Description

  The present invention relates to a collagen synthesis promoter containing a pine bark extract and collagen and enhancing the ability of promoting collagen synthesis in vivo.

  Collagen is the main structural protein of the biological skeleton that occupies about 30% of the biological protein, plays an important role in maintaining the structure as a supporting tissue of the living body, and also exists in many tissues to protect cells and protect intercellular factors. It plays important physiological roles such as cell binding. In this way, collagen, which plays an important role in the living body, also decreases with the decline in metabolism due to aging, and various disorders, diseases, and illnesses associated with aging changes such as progress of aging and delayed recovery of diseases and chronic diseases. It is thought to cause etc. In particular, skin aging is likely to progress, and signs of aging are likely to be observed. Wrinkles and tarmi, which symbolize skin aging, are caused by a decrease in skin elasticity and flexibility, and such skin aging is based on a decrease in collagen.

  In addition, when a tissue is injured, a repair reaction takes place in vivo, and in the case of skin ulcers, granulation is formed, and in the case of fracture, tissue reconstruction such as callus formation occurs. These reconstructions are also deteriorated in the state of low metabolism, and by activating metabolism in the body and enhancing the process of tissue reconstruction, intractable skin diseases such as pressure ulcers, diabetic vascular ulcers or senile It can promote healing of fractures and bone defects.

  Furthermore, collagen is also important as a component constituting bone together with calcium, and it has been recognized that collagen synthesis needs to be active in order to form strong bone, and is also important for prevention of osteoporosis.

  Under such circumstances, compositions having a collagen production enhancing action have been proposed (for example, Patent Documents 1 and 2). Moreover, the present inventors have already found that the amount of collagen in the skin is enhanced by orally ingesting the pine bark extract (for example, Patent Document 3).

  Hereinafter, embodiments of the present invention will be described. In addition, this invention should not be limited and interpreted by description of the following embodiment, A various change is possible within the range of description in a claim.

  The biological collagen synthesis promoter of the present invention contains a pine bark extract and collagen, and at least one selected from calcium or a compound thereof, sodium or a compound thereof, magnesium or a compound thereof, zinc or a compound thereof It is characterized by containing these components.

(Composition of pine bark extract)
The pine bark extract used in the present invention contains proanthocyanidins as one of the main active ingredients. Proanthocyanidins refer to a group of compounds consisting of a condensation polymer having a degree of polymerization of 2 or more, with flavan-3-ol and / or flavan-3,4-diol as a structural unit. It is a powerful antioxidant produced by plants and is intensively contained in plant leaves, bark, fruit peel and seeds. This proanthocyanidin is a substance that cannot be produced in the human body.

When a pine bark extract containing this proanthocyanidin is ingested, an excellent lipid metabolism improving effect is obtained. The pine bark extract contains a condensation polymer having a degree of polymerization of 2 or more as proanthocyanidins, and further contains catechin and the like. In particular, proanthocyanidins containing a large amount of a condensation polymer having a low degree of polymerization are preferably used. The condensation polymer having a low polymerization degree is preferably a condensation polymer having a polymerization degree of 2 to 30 (2 to 30 mer), more preferably a condensation polymer having a polymerization degree of 2 to 10 (2 to 10 mer). Further, a condensation polymer (2 to 4 mer) having a polymerization degree of 2 to 4 is more preferable. Proanthocyanidins, which are condensation polymers having a degree of polymerization of 2 to 4 (2 to 4 mer), are particularly easily absorbed into the body. In the present specification, the polymer having a degree of polymerization of 2 to 4 is referred to as oligomeric proanthocyanidin (hereinafter referred to as “OPC”).

  Moreover, as a pine bark extract, 15% by mass, preferably 20% by mass or more, and more preferably 30% by mass of a condensation polymer having a degree of polymerization of 2 to 4 (2 to 4 mer; that is, OPC). An extract containing a pentamer or more proanthocyanidins in a proportion of 10% by mass or more, preferably 15% by mass or more is preferable.

  The pine bark extract may further contain catechins, and these catechins are preferably contained in a proportion of 5% by mass or more, more preferably 10% by mass or more. Catechin can be extracted together with proanthocyanidins (OPC) by the above extraction method. Catechin is a general term for polyhydroxyflavan-3-ol. As catechins, (+)-catechin (referred to as catechin in the narrow sense), (−)-epicatechin, (+)-gallocatechin, (−)-epigallocatechin, epigallocatechin gallate, epicatechin gallate, and afzelechin Etc. are known. In addition to the above (+)-catechin, gallocatechin, afzelekin, and (+)-catechin or 3-galloyl derivatives of gallocatechin have been isolated from the pine bark extract. Catechins are known to have a carcinogenic inhibitory effect, an active oxygen and free radical scavenging effect, and an antioxidant effect. In addition, catechins are known to have an antidiabetic effect that suppresses an increase in blood sugar. Catechins are poor in water solubility by themselves and have low physiological activity, but in the presence of OPC, catechins have the property of being activated at the same time as water solubility increases. Therefore, catechins work effectively when ingested with OPC.

  The catechins are preferably contained in the pine bark extract in an amount of 5% by mass or more. More preferably, the pine bark extract containing 20% by mass or more of OPC and 10% by mass or more of a pentamer or more of proanthocyanidins preferably contains 5% by mass or more of catechins. For example, when the catechin content of the pine bark extract is less than 5% by mass, the catechins may be added so that the content is 5% by mass or more. It is most preferable to use a pine bark extract containing 5% by mass or more of catechins, 20% by mass or more of OPC, and 10% by mass or more of proanthocyanidins of 5 or more.

(Pine bark extract)
Pine bark extracts used in the present invention include Pinus Martina, larch, Japanese black pine, Japanese red pine, Japanese pine, Japanese pine, Korean pine, Japanese pine, Ryukyu pine, Utsukushima, Japanese pine, white pine, Canadian Quebec region A bark extract such as Aneda is preferably used. Among these, a bark extract of French coastal pine is preferably used.

  French coastal pine is a marine pine that grows on the Atlantic coast of southern France. The bark of this French coastal pine contains organic acids and other physiologically active components in addition to containing proanthocyanidins, which are flavonoids, as main components. This main component, proanthocyanidins, is known to have a strong antioxidant action to remove active oxygen.

  The pine bark extract is obtained by extracting the pine bark with water or an organic solvent. When water is used, warm water or hot water is used. As an organic solvent used for extraction, methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, butane, acetone, hexane, cyclohexane, propylene glycol, hydrous ethanol, hydrous propylene glycol, ethyl methyl ketone, Organic solvents that are acceptable for the production of food or drugs such as glycerin, methyl acetate, ethyl acetate, diethyl ether, dichloromethane, edible oils and fats, 1,1,1,2-tetrafluoroethane, 1,1,2-trichloroethene Preferably used. These water and organic solvents may be used alone or in combination. In particular, hot water, hydrous ethanol, hydrous propylene glycol and the like are preferably used.

  The extraction method from pine bark is not particularly limited, and for example, a warm extraction method, a supercritical fluid extraction method, or the like is used.

  The supercritical fluid extraction method is a method of performing extraction using a supercritical fluid that is a fluid that exceeds the critical point (critical temperature, critical pressure) of a gas-liquid substance. As the supercritical fluid, carbon dioxide, ethylene, propane, nitrous oxide (laughing gas) or the like is used, and carbon dioxide is preferably used.

  In the supercritical fluid extraction method, an extraction process for extracting a target component with a supercritical fluid and a separation process for separating the target component and the supercritical fluid are performed. In the separation step, any one of extraction separation by pressure change, extraction separation by temperature change, and extraction separation using an adsorbent / absorbent may be performed.

  Moreover, you may perform supercritical fluid extraction by the entrainer addition method. In this method, for example, ethanol, propanol, n-hexane, acetone, toluene, other aliphatic lower alcohols, aliphatic hydrocarbons, aromatic hydrocarbons, and ketones are added to the extraction fluid in an amount of 2 to 20 W / V. Add about% and perform supercritical fluid extraction using this fluid to dramatically increase the solubility of the target extract, such as OPC and catechins, in the extraction solvent, or enhance the selectivity of the separation. This is a method for obtaining an efficient pine bark extract.

  Since the supercritical fluid extraction method can be operated at a relatively low temperature, it can be applied to substances that are altered or decomposed at high temperatures, the advantage that the extraction fluid does not remain, and the recycling of the solvent is possible. There is an advantage that the process can be omitted and the process becomes simple.

  Extraction from pine bark may be performed by a liquid carbon dioxide batch method, a liquid carbon dioxide reflux method, a supercritical carbon dioxide reflux method, or the like other than the above extraction method.

  For extraction from pine bark, a plurality of extraction methods may be combined. By combining a plurality of extraction methods, it becomes possible to obtain pine bark extracts having various compositions.

  The pine bark extract obtained by the above extraction is safe to be purified by ultrafiltration or a column method or a batch method using an adsorptive carrier (Diaion HP-20, Sephadex-LH20, chitin, etc.). From the viewpoint of

  Specifically, the pine bark extract used in the biological collagen synthesis promoter of the present invention is prepared by the following method, but this is illustrative and is not limited to this method.

  1 kg of French coastal pine bark is placed in 3 L of a saturated aqueous solution of sodium chloride and extracted at 100 ° C. for 30 minutes to obtain an extract (extraction process). Thereafter, the extract is filtered, and the resulting insoluble matter is washed with 500 mL of a saturated solution of sodium chloride to obtain a washing solution (washing step). The extract and washing solution are combined to obtain a crude extract of pine bark.

  Next, 250 mL of ethyl acetate is added to the crude extract and the phases are separated, and the process of recovering the ethyl acetate layer is repeated 5 times. The collected ethyl acetate solutions are combined and added directly to 200 g of anhydrous sodium sulfate for dehydration. Thereafter, the ethyl acetate solution is filtered, and the filtrate is concentrated under reduced pressure until the original volume is reduced to 1/5. The concentrated ethyl acetate solution is poured into 2 L of chloroform, and the resulting precipitate is collected by filtration. Thereafter, the precipitate is dissolved in 100 mL of ethyl acetate, and then added again to 1 L of chloroform and precipitated for washing twice. By this method, for example, about 5 g of pine bark extract containing 20% by mass or more of proanthocyanidins having a degree of polymerization of 2 to 4 and 5% by mass or more of catechins is obtained. Here, the content of the specific component in the extract is a value based on the dry mass of the extract. The same applies hereinafter.
