Embodiment 1

[0025] Example 1: Preparation of Magnolia sylvestris extract by steam distillation

[0026] Take 50kg of Magnolia leaves, crush them to 20 meshes, put them in 4 steam distillation reactors in series, disperse them evenly, add a mesh cover, pass in steam, open the condenser, react for 1h, collect the extract, separate the oil and water , Get 12.8kg of Magnolia sylvestris extract. Concentrate a certain proportion to obtain the Magnolia grandiflora extract used in this experiment.

Embodiment 2

[0027] Example 2: Preparation of Magnolia sylvestris extract by water extraction method

[0028] Take 1kg of Magnolia sylvestris leaves and crush them to 40 meshes, add distilled water according to the mass-volume ratio of material to liquid at 1:3, and add 2wt% cellulase based on the total mass of sylvestris Magnolias leaves. Extract at 50-60℃ for 2h and filter. Obtain the filtrate, add 0.5wt% based on the total mass of the filtrate and a compound decoloring agent of activated carbon and activated clay with a mass compound ratio of 1:1 for decolorization, and pass through a ceramic membrane to obtain 2.4 kg of Magnolia sylvestris extract.

Embodiment 3

[0029] Example 3: Preparation of Magnolia sylvestris extract by alcohol extraction

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

[0031] Antibacterial effect test

[0032] 1.1 Antibacterial (fungus) test

[0033] Take the Magnolia sylvestris extract prepared in accordance with Example 1 in 2012, 2014, and 2015, and detect the microorganisms in the three sylves...

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 use of Magnolia sylvestris extract, in particular to the use of the extract of Magnolia sylvestris as a bacteriostatic agent. Background technique [0002] With the improvement of living standards, more and more people are paying attention to the safety of preservatives in cosmetics, food, and health products. Traditional preservatives are mostly chemically synthesized, such as sodium benzoate, formalin, paraben, and nitric acid. Salt, etc., in cosmetics, food, and health products, there are some risks of carcinogenesis and skin irritation. [0003] In recent years, on the one hand, there have been more paraben-free cosmetics, and most of them use phenoxyethanol or glycols as antibacterial ingredients. However, the disadvantage is that the continuous use of polyol preservative systems makes skin contact with too much polyol. As a result of the accumulation of polyols, the skin will have a feeling of heat and irritation,...
