Description

[0001] The present invention relates to a composition for preventing or treating obesity or bone metabolism diseases, which comprises germinated black rice extract as an active ingredient,

The present invention relates to a composition for preventing or treating obesity or bone metabolism diseases, which comprises germinated black rice extract as an active ingredient. The composition of the present invention is useful as a health functional food for preventing and treating bone metabolism such as obesity or osteoporosis, And in the manufacture of pharmaceuticals.

Osteoporosis refers to a skeletal disorder in which the risk of fracture and bone fragility are increased due to low bone mass and bone destruction. Osteoporosis is a particularly frequent occurrence in postmenopausal women, a disease in which the amount of bone is markedly reduced by the decreased secretion of estrogen. The decrease in the amount of bone may be due to individual differences or various other causes, but if the amount of bone excessively decreases and falls below a predetermined value, fracture easily occurs even in a small impact. Osteoporosis can not lead to a healthy life by restricting long-term activities due to various fractures caused by weakening of the bones, especially femur fracture or vertebral fracture, rather than the symptom itself, resulting in 15% of the elderly death It is known.

Osteodystrophy is also called bone dystrophy and is a bone disease caused by chronic renal failure. It is born by abnormally abnormal kidney function, and when the kidney is weak, it does not dialyse. This kind of bone disease is called Renal Osteodystrophy. Bone diseases associated with osteophagia include osteomalacia fibrous osteitis (osteitis fibrosa).

On the other hand, black rice (Oryza sative L) is native to Thailand and has been cultivated in Jindo since 1991 in Korea. Black rice contains a large amount of selenium, and it has cancer prevention effect. There is a recent report in China that 40 patients with rectal cancer were treated with black rice for a prolonged period of time and the condition improved.

In 1998, professor Hwang Tae-Ik of the agriculture department of Chonnam National University also reported that the black rice has excellent efficacy in cancer cell removal and gastric ulcer treatment. In addition, vitamin B and vitamin E in black rice contains more than four times as much as ordinary rice, and it is effective for prevention of diabetes and adult diseases as well as female beauty.

As such, various studies have been conducted in the field of disease treatment or health functional food using black rice.

However, there is a growing interest in germinated grains as a health food, but there is little research on its efficacy in germinated black rice.
