formalin, paraben, nitric acid Salt, etc., which have some risks of carcinogenicity and skin irritation in cosmetics, food, and health products. [0003] In recent years, on the one hand, there have been more cosmetics without paraben esters, most of which use phenoxyethanol or glycols as antibacterial ingredients, but their disadvantages lie in the continuous use of polyol antiseptic systems, and excessive skin contact with polyols, As a result of the accumulation of polyols, the skin will have a sense of heat and...
