JP4892833B2 - Fat absorption inhibitor - Google Patents

Description

  The present invention relates to a fat absorption inhibitor derived from a natural product that is effective for preventing and improving obesity and hypertriglyceridemia, and for preventing diseases such as diabetes, hyperlipidemia, hypertension and arteriosclerosis caused by obesity.

  Traditionally, Japanese meals have been mainly carbohydrates, but in recent years, Western-style meals such as fast food have become widespread and fat intake has increased. Looking at the nutrient intake per person per day in 2002, the ratio of lipid energy to energy intake is in excess of 25%, the upper limit of the appropriate ratio in the 20-40s. (Non-patent document 1).

  Fat overdose is the cause of obesity and serum hypertriglyceridemia. In obesity, insulin resistance is induced, and it is known that the incidence of diabetes, hyperlipidemia, hypertension, and arteriosclerotic diseases is high. Therefore, drugs that suppress the absorption of fat in foods are not only effective in preventing or improving obesity and serum hypertriglyceridemia, but also in diabetes, hyperlipidemia, hypertension, arteries caused by obesity. It is thought to contribute to improving the quality of life by preventing the onset of diseases such as sclerotic diseases.

  In fact, orlistat, an ethical drug marketed in Europe and the United States, is known to suppress fat absorption during meals and to exhibit an anti-obesity effect and an effect of improving serum hypertriglyceridemia. However, since orlistat has many reports of side effects such as gastrointestinal disorders and fatty stool, there is a demand for a natural product-derived fat absorption inhibitor that has a mild action and is highly safe even when ingested over a long period of time.

  Triglycerides, which account for most of the fat in food, are broken down into fatty acids and monoglycerides by lipases secreted from the stomach and pancreas and absorbed in the small intestine. Therefore, in order to suppress the absorption of fat, two mechanisms of inhibition of lipase or inhibition of fatty acid and monoglyceride absorption in the small intestine can be considered. At present, it is lipase inhibitors that actually have an action of suppressing fat absorption, and the action has been reported in many lipase inhibitors including the aforementioned orlistat.

  Conventionally, defatted cocoa mass (Patent Document 1) is known as a material derived from a natural product that suppresses fat absorption. Examples of natural products exhibiting a lipase inhibitory action include Dokatsu, Ryoko, Betel, Beehi, Sunpens and Ketsumeishi (Patent Document 2), Lemongrass, Allspice, Cinnamon or Clove (Patent Document 3), Alfalfa extract, Bitter Dingcha extract, Gold and silver flower extract, Peppermint extract, Clove extract, Kizuta extract, Olive extract and Luffa tea extract (Patent Document 4), Walnut, Western primrose, Bodaiju, Asparagus, Ginkgo, Huanalpomacho Plant, royal jelly (Patent Document 5), and the like are disclosed.

  Bald eagle is a dried root of the plant of the family Ranunculaceae, Pulsatilla chinensis. As pharmacological actions, cardiotonic action, peripheral vasodilatory action, vasoconstriction action governed by visceral nervous system, anti-amoeboid protozoa action, anti-vaginal trichomonas action, and antibacterial action are known. In Kampo, it is used for cleansing and detoxification purposes.

  The honey beetle (Mitsumonka) is a flower of Buddleia officinalis Maxim, which is collected before the flower opens, and dried. Although there are few reports on pharmacological effects, it is used for antipyretic, anti-inflammatory and ophthalmic treatments.

  Kite spruce (sea paulownia bark) is a dried bark of the leguminous deigo (Erythrina indica L. = E. variegata L. var. Orientalis (L.) Merr.). The citrus family Zanthoxylum ailanthoides Sieb. Et zucc., The scallop family Kalopanax pictus (thumb.) Nakagi, and the Panya family Bombax malabaricum DC. Yes. As a pharmacological action, an inhibitory action against skin fungi and Staphylococcus aureus has been reported. As a drug, it is used for analgesics such as rheumatoid arthritis, skin scabies and toothache.

  Hakushijin is a dried seed of seeds obtained by removing the skin from the seeds of the cypress family Thuja orientalis L. = Biota orientalis (L) ENDL. Although there are few reports on pharmacological effects, it is used for nourishment, tonic, insomnia, and constipation. Note that the branches and leaves of Konotegasiwa are known as Sakuhakuyo (acupuncture leaves), but their main components and uses are different from those of Hakushidin.

  Capsicum (winter coconut) is a dried mature seed of Benincasa cerifera Savi = B. hispida (Thumb. Cogn.). Although there are almost no reports on pharmacological action, it is used as an auxiliary agent for cough due to visceral suppuration (internal hemorrhoids) or fever as an antitussive, expectorant, drainage, anti-inflammatory diuretic (Non-patent Documents 2 and 3) ). In addition, although the fruit part of a chili pepper is known as a chili (winter basket) and is widely known as a diet food, the chili pepper which is the seed is different from a main component and a use.

Test Example 1 (Measurement of fat absorption inhibitory effect in rats)
SD rats (male) were divided into 2 groups with 7 rats per group and fasted for 16-20 hours from the day before the test. In one group, herbal extract was orally administered at a dose of 10 mL / kg, and immediately after that, ³ H-labeled triolein was orally administered at a dose of 1 mL / animal. Another group was used as a control group, and 10 mL / kg of purified water was orally administered instead of the herbal extract, and immediately after that, ³ H-labeled triolein was orally administered. In addition, the crude drug extract used what was diluted with purified water so that it might become 1g / 10mL as an extract. ^{For 3} H-labeled triolein, 0.25 nmol as triolein (486.55 kBq as radioactivity) is dispensed into a glass tube, the solvent is evaporated with nitrogen gas, and 1 mL of 0.5% Tween-80 solution is added and sonicated for 10 minutes. What was dispersed by using was used. 30, 60, 90, and 120 minutes after administration of ³ H-labeled triolein, blood was collected from the tail vein without anesthesia, and the blood was collected in a tube containing heparin. Plasma was separated by centrifugation, 50 μL of which was mixed well with 10 mL of scintillator solution, and radioactivity was measured using a liquid scintillation counter.

  The time course of 50 μL of plasma radioactivity in the control group and the crude drug extract administration group is shown in FIG. Furthermore, the area under the blood concentration curve (AUC) was calculated, and the decrease rate of AUC in the herbal extract extract group relative to the AUC in the control group was defined as the fat absorption inhibition rate (%) and shown in Table 1.
