Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a bone mass-promoting composition containing a wasabi extract as an active ingredient and exerting an anti-osteoporosis effect.

[0002]

2. Description of the Related Art Osteoporosis is a condition in which bone becomes brittle due to a decrease in bone mass. Osteoporosis not only causes bone fractures and severe pain, but also causes bedridden especially for elderly people.Therefore, effective treatment is required from the viewpoint of improving the quality of life in an aging society. ing. Active vitamin D3, female hormones (estrogens), calcitonin, ipriflavones have been used clinically as therapeutic agents for osteoporosis, and are recently based on the inhibitory effect of polyisoprenoid derivatives represented by vitamin K2 on osteoclast formation. An anti-osteoporosis agent (JP-A-7-215849) has also been developed.

[0003] On the other hand, recently, since it is difficult to treat osteoporosis after it has developed, it is important to strive for prevention, and it is essential to increase bone mass from a young age.
It has been deeply recognized that it is necessary to actively take nutritional components necessary for bone formation and foods that promote bone formation on a daily basis. Currently, calcium, magnesium, and vitamin D are mainly used as foods for strengthening bones. Casein phosphopeptides that promote the absorption of calcium from the intestinal tract have also been used. Furthermore, menaquinone (M
K) Vitamin K2 in foods known as -1 to 14
It is also considered to use.

[0004]

However, it has been found that active vitamin D3, a female hormone (estrogen) and calcitonin, which are used as a therapeutic agent for osteoporosis, have side effects and excessive symptoms, which is a problem. Recently, vitamin K2 has been used as a highly safe therapeutic agent for osteoporosis.
Vitamin K used for treatment
2 The dose must be as high as 45 mg a day. In this case, minor but sometimes side effects such as abdominal pain, nausea, vomiting, rash, and headache may occur. In addition, the efficacy and safety of ipriflavone when used for a long period of time are unclear. As described above, despite the development of various therapeutic agents for osteoporosis, since the drug is administered for a long period of time, the burden on the patient due to side effects and the like is large, and a satisfactory therapeutic effect is not always exerted.

[0005] On the other hand, the method of reinforcing the bone composition with foods such as calcium does not have a sufficient effect of increasing bone mass or increasing bone strength. In addition, vitamin K2
There are very few foods containing 1 ppm or more of vitamin K2, and natto (vitamin K2
Concentration, several to several tens of ppm).
Vitamin K2 is effective in treating osteoporosis even with its natto
If you try to consume natto, you have to eat several hundred grams of natto a day, which is problematic in taste. Therefore, development of foods with enhanced vitamin K2 has been attempted. However, when taking 45 mg a day like a therapeutic drug, side effects such as abdominal pain and rash may appear as described above, so that only a smaller amount can be used,
The effect is diminished if the amount is reduced.

[0006] Except for nutritional guidance, exercise is recommended to load bones and promote bone formation, but in reality,
As the age increases, exercise tends to be insufficient due to a decrease in physical strength and energy. Naturally, exercise alone cannot sufficiently maintain and increase bone mass and bone strength. As described above, although there is a demand for the development of a safe functional food having an excellent effect of preventing or treating osteoporosis, a product which has solved both the efficacy and the safety has not been developed at present.

[0007]

[Performance test of the present invention]

Test Example Bone Mass Enhancement Effect Test [Explanation of Experimental Method] Wasabia petiole (wasabija ja)
(Ponica MATSUM) was homogenized by adding a three-fold amount of a 20% ethanol solution, followed by centrifugation (8000 rpm for 20 minutes) to separate into a supernatant and a precipitate. An equal volume of ethyl ether was added to the supernatant and shaken, and the aqueous layer was separated. The obtained aqueous layer was further subjected to an operation of adding ethyl ether twice and shaking to remove ether-dissolved components. The aqueous layer obtained here was freeze-dried under vacuum to obtain a freeze-dried sample of wasabi extract (sample 1).

[0015] The bone mass enhancement effect test of Sample 1 was performed by cutting out the parietal bone of a ddY mouse (4 weeks old) and introducing a medium containing medium.
After transfer to a mm culture dish and culturing, the measurement was performed by measuring the amount of calcium in the bone tissue. As described above, a method for measuring the amount of calcium in the cultured tissue of the mouse parietal bone has been studied as one of the test methods for evaluating the effect of improving osteoporosis. The medium was 0.25% bovine serum albumin and antibiotics (10%).
0 units penicillin and 100 μg streptomycin / m
2.0 ml of Dulbecco's modified Eagle's medium (glucose concentration 4.5 g / dl). Tissue culture was performed using a carbon dioxide incubator at 37 ° C.
The reaction was performed for 48 hours under conditions of 5% carbon dioxide gas and 95% air in a water-saturated atmosphere at 50 ° C.

A lyophilized sample of wasabi extract was added to a medium.
The medium was added to a concentration of 0 μg / ml, and the amount of calcium in the bone tissue after the culture was compared with that of a control. The amount of calcium was represented by the amount of calcium per bone tissue dry weight. The dry weight was measured by drying the bone tissue at 100 ° C. for 5 hours. Calcium content is 12% for dry bone tissue.
It was decomposed with a 2 ml nitric acid solution at 0 ° C. for 5 hours and measured by a calcium C test (manufactured by Wako Pure Chemical Industries, Ltd.).

[Explanation of Experimental Results] Using the parietal bone tissue of the ddY mouse, a wasabi extract was added to the culture solution, and the result of 48 hours after the calcium content was measured is shown in Table 1. The numerical values were expressed as mean ± standard error. As shown in FIG. 1, the amount of calcium in bone tissue was significantly increased by adding the wasabi extract as compared to the control.

[0018]

[Table 1]

Further, by changing the concentration of the wasabi extract,
The results obtained by culturing the parietal bone of the ddy mouse for 48 hours and measuring the calcium content of the parietal bone tissue are shown in FIG. As shown in FIG. 1, when the wasabi extract was added so as to have a concentration of 250 μg / ml, no effect of increasing the amount of calcium was observed. However, the extract was added so that the concentration was 50 μg / ml or less. In this case, the amount of calcium in the bone tissue was significantly increased. In particular, when the medium was added to be 10 μg / ml, a high calcium amount increasing effect in the bone tissue was observed.

FIG. 2 shows the results of measuring the calcium content of the extract of food components other than wasabi after culturing the parietal bone of ddy mice for 48 hours. The amount of calcium in FIG. 2 was expressed as a ratio with respect to the control.
As shown in FIG. 2, the amount of calcium in the bone tissue was reduced as compared with the control even when a food component other than the wasabi extract was added, but the amount of calcium in the bone tissue was reduced only when the wasabi extract was added. An increase was observed.

[0021]

The composition of the present invention is safe because it is an extract of wasabi having a long history of eating, and can be taken on a daily basis for preventive purposes from a young age. In addition to protection, it can be expected to contribute to reducing medical costs in an aging society.
