according to the mass percentage composition of the table 1, the bacteriostat, the synergistic agent and the solvent are uniformly stirred and mixed and dissolved, and the plant extract composite bacteriostat with each proportion can be obtained.
Table 1. plant extract composite bacteriostatic agent in each proportion.
Test example 1. minimum inhibitory concentration test.
1. Experimental reagent: nutrient broth (Guangdong Huaqiao microbiological science, Inc., 022010); sterilizing fructus Hordei Germinatus extract decoction (027130, Kyoto cyclochei microorganism technology Co., Ltd.) in deionized water; 0.85% physiological saline, sterilizing and using.
2. Experimental materials: the bacteriostatic agents are shown in the table 1.
3. The species and source of the experimental strain: escherichia coli ATCC25922, Pseudomonas aeruginosa ATCC9027, Staphylococcus aureus ATCC6526, Pseudomonas putida GDMCC NO.60411, Aspergillus niger ATCCL6404 and Candida albicans ATCCL0231 which are all from Guangdong province microorganism strain preservation center; burkholderia cepacia CGMCC No.5384, which is from the China general microbiological culture Collection center of the Committee for culture Collection of microorganisms.
4. And (4) preparing a bacterial suspension.
TABLE 2 proportion of McLeod turbiditubes
The turbidimetric vials prepared according to the proportions in table 2 were used as standard bacterial suspension controls. Respectively adding sterile 0.85% of normal saline (0.85% of NaCl) into each strain slant, respectively washing out a certain amount of bacteria, then adding the washed bacteria into a sterile test tube with the same diameter (size) as that of the McLeod's turbidimetric standard tube, respectively adding sterile 0.85% of normal saline (0.85% of NaCl) for dilution until the concentration is the same as that of the McLeod's turbidimetric standard tube, taking the diluted bacteria as bacterial suspension, and finally diluting each bacterial suspension by 100 times for later use.
5. And (4) determining the minimum inhibitory concentration.
Taking 12 sterile test tubes, sequentially marking, transferring 3000 μ L of liquid culture medium (nutrient broth for bacteria, and wort extract for fungi) into the sterile test tubes with pipette gun, and sequentially adding 3000 μ L of prepared liquid culture medium C into the 12 test tubes 1 ，C 2 ，C 3 ，C 4 … … sample (C) 1 ，C 2 ，C 3 ，C 4 … … concentrations were set according to each example test range and gradient decreased), 3 replicates per concentration; in addition, with 1 control sample, 3000. mu.L of liquid medium and 3000. mu.L of 0.85% physiological saline were added, and finally, 300. mu.L of each bacterial suspension was added to the test tube; plugging the inoculated test tube with a plug, and placing the test tube inoculated with the microorganism in a shaking table at 30 ℃ for culturing for 48 hours; taking out the culture medium at 24h and 48h, shaking the test tube, and if sediment is produced at the bottom or the solution is turbid, the strain cannot be inhibited from growing at the concentration; on the other hand, the concentration is such that the growth of the species is inhibited (for example, in E.coli inoculated tubes, the concentration is C 1 ，C 2 ，C 3 The test tube of (A) produced no precipitate and the solution was relatively clear at a concentration of C 4 The bottom of the tube is precipitated or the solution is cloudy, and the minimum concentration of the sample for inhibiting Escherichia coli is C 3 )。

Then dividing the test sample into a blank control group, a model control group and a sample group, wherein each group is provided with 6 complex holes, 50 mu L of corresponding samples to be tested are respectively added into the test sample group, 50 mu L of DMEM culture medium is respectively added into the blank control group and the model control group, the test sample group and the model control group are placed in an incubator to be pre-incubated, and after 1h, except the blank control group, cells of each group are placed under a 15W ultraviolet lamp and irradiated for 30s to induce P815 cells to generate anaphylactic reaction and release histamine. Then put 5% CO 2 The culture box is used for culturing for 24 hours. After 24h, 200. mu.L of the culture medium was removed for derivatization of histamine, and saturated NaHCO was added in sequence 3 The solution (300. mu.L) and dansyl chloride (300. mu.L) at 20mg/mL were reacted at room temperature for 1 hour, then 20% ammonia-acetonitrile solution (100. mu.L) was added to terminate the reaction, and after 1 hour, 100. mu.L of acetonitrile solution was added, and HPLC analysis was performed after filtration through a membrane.
4. Result judgment
Preparing a solution with the concentration of 1,5, 10, 20 and 50ppm by using a histamine standard sample, filtering the solution by using a filter membrane, performing HPLC analysis, drawing a standard curve by using the concentration of the histamine standard sample as a horizontal coordinate and using a corresponding chromatographic peak area as a vertical coordinate, and calculating the concentration value of each sample according to the standard curve.
Table 4. test results of the inhibition effect experiment of the plant extract composite bacteriostatic agent on histamine release amount.
As shown in Table 4, it can be seen from comparative examples 3 to 11 and comparative examples 1 to 6 that the peony root bark extract and the Schisandra chinensis extract have a significant inhibitory effect on histamine release amount; due to the addition of the schisandra chinensis extract and the saccharomyces cerevisiae fermentation product extract, the inhibition effect of the peony root bark extract on the histamine release amount can be effectively enhanced; in addition, the results of comparative examples 5, 8, 11, 12 and 13 show that the Schisandra chinensis extract and the Zygosaccharomyces bifidus fermentation product extract have synergistic effect.
Test example 3 human body patch test.
1. The purpose of the test is as follows: the safety of examples 3 to 13 was examined.
2. Preparing facial mask liquid: examples 3-13 were each added to a facial mask solution prepared according to the formulation of table 5 below.
TABLE 5 facial mask liquid formulation
Preparation method of facial mask liquid
Adding 1, 3-propylene glycol, and adding xanthan gum, sclerotium rolfsii gum and hydroxyethyl cellulose into a stirring pot while stirring until the mixture is uniformly stirred and dispersed;
continuously stirring the allantoin, the trehalose, the amino acid humectant, the sodium hyaluronate and the EG-1 until the allantoin, the trehalose, the amino acid humectant, the sodium hyaluronate and the EG-1 are uniformly stirred and dispersed;
adding 70 parts of deionized water, and then heating to the system temperature of about 85-90 ℃;
standing, keeping the temperature for 20min for sterilization, slowly cooling to below 60 deg.C under stirring, adding sufficient deionized water, and adding collagen powder, vitamin B3, and K2 into the system;
continuously stirring and cooling to about 40 ℃, adding the composition into the system, continuously stirring for about 10min, stopping stirring, cooling, and then inspecting to discharge materials;
and sealing the storage barrel after discharging, and moving to a standing room for later use.
3. The test method comprises the following steps: a48 h closed patch test was used. Respectively weighing 0.02mL of diluted aqueous solution of different mask liquid products into a spot tester, and simultaneously setting a blank control group, wherein the control group is the diluent of the cosmetic. 50 healthy volunteers are selected, and the healthy volunteers are 18-24 years old and have no history of allergy. After cleaning the inner forearm of the subject, 0.02mL of sample was applied to a piece of filter paper attached to the plaque tester. The patch tester is applied to the inner side of forearm of the subject with non-irritating adhesive tape, and then is applied to skin by pressing with fingers for 48 h. The examinee is ordered to keep the spot-pasting part dry within 48h, and violent exercise, scratching the spot-pasting part, long-time sunlight irradiation and the like are avoided. After 48h, the tester is removed and marked, and after 30min, the pressure marks disappear under sufficient light for judgment and return visit observation is carried out within 72h and 96h respectively.
