[0081]

[0082] The present invention is described in detail through the following examples. The following examples are merely illustrative for the implementation of the present invention, and the scope of the present invention is not limited to the following examples.

[0083]

[0084] (Example 1) Preparation of propolis extract

[0085] A propolis extract was prepared by mixing 100 parts by weight of Australian propolis and 500 parts by weight of 95% ethanol, heating and extracting at 50°C for 10 hours, and then concentrating under reduced pressure.

[0086]

[0087] (Example 2) Preparation of propolis bioconversion extract

[0088] An extract was prepared by mixing 100 parts by weight of Australian propolis and 500 parts by weight of 95% ethanol, heating and extracting at 50°C for 10 hours, and then concentrating under reduced pressure.

[0089] After mixing the above extract, ethanol and polyethylene glycol, 1.5% of Lactiplantibacillus plantarum (owned by Megalab Co., Ltd.) derived from kimchi was inoculated and fermented at 30°C for 48 hours to produce a fermented product.

[0090] Ethyl acetate was added to the above fermented product, allowed to stand at room temperature for 10 minutes, and then centrifuged for 5 minutes to remove solid residue.

[0091] Afterwards, the ethyl acetate layer was concentrated under reduced pressure to prepare a propolis bioconversion extract.

[0092]

[0093] (Example 3) Preparation of propolis additional bioconversion extract

[0094] After mixing Australian propolis, ethanol, and polyethylene glycol, 1.5% of Lactiplantibacillus plantarum (owned by Megalab Co., Ltd., derived from kimchi) was inoculated and fermented at 30°C for 48 hours. After the fermentation process was completed, the first fermented product was produced by concentration under reduced pressure.

[0095] After mixing 100 parts by weight of the first fermentation product and 500 parts by weight of 95% ethanol, the mixture was heated and extracted at 50°C for 10 hours and then concentrated under reduced pressure to prepare an extract.

[0096] After mixing the above extract, ethanol and polyethylene glycol, 1.5% of Lactiplantibacillus plantarum (owned by Megalab Co., Ltd.) derived from kimchi was inoculated and fermented at 30°C for 48 hours to produce a second fermented product.

[0097] Ethyl acetate was added to the above second fermentation product, allowed to stand at room temperature for 10 minutes, and then centrifuged for 5 minutes to remove solid residue.

[0098] Afterwards, the ethyl acetate layer was concentrated under reduced pressure to prepare a propolis additional bioconversion extract.

[0099]

[0100] (Example 4) Total polyphenol content

[0101] To determine the total polyphenol content, 5 ml of the extract sample was collected and diluted with 5 ml of 10% ethanol. A 0.25 ml portion of each sample was then added to 95% ethanol containing 1% HCl and 4.55 ml of 2% HCl. After reacting for 15 minutes, the absorbance value of each sample was measured at 280 nm using a spectrophotometer.

[0102] Total polyphenol content was determined using a curve for gallic acid as a standard.

[0103] The total polyphenol content of the propolis extract of Example 1 was 0.48 mM / L, and the total polyphenol content of the propolis bioconversion extract of Example 2 was 0.52 mM / L, confirming that the polyphenol content increased through fermentation.

[0104]

[0105] (Example 5) TRAP activity of propolis extract

[0106] Tartrate resistant acid phosphatase (TRAP) activity was measured by seeding 1 × 10 RAW 264.7 cells in a 96-well plate. 4 The cells were pre-cultured for 24 hours at a number of cells / well, and the samples (propolis extract) were treated at various concentrations with differentiation-inducing medium [50 ng / mL receptor activator of nuclear factor-κB ligand (RANKL)].

[0107] Samples were added every two days when the medium was changed and cultured for a total of five days.

[0108] After removing the media, the cells were washed once with 50 μl of PBS (pH 7.4), and then 100 μl of 50 mM citrate buffer containing 10 mM sodium tartrate and 5 mM ρ-nitrophenylphosphate was dispensed, followed by reaction at 37°C for 1 hour.

[0109] After the reaction, the reaction was stopped with 0.1 N NaOH and the absorbance was measured at 405 nm.

[0110]

[0111] The results of measuring the activity of tartrate resistant acid phosphatase (TRAP), which is expressed specifically in osteoclasts, after differentiation of RAW 264.7 cells for 5 days by RANKL, an osteoclast differentiation inducer, using propolis extract are presented in Figure 1.

[0112] When the TRAP activity of the untreated sample (only RANKL treatment) was taken as 100%, the TRAP activity was 62.8% when 0.005% of the propolis extract of Example 1 was treated, and the TRAP activity was 49.8% when 0.005% of the propolis bioconversion extract of Example 2 was treated.

[0113] Propolis bioconversion extract, which is produced by fermenting or bioconverting propolis extract, can effectively inhibit the activity of TRAP induced by RANKL.

[0114] These results suggest that propolis bioconversion extract may have a positive effect on bone health by effectively inhibiting osteoclast formation and TRAP activity, thereby hindering bone resorption.

[0115]

[0116] (Example 6) TRAP staining of propolis extract

[0117] RAW 264.7 cells were seeded at 1×10 in a 24-well plate. 5After 24 hours of pre-incubation with the number of cells / well, the sample (propolis extract) was treated with differentiation-inducing medium [50 ng / mL receptor activator of nuclear factor-κB ligand (RANKL)] at various concentrations.

[0118] Samples were added every two days when the medium was changed and cultured for a total of five days.

[0119] After removing the media, the cells were washed once with 500 μl of PBS (pH 7.4), fixed with 4% formaldehyde for 10 minutes, and then fixed with ethanol / acetone (1:1) for 1 minute.

[0120] After washing twice with distilled water, TRAP staining was performed using leukocyte acid phosphatase kit 387-A (Sigma).

[0121] After staining, TRAP-positive multinucleated cells with three or more nuclei were counted using an optical microscope and used as an indicator of osteoclast production.

[0122]

[0123] The results of TRAP staining of propolis extract samples are presented in Figure 2.

[0124] As a result of identifying TRAP-positive multinucleated osteoclasts, propolis bioconversion extract (D) was found to reduce osteoclast formation at a concentration of 0.005%.

[0125]

[0126] (Example 7) TRAP activity of propolis mixed extract

[0127] Table 1 below shows the TRAP activity according to the mixture of propolis extracts.

[0128]

[0129] TRAP activity (%) RANKL only treatment 100 Propolis extract of Example 1 62.8 Propolis bioconversion extract of Example 2 49.8 Example 1 + Example 2 (20:80) 45.3 Example 1 + Example 2 (40:60) 60.4 Example 1 + Example 2 (5:95) 58.6 Example 3 + Example 2 (20:80) 43.9 Example 3 + Example 2 (40:60) 55.7 Example 3 + Example 2 (5:95) 57.1 Example 1 + Example 2 + Example 3 (10:100:20) 40.8 Example 1 + Example 2 + Example 3 (10:100:5) 56.6 Example 1 + Example 2 + Example 3 (10:100:35) 59.5

[0130]

[0131] As can be seen from the above table, the propolis bioconversion extract and the propolis extract can be used in combination, and when the weight ratio of the propolis bioconversion extract and the propolis extract is 70~90:10~30, the osteoporosis prevention effect is maximized.

[0132] In addition, the propolis bioconversion extract and the propolis additional bioconversion extract can be used in combination, and it can be seen that the osteoporosis prevention effect is maximized when the weight ratio of the propolis bioconversion extract and the propolis additional bioconversion extract is 70~90:10~30.

[0133] In addition, propolis bioconversion extract, propolis extract, and propolis additional bioconversion extract can be used in combination, and when the weight ratio of propolis bioconversion extract, propolis extract, and propolis additional bioconversion extract is 100:5~15:10~30, the osteoporosis prevention effect can be maximized.

[0134]
