Description

Technical Field

[0001] The present invention relates to the technical fields of natural product chemistry and daily chemical product preparation, and particularly relates to a toothpaste containing extracts of Dryobalanops aromatica Background Art

[0002] Oral health is an important part of overall health, and good oral hygiene habits can effectively prevent various diseases. As a basic product for daily oral care, toothpaste plays a key role in cleaning teeth, removing food residues, and preventing dental caries. In recent years, with the increasing attention to oral health, the demand for antibacterial or anti-inflammatory functions has also been growing. Therefore, developing toothpaste with antibacterial or anti-inflammatory effects has important application value.

[0003] Two chemical synthetic drugs, sodium copper chlorophyllin and tranexamic acid, have excellent antibacterial or anti-inflammatory effects. Currently, some commercially available antibacterial drug toothpastes and anti-inflammatory drug ointments often add these two ingredients. However, chemical synthetic drugs often bring some side effects, or require the use of precious metal catalysts and highly toxic neutralizing agents in the synthesis process, which not only increases production costs but also harms the environment.

[0004] In summary, developing a toothpaste with natural antibacterial or anti-inflammatory effects has broad application prospects. Summary of the Invention

[0017] Take the leaves and branches of Dryobalanops aromatica and add them to a steam distillation device, then add water, heat to boiling and carry out steam distillation for 1 - 2 h. After the distillation is completed, obtain the essential oil of the leaves and branches of Dryobalanops aromatica, and take the essential oil of the leaves and branches of Dryobalanops aromatica to obtain the extract of the leaves and branches of Dryobalanops aromatica.

[0018] Preferably, the weight ratio of the leaves and branches of Dryobalanops aromatica to water is 1:2 - 5.

[0019] Most preferably, the weight ratio of the leaves and branches of Dryobalanops aromatica to water is 1:3.

[0020] Preferably, the preparation method of the extract of the leaves and branches of Dryobalanops aromatica further comprises the following steps:

[0021] After the distillation is completed, take the residue of the leaves and branches of Dryobalanops aromatica, then carry out heating reflux extraction with an organic solvent. After the extraction is completed, take the extract, concentrate and dry the extract to obtain the organic solvent extract of the leaves and branches of Dryobalanops aromatica;

[0022] Take the organic solvent extract of the leaves and branches of Dryobalanops aromatica and mix it with the essential oil of the leaves and branches of Dryobalanops aromatica to obtain the extract of Dryobalanops aromatica.

[0023] In further research, the inventor found that in toothpaste, adding the extract of Cinnamomum camphora leaves and twigs obtained by mixing the organic solvent extract of Cinnamomum camphora leaves and twigs with the essential oil of Cinnamomum camphora leaves can significantly improve the anti-inflammatory effect of toothpaste compared to adding only the essential oil of Cinnamomum camphora leaves.

[0024] Preferably, the organic solvent consists of cyclohexane and acetone.

[0025] In further research, the inventor found that the selection of the extraction solvent for the organic solvent extract of Cinnamomum camphora leaves and twigs is crucial; in toothpaste, only by adding the extract of Cinnamomum camphora leaves and twigs obtained by mixing the organic solvent extract of Cinnamomum camphora leaves and twigs extracted with an organic solvent consisting of cyclohexane and acetone with the essential oil of Cinnamomum camphora leaves can the anti-inflammatory effect of toothpaste be significantly improved compared to adding only the essential oil of Cinnamomum camphora leaves; however, adding the extract of Cinnamomum camphora leaves and twigs obtained by mixing the organic solvent extract of Cinnamomum camphora leaves and twigs extracted with a single cyclohexane or acetone or other organic solvent with the essential oil of Cinnamomum camphora leaves cannot significantly improve the anti-inflammatory effect of toothpaste.

[0026] More preferably, the volume ratio of cyclohexane to acetone is 100:50 - 60.

[0027] Most preferably, the volume ratio of cyclohexane to acetone is 100:55.

[0031] Most preferably, the weight ratio of the organic solvent extract of Cinnamomum camphora leaves and twigs to the essential oil of Cinnamomum camphora leaves is 1:1.

[0032] Preferably, the preparation method of the extract of Cinnamomum camphora leaves and twigs further comprises the following steps:

[0033] After the distillation is completed, take the residue of Cinnamomum camphora leaves and twigs, then carry out heating and reflux extraction with an organic solvent, take the extract after the extraction is completed, and concentrate and dry the extract to obtain the organic solvent extract of Cinnamomum camphora leaves and twigs;

[0034] The organic solvent extract of the leaves and branches of Dryobalanops aromatica is loaded onto a silica gel column. First, it is eluted and defatted with a mixed solvent composed of chloroform and methanol with a volume ratio of 100:5 - 10 and a volume of 3 - 6 times the column volume. Then, it is further eluted with a mixed solvent composed of chloroform and methanol with a volume ratio of 100:20 - 25 and a volume of 3 - 6 times the column volume. The eluate eluted with the mixed solvent composed of chloroform and methanol with a volume ratio of 100:20 - 25 is collected, concentrated and dried to obtain the silica gel column elution fraction of the leaves and branches of Dryobalanops aromatica.

[0035] The Dryobalanops aromatica extract is obtained by mixing the silica gel column elution fraction of the leaves and branches of Dryobalanops aromatica with the essential oil of the leaves and branches of Dryobalanops aromatica.

[0036] Most preferably, the organic solvent extract of the leaves and branches of Dryobalanops aromatica is loaded onto a silica gel column.

Then, it is further eluted with a mixed solvent composed of chloroform and methanol with a volume ratio of 100:22 and a volume of 3 - 6 times the column volume. The eluate eluted with the mixed solvent composed of chloroform and methanol with a volume ratio of 100:22 is collected, concentrated and dried to obtain the silica gel column elution fraction of the leaves and branches of Dryobalanops aromatica.

[0037] The inventors further found in their research that in toothpaste, adding the Dryobalanops aromatica extract obtained by mixing the silica gel column elution fraction of the leaves and branches of Dryobalanops aromatica prepared under the above silica gel column elution conditions with the essential oil of the leaves and branches of Dryobalanops aromatica can further significantly improve the anti - inflammatory effect of the toothpaste compared to adding the Dryobalanops aromatica extract obtained by mixing the organic solvent extract of the leaves and branches of Dryobalanops aromatica with the essential oil of the leaves and branches of Dryobalanops aromatica.

[0038] The inventors also found in their further research that the silica gel column elution conditions of the present invention are very crucial. In toothpaste, only by adding the Dryobalanops aromatica extract obtained by mixing the silica gel column elution fraction of the leaves and branches of Dryobalanops aromatica eluted under the silica gel column elution conditions of the present invention with the essential oil of the leaves and branches of Dryobalanops aromatica can the anti - inflammatory effect of the toothpaste be further significantly improved. However, adding the Dryobalanops aromatica extract obtained by mixing the silica gel column elution fraction of the leaves and branches of Dryobalanops aromatica eluted under other silica gel column elution conditions with the essential oil of the leaves and branches of Dryobalanops aromatica cannot further significantly improve the anti - inflammatory effect of the toothpaste.

[0039] Beneficial effects: The present invention provides a toothpaste containing Dryobalanops aromatica extract with a completely new composition. The toothpaste uses aluminum hydroxide, which has good cleaning and antibacterial effects, as an abrasive, so that the prepared toothpaste has good cleaning and antibacterial effects. In addition, by adding the extract of the leaves and branches of Dryobalanops aromatica to the toothpaste, the prepared toothpaste has an anti - inflammatory effect, which has important application value.

[0100] Experimental Example

[0101] The periodontal tissue is mainly composed of cells and extracellular matrix. Human gingival fibroblasts (HGFs) are an important component of the periodontal tissue. Human gingival fibroblasts play an important role in the formation, regeneration, function implementation and repair of the periodontal tissue. Lipopolysaccharide (LPS) is one of the main virulence factors of periodontal pathogenic bacteria, which can induce a large number of inflammatory response mediators and cytokines in different types of cells, causing periodontal tissue damage. In this experiment, the regulatory effect of the test sample on the inflammatory response of LPS-induced human gingival fibroblasts was tested through the IL-6 signaling pathway, as one of the supports for products to relieve gum problems.

[0102] Human gingival fibroblasts were seeded in 96-well plates and cultured with DMEM medium containing LPS (200 ng / g) for 24 h, and then changed to DMEM medium containing the test sample (160 mg / g). After 24 h, the cell supernatant was collected and centrifuged. The supernatant was aspirated, and the IL-6 content in the cell culture supernatant was measured using an ELISA kit to obtain the effect of the test sample on the IL-6 content of human gingival fibroblasts; 3 replicate wells were set for each test sample, and the experiment was repeated 3 times. At the same time, a negative control group without the test sample was tested according to the above method; the IL-6 inhibition rate was calculated; IL-6 inhibition rate (%) = [1 - (average IL-6 content of the test sample / average IL-6 content of the negative control)] * 100%.

[0103] In addition, the antibacterial rate of the test sample against Staphylococcus aureus was tested according to the method in the standard of "WS / T 650 - 2019 5.1.2".

[0104] The test samples were toothpastes containing extracts of Dryobalanops aromatica Gaertn. f. prepared in Examples 1 - 3 and Comparative Examples 1 - 5, and a toothpaste containing tranexamic acid prepared in Comparative Example 6; the test results are shown in Table 1.

[0105] Table 1. Anti-inflammatory experimental results of the toothpastes of the present invention

[0106] IL-6 inhibition rate Bacteriostatic rate Toothpaste containing borneol tree extract prepared in Example 1 12.38% 96.2% Toothpaste containing borneol tree extract prepared in Example 2 20.49% 99.8% Toothpaste containing borneol tree extract prepared in Example 3 33.75% 97.3% Toothpaste containing borneol tree extract prepared in Comparative Example 1 12.79% 96.8% Toothpaste containing borneol tree extract prepared in Comparative Example 2 16.82% 94.5% Toothpaste containing borneol tree extract prepared in Comparative Example 3 15.75% 99.6% Toothpaste containing borneol tree extract prepared in Comparative Example 4 23.18% 96.4% Toothpaste containing borneol tree extract prepared in Comparative Example 5 21.72% 97.9% Toothpaste containing tranexamic acid prepared in Comparative Example 6 27.69% 94.3%

[0107] It can be seen from the experimental results in Table 1 that the antibacterial rates of the toothpastes containing extracts of Dryobalanops aromatica Gaertn. f. prepared in the present invention are all above 90%; this shows that the toothpastes containing extracts of Dryobalanops aromatica Gaertn. f. prepared in the present invention have good antibacterial effects.

[0108] It can be seen from the experimental results in Table 1 that the IL-6 inhibition rate of the toothpaste containing extracts of Dryobalanops aromatica Gaertn. f. prepared in Example 1 is 12.38%; this shows that adding the essential oil of the leaves and branches of Dryobalanops aromatica Gaertn. f. to the toothpaste can make the prepared toothpaste have an anti-inflammatory effect.

[0109] As can be seen from the experimental results in Table 1, the IL-6 inhibition rate of the toothpaste containing the extract of Dryobalanops aromatica Gagnep. prepared in Example 2 is much higher than that in Example 1. This indicates that in toothpaste, the extract of Dryobalanops aromatica Gagnep. obtained by mixing the organic solvent extract of the leaves and branches of Dryobalanops aromatica Gagnep. with the essential oil of the leaves and branches of Dryobalanops aromatica Gagnep. can significantly enhance the anti-inflammatory effect of the toothpaste compared to simply adding the essential oil of the leaves and branches of Dryobalanops aromatica Gagnep.

[0110] As can be seen from the experimental results in Table 1, the increase in the IL-6 inhibition rate of the toothpaste containing the extract of Dryobalanops aromatica Gagnep. prepared in Comparative Examples 1-3 is not significant compared to that in Example 1. This indicates that the selection of the extraction solvent for the organic solvent extract of the leaves and branches of Dryobalanops aromatica Gagnep. is crucial. In toothpaste, only by adding the extract of Dryobalanops aromatica Gagnep. obtained by mixing the organic solvent extract of the leaves and branches of Dryobalanops aromatica Gagnep. extracted with an organic solvent composed of cyclohexane and acetone with the essential oil of the leaves and branches of Dryobalanops aromatica Gagnep. can the anti-inflammatory effect of the toothpaste be significantly enhanced compared to simply adding the essential oil of the leaves and branches of Dryobalanops aromatica Gagnep. However, adding the extract of Dryobalanops aromatica Gagnep. obtained by mixing the organic solvent extract of the leaves and branches of Dryobalanops aromatica Gagnep. extracted with a single cyclohexane or acetone or other organic solvents with the essential oil of the leaves and branches of Dryobalanops aromatica Gagnep. cannot significantly enhance the anti-inflammatory effect of the toothpaste compared to simply adding the essential oil of the leaves and branches of Dryobalanops aromatica Gagnep.

[0111] As can be seen from the experimental results in Table 1, the IL-6 inhibition rate of the toothpaste containing the extract of Dryobalanops aromatica Gagnep. prepared in Example 3 reaches 33.75%, which is further much higher than that in Example 2. At the same time, it is also significantly higher than that of the toothpaste containing tranexamic acid prepared in Comparative Example 6, showing excellent anti-inflammatory effects. This indicates that in toothpaste, adding the extract of Dryobalanops aromatica Gagnep. obtained by mixing the silica gel column elution fraction of the leaves and branches of Dryobalanops aromatica Gagnep. prepared under the silica gel column elution conditions of the present invention with the essential oil of the leaves and branches of Dryobalanops aromatica Gagnep. can further significantly enhance the anti-inflammatory effect of the toothpaste compared to adding the extract of Dryobalanops aromatica Gagnep. obtained by mixing the organic solvent extract of the leaves and branches of Dryobalanops aromatica Gagnep. with the essential oil of the leaves and branches of Dryobalanops aromatica Gagnep., making the prepared toothpaste have excellent anti-inflammatory effects.

[0112] As can be seen from the experimental results in Table 1, the increase in the IL-6 inhibition rate of the toothpaste containing the extract of Dryobalanops aromatica Gagnep. prepared in Comparative Examples 4 and 5 is not significant compared to that in Example 2. This indicates that the silica gel column elution conditions of the present invention are crucial. In toothpaste, it is necessary to add the extract of Dryobalanops aromatica Gagnep. obtained by mixing the silica gel column elution fraction of the leaves and branches of Dryobalanops aromatica Gagnep. eluted under the silica gel column elution conditions of the present invention with the essential oil of the leaves and branches of Dryobalanops aromatica Gagnep. to further significantly enhance the anti-inflammatory effect of the toothpaste. However, adding the extract of Dryobalanops aromatica Gagnep. obtained by mixing the silica gel column elution fraction of the leaves and branches of Dryobalanops aromatica Gagnep. eluted under other silica gel column elution conditions with the essential oil of the leaves and branches of Dryobalanops aromatica Gagnep. cannot further significantly enhance the anti-inflammatory effect of the toothpaste.
