Description

The present invention relates to an anti-obesity agent having lipase inhibitory activity and antioxidant properties for improving lifestyle-related diseases. More specifically, an anti-obesity agent for treating or preventing obesity caused by lipids present in foods and drinks by suppressing or inhibiting digestive absorption of lipids in vivo through lipase inhibitory action And lipase inhibitors. Moreover, since it has antioxidant activity, various diseases accompanying in-vivo oxidation can be prevented at the same time. Furthermore, a lipase inhibitor and an anti-inflammatory agent having antioxidative activity useful for suppressing rough skin and bad odor caused by lipids present in cosmetics and daily goods that come into direct contact with skin through a lipase inhibitory action And relating to antioxidants. Furthermore, regarding biological materials having antioxidant activity and lipase inhibitory activity, the extraction conditions were determined so that the components in the extract act as anti-obesity and lipase inhibitors or antioxidants. It is characterized by that.

In recent years, the Japanese diet has been approaching the Western style, and the calorie intake has been increasing year by year. In particular, the intake of fat, that is, animal fat, is remarkably increased. The calorie intake now exceeds the calorie consumption, and as a result, more fat deposition than necessary occurs in the body's adipose tissue and various organs, resulting in obesity.

Obesity is caused by constitutional factors, mental factors, central factors, metabolic factors, lack of exercise, etc. in addition to dietary factors, such as diabetes, hypertension, arteriosclerosis, thrombotic diseases and hyperlipidemia It is said to be a risk factor for lifestyle-related diseases. The Japanese Society of Obesity estimates that obesity is responsible for 30-60% of the 33 million hypertensive, 20 million hyperlipidemic, and 6.9 million diabetic patients. Furthermore, obesity in Japan has increased 2 to 4 times over the last 30 years, and is a major factor threatening the health of the people. In the future, as aging progresses, lifestyle-related diseases are considered to increase more and more, and prevention of obesity is becoming an important issue to be overcome not only from the health aspect but also from the social and economic aspects. In addition, obesity is limited in physical activity due to excessive fat accumulation in the body and places an extra burden on internal organs, etc., so complications such as hyperuricemia, cholelithiasis and gout are very frequent. It is the basis of the onset of high disease groups.

These lifestyle-related diseases and complications currently account for about 60% of Japanese death causes, and it is considered effective to prevent obesity for their treatment and prevention. Therefore, obesity improvement has become one of the social problems, and it is urgently desired to provide such a method.

In addition, women tend to crave a slim and firm body in view of the recent increase in obesity caused by overeating, lack of exercise, and stress. Therefore, the reduction of subcutaneous fat and the like is an important problem not only for health but also for beauty.

Methods for improving obesity are broadly divided into intake energy suppression systems and energy consumption promotion systems. Specific methods of energy intake suppression system include diet therapy, appetite suppressant administration, suppression of absorption due to adsorption of lipids in the digestive tract, formation of satiety due to indigestible dietary fiber, administration of digestive enzyme inhibitors, etc. There is no medication. Moreover, in the promotion system of energy consumption, there are exercise therapy, energy metabolism promoter administration, and the like.

However, in daily life, continuation of diet and exercise therapy takes a long time to become effective and requires a strong will, so it is extremely difficult to perform sustainably in a busy modern age. Often results in a temporary weight loss. It is known that transient weight loss causes rebound of weight and may trigger various lifestyle-related diseases, and is not preferable. In addition, there are pharmacotherapy as a means of assisting them, that is, a method using a central appetite suppressant, etc., but it is known that a central appetite suppressant has side effects, and there is a problem with safety. is there. Accordingly, it remains desirable to provide a method for improving obesity more safely.

In recent years, inhibitors against digestive enzymes have attracted attention for the purpose of combating obesity and preventing lifestyle-related diseases.
Fat is the highest calorie among food ingredients, and lipid accumulation is considered to be effective in preventing obesity. Lipases are digestive enzymes involved in the breakdown of ingested lipids and are secreted from the pancreas in humans. By lipase, neutral fat, that is, triglyceride (ester bond of triacylglycerol) is sequentially hydrolyzed to produce glycerol and fatty acid via diacylglycerol and monoacylglycerol. Excessive intake of lipids induces obesity and hyperlipidemia because these nutrient components are excessively absorbed from the small intestine. Therefore, inhibiting or suppressing lipase is considered to contribute to the suppression and prevention of obesity by lowering serum lipids and suppressing lipid accumulation in the body.

Developments that suppress and prevent obesity using this lipase inhibitory action are anti-obesity agents, anti-hyperlipidemic agents, and the like as drugs. In addition, harmful effects due to fat accumulation are observed not only in humans but also in animals such as livestock and pets, and such lipase inhibitors are highly useful as feed for livestock and pets.

On the other hand, neutral fat in sebum, which is a secretion from the skin, is a microorganism (Propionibacterium acnes, Pityrosporum ovale, Micrococcus sp., Etc.) that is resident in the surface layer of the human body. ) To produce free fatty acids. Free fatty acids are considered as one of the causes of skin diseases such as acne, dermatitis, and dandruff, because the inflammation progresses by accelerating the keratinization action of the skin and flowing into the surrounding connective tissue. Therefore, lipase inhibitors are also promising as cosmetics for preventing skin troubles.

Tetrahydrolipstatin disclosed in Academic Literature 1 is one of the anti-obesity drugs that excrete excess lipid using this lipase inhibitory action. However, there are many reports of side effects on this drug, and a safer lipase inhibitor is required. In particular, from the viewpoint of safety, application of a lipase inhibitory action using a component derived from a natural product is required. .

From such a point of view, various natural products that can be ingested on a daily basis are vigorously searched for components having strong lipase inhibitory activity, that is, natural components having lipid absorption inhibitory activity. For example, herbs, wheat and seaweeds disclosed in academic literatures 2 to 4 have been reported as materials, and further, Peonies, Oren, Psyllium, Buttonpi, Genpowder, Cha, Kujin disclosed in Patent Literature 1 are reported. Solvent extract of herbal medicine such as bell pepper, pumpkin, shimeji, maitake, fujiki, green tea, black tea, and oolong tea water extract disclosed in Patent Document 2, Dokatsu, Ryokyo disclosed in Patent Document 3, Extracts of betel nut, yobaihi, ketsumeishi, lemongrass, allspice, cinnamon, clove herbs disclosed in Patent Document 4, Asen, Guava, Medusweed herbs disclosed in Patent Document 5, patent Hongkong Sky, Iwabenkei, Savonsou, Bold, Paschaca, Tormentilla, et al. Plants consisting of Campuri, Turmeric isa, Chuchouashi, Cats claw, Cinnamon, Yam, Sendangsa, Uggi, Strawberry, Morge, Rose, Camellia, Hypericum perforatum, Tochu and white tea, Yucca, Ginseng, Jasmine disclosed in Patent Document 7 There are many others, including extracts from tea, yamako, yellow coffee, rooibos tea, soybean germ, ginger, and tochu tea.

In addition, phosphatidylcholine, tannin, and hesperidin disclosed in Academic Literatures 5-7, as well as tannins and flavonoids disclosed in Patent Literatures 8 and 9, and other components having a lipase inhibitory action are disclosed in Patent Literatures 10-14. And triterpenes, threonionine, lignin, dihydroflavanols, benzophenones and the like disclosed in US Pat.

Furthermore, from the viewpoint of anti-obesity, materials and ingredients that have lipase inhibitory activity as well as saccharide-degrading enzyme inhibitory activities such as amylase, maltase and sucrase have been reported. For example, with regard to the raw materials, grape seeds, oyster leaves, puer tea, hypericum, apples, cod, radish, banaba leaves, red mulberry, sanshuyu, coconut, eucommia leaves and patent document 16 disclosed in Patent Document 15 There are coleus foscolis, and there are tamarind seed coat extracts containing procyanidins as active ingredients disclosed in Patent Document 17, among others.

On the other hand, in recent years, oxidative stress in the living body has increased due to excessive intake of lipids or external stress, and as a result, active oxygen and free radicals are excessively generated in the living body. These are also said to change unsaturated fatty acids such as linoleic acid and linolenic acid contained in fats and oils into peroxy fatty acids and to hydroxylate bases constituting DNA to damage DNA. Furthermore, the accumulation of these changes damages various tissues, eventually causing pathogenesis such as inflammation, cardiovascular disease, diabetes, and malignant neoplasm (cancer), and has been shown to be associated with aging.

Originally, active oxygen and free radicals are produced by living organisms in the process of maintaining their lives using oxygen, and are essential substances for biological defense and metabolic systems. However, in modern society, excessive oxygen and free radicals are generated in vivo due to various mental stresses, excessive radiation and ultraviolet irradiation due to ozone hole decay, and excessive intake of carcinogens and lipids.

In particular, the skin is not only in contact with the outside air, but is constantly exposed to ultraviolet rays, and is said to be the most susceptible to oxidative stress, and its damage is considered to be great.
Sebum secreted on the skin is oxidized by ultraviolet rays or the like to become lipid peroxides, which causes damages such as wrinkles and spots on the skin and promotes aging. Therefore, it is considered that suppressing the production of lipid peroxide is effective not only in preventing deterioration of the skin (skin) state but also in preventing aging of the living body itself.

From such a viewpoint, various chemically synthesized antioxidants have been conventionally used. However, these chemically synthesized antioxidants have a problem in their safety in terms of carcinogenicity and the like, so consumers have a strong rejection reaction, and their usage is decreasing year by year. Therefore, expectations for highly safe natural product-derived antioxidants have recently been greatly increased, and many antioxidants derived from natural products have been reported. For example, natural antioxidants used by many natural products such as extracts of green tea polyphenols, mulberry leaves / leaves, Ibaranori, grapes and the like disclosed in Patent Documents 18 to 21 for antioxidants such as foods and cosmetics As proposed.

Thus, excessive intake of lipids has a risk of causing not only obesity and lifestyle-related diseases but also malignant neoplasms (cancer). On the other hand, acne and breakouts caused by a severe stress society, as well as rough skin due to intense ultraviolet rays, spots and freckles are also a major problem. Therefore, there is an urgent need to search for materials that can reduce oxidative stress at the same time as obesity prevention, materials that can prevent acne and skin diseases, that is, natural materials and ingredients that have both lipase inhibitory activity and antioxidant properties. .

Previous reports having both lipase inhibitory activity and antioxidant properties include POV elevation inhibitory substances and lipase inhibitory substances disclosed in Patent Document 22. However, since it is mainly provided as a cosmetic and is not the development of food materials and ingredients for the purpose of preventing obesity, there are currently no products that are satisfactory in terms of safety. Therefore, food materials and ingredients having these two functions have been awaited.

Antioxidant property is based on the radical scavenging ability of the test solution against DPPH (1,1-diphenyl-2-picrylhydrazyl) (Market, Takeshi Kiya, Oki Technical Research Report No. 1, pp. 9-22). (1998)). That is, 1.5 mM DPPH was dissolved in ethanol and diluted twice with distilled water to prepare a 0.75 mM DPPH solution. Next, 100 μl of a test solution having a dilution ratio of about 1.5 to 1093 (fold) is added to each well of the microplate, and 50 μl of DPPH solution is further added and mixed, and the absorbance at 515 nm after 20 minutes is obtained. It was measured. The absorbance when 50% ethanol was added instead of the test solution was taken as 100%, and the dilution factor corresponding to the absorbance of 50% was determined as IC50. That is, 125 μM of DPPH radicals are erased from the concentration dependence curve of DPPH radical scavenging ability of the test liquid when the vertical axis represents the DPPH radical elimination amount (%) and the horizontal axis represents the dilution ratio of the test liquid. The dilution ratio (IC50) of the test solution was determined.
