Description

TECHNICAL FIELD The present invention relates to a pharmaceutical composition for treating and preventing liver diseases containing an ultra-high-pressure-treated soybean sprout extract, and a health functional food for liver protection, which comprises a soy protein sprout sugar dipping extract by high hydrostatic pressure}

The present invention relates to a health functional food for liver protection comprising a natural plant extract as an active ingredient, or a pharmaceutical composition for the treatment and prevention of liver diseases.

Bean sprout is a germinated soybean which can be easily grown in a short time regardless of the season, making it an economical and nutritional supple food. The color of bean sprouts is white or light yellow, and it contains a lot of vitamin B 1, vitamin B 2 and vitamin C.

As a prior art that includes bean sprouts in some compositions, Korean Patent Publication No. 2011-0108686 discloses antioxidant activity of extracts obtained by treating a complex of natural plant extracts containing glucosidase as one of the alternative components of soybean sprout extract Korean Patent No. 098109 discloses a food composition for removing hangover which comprises an extract of more than a dozen kinds of natural plants including calcium compounds and bean sprouts. In Korean Patent No. 0504351, other plant extracts Together with a bean sprout juice in some compositions.

As a prior art that includes bean sprouts as a main constituent, Korean Patent Registration No. 0989869 discloses a hangover relieving effect of a fermented soybean sprout which is naturally fermented by adding rice extract and sugar to bean sprouts.

Thus far, the prior art has been used as a simple extract of raw bean sprouts, hot water of dried bean sprouts, or alcohol, and has not been shown to have sufficient hepatoprotective effect only by bean sprouts juice or bean sprouts extract. Therefore, In the present invention, it has been found that a component having an effect on liver protection contained in bean sprouts can be extracted through ultra-high pressure and sugar dipping, thereby achieving a remarkably excellent liver protecting effect.

An object of the present invention is to provide a health functional food for liver protection using an extract of a sugar bean sprout extract as an active ingredient.

It is also an object of the present invention to provide a pharmaceutical composition for prevention and treatment of liver disease, which comprises an extract of dicotyledonous extract of soybean sprout of ultra high pressure as an active ingredient.

The present invention also provides a method for extracting bean sprouts of ultrahigh pressure.

The present invention provides a health functional food for liver protection comprising an extract of a fermented soybean sprout of ultra high pressure as an active ingredient.

In addition, the present invention provides a pharmaceutical composition for prevention and treatment of liver diseases, which comprises an extract of a sugar beet of soybean sprout of ultra high pressure as an active ingredient.

In the present invention, it is preferable that the bean sprouts are treated at a pressure of 200 to 600 MPa, preferably 400 to 550 MPa, at a temperature of 15 to 35 DEG C for 1 to 30 minutes, preferably 2 to 10 minutes. When the ultrahigh pressure treatment pressure is lower than the above range, the extraction amount of asparagine and non-glycoside isoflavone is lowered and the hepatocyte protective activity is lowered. When the ultrahigh pressure treatment pressure exceeds the above range, the extraction amount of the asparagine and the non-glycoside isoflavone does not increase any more, and the hepatocyte protective activity is slightly lowered. When the ultra-high pressure treatment temperature is lower than the above range, the extraction amount of asparagine and non-glycoside isoflavone is lowered, and when the upper limit is exceeded, the hepatocyte protective activity is lowered. It is difficult to control the ultrahigh-pressure treatment time constantly below the above-mentioned range, and when the above-mentioned range is exceeded, the extraction amount of asparagine and non-glycoside isoflavone is no longer increased.

In the present invention, the sugarcane extract of bean sprouts treated with ultra high pressure is an extract obtained by immersing in at least one sugar selected from fructose, glucose, lactose, sugar, maltose and oligosaccharide. Preferably, the extract is fructose, Monosaccharides such as glucose, lactose, sugar, maltose, or disaccharides. Extract preparation is carried out at 15 to 35 DEG C, preferably at 15 to 25 DEG C for 2 to 48 hours, preferably 6 to 24 hours. Since the bean sprouts tissues are changed to be easily extracted through the ultra high pressure treatment, the extracting amount of asparagine and the extracting amount of substances exhibiting antioxidant activity are increased as compared with ordinary hot water extraction or alcohol reflux extraction under the above conditions. The mixing ratio of the bean sprouts treated with ultrahigh pressure and the sugar is 50-200 parts by weight per 100 parts by weight of bean sprouts treated with ultra high pressure and water discharged from bean sprouts during high pressure treatment. Since about 5 to 20% by weight of water is discharged from the bean sprouts through the ultra-high pressure treatment, the powdery sugar is sufficient to be mixed and immersed. However, if necessary, additional water may be added in an amount of about 5 to 10% .

The liver protection effect or the liver disease treatment and prevention effect of the present invention can be interpreted as a result of an increase in the content of the asparagine, the non-glycoside isoflavone or the ingredient not specified in the present invention contained in the sugar-immersion extract.
