(Industrial Application Field) This invention relates to a substance that prevents thrombosis, etc., and its purpose is to inhibit the production of lipoxygenase metabolites of arachidonic acid such as 5-HETE, which are the cause of worsening symptoms of thrombosis, so that an antithrombotic effect can be expected. The goal is to provide substances that prevent blood clots. (Background of the Invention) Generally, a thrombus is a state in which blood clots within a blood vessel, and due to phenomena such as damage to the vascular endothelium, inflammation, or ulcer, platelets, thrombocytes, white blood cells, and fibrin are present at the site. , red blood cells, etc. gather and form a sticky thrombus, resulting in lumen narrowing and occlusion. This thrombus occurs due to causes such as increased red blood cells, water deficiency, anemia, bleeding, malignant ulcers, and obesity.When it occurs in a vein, it causes changes in blood flow and blood flow congestion, and when it occurs in an artery, it causes peripheral blood clots. It is said to lead to conditions such as blood circulation disorders and tissue necrosis. From a biochemical perspective, this thrombus is caused by damage to the vascular endothelium.
When platelets, etc. start aggregating at the site due to a phenomenon such as inflammation or ulcer, TXB2 and HHT, which are metabolites of arachidonic acid, are released.
TXB2 and HHT are also thought to synergistically promote blood aggregation. TXB2, a metabolite of this arachidonic acid,
HHT is converted by cyclooxygenase into leukotrienes that protect blood vessel walls, while arachidonic acid is metabolized by lipoxygenase into 5-HETE and 12-HETE, which are antagonists of leukotrienes. Since it is metabolized to prostaglandin, substances that inhibit the production of lipoxygenase metabolites of arachidonic acid, that is, those that specifically (selectively) inhibit the activity of lipoxygenase, which is an enzyme metabolizing arachidonic acid, are required to prevent the above-mentioned thrombosis. It is considered to have extremely high preventive ability. (Prior art and its drawbacks) Conventional treatments for such thrombosis include administration of heparin, an acidic mucopolysaccharide, but currently only surgical methods are effective. There is said to be no cure. (Progress of the Invention) Therefore, in order to eliminate all of the above-mentioned conventional drawbacks, the inventor endeavored to discover a specific (selective) inhibitor of lipoxygenase, and found that the leaves had not been previously used as a substitute for cigarettes. It was discovered that Japanese knotweed (Reynoutria japonica Houtt), a plant of the Polygonaceae family that was consumed as tea or as a tea, had this effect. Alternatively, it was discovered that when applied as a food, it is effective in preventing and eliminating the thrombotic symptoms, etc., and the present invention was achieved. (Solution) That is, in this invention, Japanese knotweed (Reynoutria
japonica Houtt) and/or an extract extracted from this Japanese knotweed (Reynoutria japonica Houtt), particularly a thrombus characterized in that the extract extracted from this Japanese knotweed contains a stilbene compound represented by the following structural formula (1). By providing a preventive substance, all of the above-mentioned conventional problems are solved. [When R 1 = R 2 = H, resveratrol, R 1

japonica Houtt) is a perennial plant of the Polygonaceae family, and all parts of this plant (above-ground parts, underground parts (tubers, basal roots, roots), seeds, etc.) can be suitably used without limitation, but especially roots can be used as raw materials. In the present invention, in order to obtain a dry powder of Japanese knotweed, it is first dried by any of known natural drying, hot air drying, or freeze drying, and then the dried product is pulverized by a known mechanical pulverization (ball mill). - Screw). In this invention, this powder can also be effectively used as an essential compounding ingredient. Next, the extract is obtained from the above dry powder as follows. First, non-dried Japanese knotweed is cut into small pieces. This shredded product or the dried powder is extracted with a lower aliphatic alcohol. If this extract is concentrated or dried and used, it can be used as an essential component of the thrombosis prevention substance according to the present invention. , the shredded material or the dried powder is extracted with acetone-methanol, filtered, the filtrate is further extracted with ethyl ether, and the ethyl ether hardly soluble portion is purified by column chromatography and repurified with ethanol to obtain the following stilbene compound. is obtained in the form of colorless crystals.Of course, without necessarily refining it to a stilbene compound, the ethyl ether hardly soluble portion can be simply evaporated to dryness and used as a component of the food for preventing blood clots, etc. according to the present invention. In this invention, it can be used as an essential compounding component even at the stage of this concentrated liquid, and it can also be used as a compounding component at the stage of a dry product.The stilbene compound obtained in this way has the following formula (1 ), resveratrol, piceide,
2,3,5,4'-tetrahydroxystilbene-
It is a compound consisting of 2-0-D-glucoside. [When R 1 = R 2 = H, resveratrol, R 1

In order to use the dry powder of Reynoutria japonica Houtt or the extract (stilbene compound purified as required) from this Japanese knotweed (Reynoutria japonica Houtt) as an essential ingredient, the substance for preventing blood clots, etc. according to the present invention must be prepared by a normal employee. It may be in any pharmaceutical or food form that allows for the application of dry powder such as Japanese knotweed in an amount of about 200 mg to 1000 mg per day. Specific examples of the form include powders, granules, tablets, oral solutions, soft drinks, and confectionery. In the present invention, any pharmaceutical or food form may be prepared by adding excipients, fillers, sweeteners, and flavors according to conventional methods. (Effect of the invention) As described above, the substance for preventing blood clots, etc. according to the present invention is as follows:
Japanese knotweed (Reynoutria japonica Houtt) and/
Or this Japanese knotweed (Reynoutria japonica)
Since it is a thrombosis preventive substance that contains an extract extracted from Houtt as an essential component, it specifically inhibits the production of lipoxygenase metabolites of arachidonic acid such as 5-HETE, which are the cause of worsening symptoms of thrombosis, as shown in the test example below. Therefore, it is a food with extremely high ability to prevent thrombosis. Furthermore, when the thrombus prevention substance according to the present invention is prepared in the form of a food, it is not a pharmaceutical, so there is no need to seek diagnosis and instructions from a doctor for treatment, and the effect can be easily applied at home.
