Hyperlipidemia refers to a disease of high blood fat content. Generally, when total cholesterol is over 240 ㎎ / dl or triglycerides are over 200 ㎎ / dl, it is called hyperlipidemia. Hyperlipidemia is known to be a major cause of hypertension, myocardial infarction, and stroke due to cholesterol blocks the blood vessels and inhibits blood circulation.

BACKGROUND ART In order to prevent or treat hyperlipidemia due to cholesterol, studies have been made on substances that inhibit the absorption of cholesterol. Currently, statin drugs are widely used for the treatment of hyperlipidemia due to inhibition of cholesterol absorption. The drug in this series is an inhibitor of Hmg-CoA reductase and has the effect of inhibiting cholesterol synthesis and lowering blood LDL-cholesterol. In addition, ezetimibe, niacin and fibrate preparations are mainly used. However, there is a possibility that side effects such as myalgia, constipation or digestive disorder and hepatic dysfunction are rarely observed when the drug is administered.

Hereinafter, the present invention will be described in detail with reference to examples.

Example : White mushroom  Water extract preparation

Fifty milliliters of water was extracted with 2 g of white oyster mushroom powder from Gyeongsangbuk-do Forestry Environment Research Institute, and the mixture was extracted with shaking incubator at 37 ℃ for 24 hours. The supernatant of the shaking incubator was centrifuged at 2500 rpm for 10 minutes, and the water extract of white mushroom was collected and stored at -20 ° C.

Experimental Example :

1. Results of measurement of pancreatic cholesterol esterase activity by water extract of white oyster mushroom

Pancreatic cholesterol esterase plays a role in recognizing acyl chain-bearing substrates as non-specific and isolating acyl chains. To measure the pancreatic cholesterol ester raising activity by the white oyster mushroom water extract of the Example, a poison flinic acid cholesterol ester raise made by Sigma chemical was used as an enzyme. The pancreatic cholesterol esterase cleaved the chromogenic substrate (p-nirophenylbutyrate), and the activity of the enzyme was confirmed by the color reaction. The inhibitory effect of the enzyme was measured by the change of absorbance at 405 nm using a microplate reader and calculated as% based on the absorbance at 405 nm of the untreated group of white mushroom water extract.

As a result, it was confirmed that the water extract of White oyster mushroom reduced pancreatic cholesterol ester raising activity in a concentration-dependent manner. The results are briefly shown in Fig.

2. Measurement and Results of Pancreatic Lipase Activity by White Oyster Water Extract

Pancreatic lipase plays a role in recognizing acyl chain-bearing substrates nonspecifically and isolating acyl chains. Porcine pancreatic lipase type 2 (Sigma chemical, Type II, manufactured by Sigma Chemical Co., Ltd.) was used as an enzyme to measure the pancreatic lipase activity by the white oyster mushroom water extract. Using pancreatic lipase's ability to decompose chromo-genic substrate (p-nirophenylbutyrate), the activity of the enzyme was confirmed through color development. The inhibitory effect of the enzyme was measured by the change of absorbance at 405 nm using a microplate reader and calculated as% based on the absorbance at 405 nm of the untreated group of white mushroom water extract.

The activity of the enzyme was determined by the water extract of white oyster mushroom. As a result, the pancreatic lipase activity of the white mushroom water extract of the Example was decreased in a concentration-dependent manner. The results are briefly shown in Fig.

3. Measurement of Neutral Fat Absorption by Water Extract of White Oyster Mushroom

Plasma triglyceride was measured to determine whether the water extract of white mushroom extract of the Example showing inhibitory effect on pancreatic lipase activity was also effective at the individual level. A 0.5 ml oral fat suspension was orally administered to 8-week-old Balb / c mice (male, body weight ~ 25 g) fasted for 16 hours. The fat suspension consisted of 30% olive oil, 0.5% (w / v) carboxymethylcellulose sodium (CMC-Na) and 1% (v / v) Tween 80, 100 mg (4 g / kg) was added. After 2 hours, mouse blood was collected and centrifuged at 3000 rpm for 15 minutes at 4 ° C. The amount of triacylglycerol in the serum was measured using a serum triglyceride determination kit (Sigma). As a result, it was confirmed that the white oyster mushroom water extract of the Example lowered the neutral fat absorption. The results are briefly shown in Fig.
