Abstract
Description
Technical Field
[0001] This invention relates to the field of ultraviolet bactericidal synergist preparation technology, and particularly to a plant essential oil-based ultraviolet bactericidal synergist and a method for combining it with ultraviolet light for bactericidal action. Background Technology
[0002] Ultraviolet (UV) bactericidal synergists are compounds or substances that enhance the bactericidal effect of ultraviolet (UV) light. By working synergistically with UV light, they improve bactericidal efficiency and reduce the tolerance of microorganisms to UV light. UV sterilization achieves its effect by destroying the DNA or RNA molecular structure in microbial cells with UV light of a specific wavelength. The bactericidal effect of UV lamps is strongest at a wavelength of 253.7 nm because this wavelength coincides with the absorption peak of deoxyribonucleic acid in the nucleus of microbial cells.
[0003] Currently, with the widespread use of plant essential oil-based UV bactericidal synergists and the extensive use of antibiotics, the possibility of drug resistance development is low. However, long-term and excessive use may still lead to the development of drug resistance in microorganisms, making bacterial resistance increasingly serious. At the same time, the stability of plant essential oils may be affected by environmental factors such as light, temperature, and oxygen, which may reduce their effectiveness in practical applications. With the emergence of multidrug-resistant bacteria, UV bactericidal synergists are usually highly volatile, which may affect their bactericidal effect. Furthermore, the components of plant essential oils may have certain toxicity to aquatic organisms, resulting in poor degradation of UV bactericidal synergists in the environment and impacting the ecological environment.
[0004] Therefore, a plant essential oil-based ultraviolet bactericidal synergist and its combination with ultraviolet light for sterilization are proposed to solve the above problems. Summary of the Invention
[0005] The main objective of this invention is to provide a method for preparing plant essential oil-based ultraviolet bactericidal synergists, which can be applied in the preparation of plant essential oil-based ultraviolet bactericidal synergists.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a plant essential oil-based ultraviolet bactericidal synergist and a method for combining it with ultraviolet light for sterilization, comprising the following steps: Step 1: Prepare a mixture of lime and vegetable oil. Clean the reaction vessel and preheat it to 30°C to 50°C. Add lime and vegetable oil and fluorosilicone iodine in sequence, and stir and react for 40 minutes. After the reaction, lower the temperature to 20°C and continue stirring and reacting for 20 minutes. After the reaction is completed, cool to room temperature to obtain the mixture of lime and vegetable oil. Step 2: Add the lime vegetable oil mixture, fungicide, ultraviolet absorber, penetrant, and gibberellin organic solvent to the reaction vessel in sequence, and add ethylenediaminetetraacetic acid and diethylenetriaminepentaacetic acid. Heat the reaction vessel to 40°C and stir at a constant speed for 20 minutes. Then add salt water solution to the reaction vessel and stir again for 30 minutes to obtain a secondary mixture. Step 3: Add the drug-resistant solvent, reduce the temperature of the reaction vessel to 5°C to 20°C, add alumina, zinc oxide and silica gel to the secondary mixture, and continue stirring to obtain the plant essential oil-based ultraviolet bactericidal synergist.
[0007] The raw material weight ratio of the plant essential oil-based ultraviolet bactericidal synergist is as follows: penetrating solvent 10% to 15%, fungicide 5% to 10%, lime plant oil 10% to 20%, fluorosilicone iodine 10% to 15%, ultraviolet absorber 1% to 5%, gibberellin organic solvent 5% to 10%, gibberellin organic solvent 0.5% to 2%, saline solution 20% to 30%, ethylenediaminetetraacetic acid 0.5% to 1%, diethylenetriaminepentaacetic acid 0.5% to 1%, antimicrobial solvent 0.5% to 2%, alumina 0.5% to 1%, zinc oxide 0.5% to 1%, and silica gel 1% to 2%.
[0008] The stirring speed inside the reactor is between 80 and 120 r / min; The ultraviolet absorber is at least one of o-hydroxybenzophenones, benzotriazoles, salicylates, triazines, and substituted acrylonitriles; The mass ratio of lime vegetable oil to fluorosilicone iodine is 1:0.8.

[0010] The saline solution is composed of salt, chitosan, acetic acid and water in a weight ratio of 2:1:1:3. The mass ratio of ethylenediaminetetraacetic acid and diethylenetriaminepentaacetic acid is 1:1.
[0011] The permeation solvent is one or a mixture of N-methylpyrrolidone, N-ethylpyrrolidone, and N-octylpyrrolidone.

[0013] The antidote solvent also includes at least one of gentamicin and penicillin.
[0014] The mass ratio of alumina, zinc oxide and silica gel is 1:1:1.2.
[0015] A method for sterilization using a plant essential oil-based UV bactericidal synergist in conjunction with UV light, the specific method is as follows: Step 1: Mix the bacterial culture with lime oil and place it in a six-well plate. Set the UV irradiation conditions as follows: wavelength range 300 to 460 nm, power 18 W, distance from the six-well plate to the UV lamp 8 cm, and UV intensity 2.4 to 3.0 mW / cm². 2 ; Step 2: Preheat the UV chamber for 20-40 minutes, then place the six-well plate into the UV chamber and irradiate for 25-35 minutes.
[0016] The present invention has the following beneficial effects: 1. In this invention, a plant essential oil-based ultraviolet bactericidal synergist is prepared by adding ethylenediaminetetraacetic acid (EDTA) and diethylenetriaminepentaacetic acid (DTA). The combination of EDTA and DTA increases the stability of the ultraviolet bactericidal synergist, avoids the influence of environmental factors such as light, temperature, and oxygen on the stability of plant essential oils, increases the effectiveness of the ultraviolet bactericidal synergist, reduces the volatility of the ultraviolet bactericidal synergist itself, and improves the bactericidal effect.
[0017] 2. In this invention, by adding an antidote solvent, the prepared plant essential oil-based UV bactericidal synergist, when used, can effectively kill antibiotic-resistant bacteria by combining benzalkonium chloride in the antidote solvent with penicillin-type antibiotics. At the same time, penicillin can interfere with the cell wall synthesis of microorganisms, while benzalkonium chloride destroys the existing cell wall. The synergistic effect of the two enhances the bactericidal effect of the synergist, reduces the drug resistance of microorganisms, and makes the bacterial resistance weaker and weaker.
[0018] 3. In this invention, by adding alumina, zinc oxide, and silica gel, the prepared plant essential oil-based ultraviolet bactericidal synergist is used such that, when applied, alumina removes toxic components from the essential oil through capillary adsorption, while also reducing substances in lime oil that may be toxic to aquatic organisms. Silica gel effectively adsorbs toxic substances in lime essential oil, and zinc oxide is also an effective photocatalyst that degrades toxic components in lime essential oil under light. Furthermore, zinc oxide has excellent antibacterial properties, which helps improve the preservation stability of the essential oil and enhances the degradation effect of the ultraviolet bactericidal synergist in the environment, resulting in high environmental friendliness.

This reduces substances in lime oil that may be toxic to aquatic organisms. Silica gel can effectively adsorb toxic substances in lime essential oil, and zinc oxide is also an effective photocatalyst that can degrade toxic components in lime essential oil under light. At the same time, zinc oxide has good antibacterial properties, which helps improve the preservation stability of essential oils and enhances the degradation effect of ultraviolet bactericidal synergists in the environment.
[0038] The test results for irradiation dose, irradiation time, and UVC intensity are shown in Table 1 below: The test conditions were as follows: the UV lamp used was a PHILIPS TL-D brand; the power was 18W; the voltage was 220V; the wavelength was (UVA) 300-469nm; the lamp tube diameter was 25mm; and the length was 60cm.
[0039] The lime oil in question is an Italian brand. The test results were determined as follows: (1) Inoculate a single colony of Escherichia coli ATCC 25922 into a centrifuge tube containing 4 mL of MH broth, incubate at 220 rpm in a 37°C shaker for 4 hours, and then remove the centrifuge tube. (2) Place the centrifuge tube into the centrifuge, centrifuge at 1000 rpm for 8 min, discard the supernatant and add an equal volume of physiological saline to resuspend, and perform gradient dilution to make the final bacterial count 104 CFU / ml; (3) Add 1 mL of bacterial culture to a six-well plate; (4) Set up a blank control group and a UV irradiation treatment group, wherein the UV irradiation treatment group was divided into three groups, irradiated for 15 min, 30 min and 60 min respectively; (5) After the UV irradiation, 80 μL of bacterial culture was added to a 2 mL centrifuge tube containing 800 μL of 0.85% physiological saline for serial dilution. After dilution, 25 μL was dropped onto MH agar medium and incubated at 37 degrees Celsius for 16 to 18 hours. The bacterial culture was counted and the experimental results were statistically analyzed after three biological replicates.
[0040] As the irradiation time increased, the antibacterial effect of ultraviolet light on bacteria increased. In the 15-minute ultraviolet irradiation group, the number of bacteria was not significantly different from that in the blank control group, indicating that short ultraviolet irradiation time could not produce a significant antibacterial effect on ATCC25922. In the 30-minute ultraviolet irradiation group, the number of bacteria began to decrease, indicating that ultraviolet light began to have an antibacterial effect on bacteria.
[0041] Table 1: Testing of irradiation dose, irradiation time, and UVC intensity:
[0042] As can be seen from the test results in the table above, the heat-stable release agents prepared in Examples 1, 2, and 3, compared with the comparative example, avoid the potential impact of environmental factors such as light, temperature, and oxygen on the stability of plant essential oils, increase the effectiveness of the ultraviolet bactericidal synergist, improve the bactericidal effect of the synergist, reduce the drug resistance generated by microorganisms, help improve the stability of lime plant essential oil preservation, and enhance the degradation effect of ultraviolet bactericidal synergist in the environment.
[0043] This invention discloses a plant essential oil-based ultraviolet bactericidal synergist and its method for combined ultraviolet sterilization. In this method, the reaction vessel is first cleaned and preheated to 30°C to 50°C. Lime plant oil and fluorosilicone iodine are added sequentially, and the mixture is kept at this temperature with stirring for 40 minutes. After the reaction, the temperature is lowered to 20°C, and the stirring continues for another 20 minutes. After the reaction is complete, the mixture is cooled to room temperature to obtain a lime plant oil mixture. The lime plant oil mixture, fungicide, ultraviolet absorber, penetrating solvent, and gibberellin organic solvent are then sequentially added to the reaction vessel. Ethylenediaminetetraacetic acid (EDTA) and diethylenetriaminepentaacetic acid (DTA) were added, and the reaction vessel was heated to 40°C and stirred at a constant speed for 20 minutes. Then, a saline solution was added to the reaction vessel, and the mixture was stirred again for 30 minutes to obtain a secondary mixture. The combination of EDTA and DTA increases the stability of the UV bactericidal synergist, preventing the stability of plant essential oils from being affected by environmental factors such as light, temperature, and oxygen. This enhances the effectiveness of the UV bactericidal synergist, reduces its volatility, and improves the bactericidal effect. (Adding a drug-resistant solvent...) By combining benzalkonium chloride in the antimicrobial solvent with penicillin antibiotics, antibiotic-resistant bacteria can be effectively killed. Simultaneously, penicillin interferes with microbial cell wall synthesis, while benzalkonium chloride disrupts existing cell walls. The synergistic effect of these two enhances the bactericidal effect of the synergist, reduces the development of antibiotic resistance in microorganisms, and weakens bacterial resistance. The reaction vessel temperature is lowered to 5°C to 20°C, and alumina, zinc oxide, and silica gel are added to the secondary mixture. Alumina removes toxic components from the essential oils through capillary adsorption and also has a water-repellent effect. With low sensitivity, it is suitable for processing essential oils containing trace amounts of moisture, thus reducing substances in lime plant oil that may be toxic to aquatic organisms. Silica gel can effectively adsorb toxic substances in lime essential oil, and zinc oxide is also an effective photocatalyst that can degrade toxic components in lime essential oil under light. At the same time, zinc oxide has good antibacterial properties, which helps to improve the preservation stability of essential oils and enhance the degradation effect of ultraviolet bactericidal synergists in the environment. It has high environmental protection. Continue stirring to obtain a plant essential oil ultraviolet bactericidal synergist.
