The present invention relates to an anti-obesity composition comprising a goryanggang extract and a bamboo leaf extract, and the combination of goryanggang and bamboo leaf extract has excellent effects on the inhibition of adipocyte differentiation and changes in blood lipids, and furthermore, fenugreek, gilgyeong extract, etc. It relates to an anti-obesity composition further comprising a.

Obesity is a condition in which adipose tissue is accumulated in the body excessively. In the case of obesity, a person usually has a lot of weight, but even people with a lot of muscle can gain a lot of weight even if they are not obese. do. Obesity is induced by energy imbalance when excessive intake of nutrients compared to energy consumption over a long period of time, and other factors such as hormonal changes, genetics, mental health problems, and socioeconomic factors are complexly related. As the obesity population is increasing worldwide, it is recently pointed out as an important factor in causing adult diseases, and the severity of obesity is emerging as an important problem.

On the other hand, type 2 diabetes among diabetes mellitus is highly correlated with obesity. One of the transcription factors, peroxisome proliferation activated receptor (PPAR), is known to regulate gene expression of enzymes involved in lipid and glucose homeostasis and promote adipose tissue production. In addition, it is known that this change in donation of PPAR causes obesity. In addition, PPARγ is expressed in adipocytes and is a major transcription factor that converts preadipocytes into adipocytes, and is known to induce obesity by this mechanism.

In order to prevent and improve obesity and maintain a healthy weight, it is necessary to continuously manage it throughout life through a balanced diet and regular exercise. In particular, fat cells can be reduced in size once made, but it is impossible to remove them naturally, so it is important to prevent obesity from the beginning because they remain in the body permanently. For the prevention, improvement, or treatment of obesity, methods of reducing intake of calories, increasing activity and exercise, and taking drugs such as reducing fat absorption have been used.

Current treatments for obesity include fenfluramine, which inhibits the serotonin nervous system, ephedrine and caffeine via the noradrenergic nervous system, sibutramine, which acts simultaneously on the serotonin and noradrenergic nervous system, and orli, which reduces fat absorption by inhibiting lipase produced in the pancreas There are drugs such as start. However, among the previously used drugs, fenfluramine was banned because it caused side effects such as primary pulmonary hypertension or heart valve lesions. There is a problem that cannot be done.

Drugs for diet are divided into two mechanisms: inhibiting fat accumulation (appetite suppressants, lipogenesis inhibitors, etc.) or increasing fat activity (thermogenesis, lipolysis, etc.). Although it can be prescribed and taken after treatment, side effects such as digestive disorders and insomnia occur, so the need to develop natural raw materials to replace them is increasing.

It was confirmed that the combination of goryanggang and bamboo leaf of the present invention is an effective ingredient for suppressing obesity, and in addition, an experiment to increase its efficacy was conducted to develop an excellent combination for anti-obesity.

An object of the present invention is to provide a highly effective anti-obesity composition.

The present invention is an anti-obesity composition containing a goryanggang extract and a bamboo leaf extract as active ingredients. The ratio of the extract may be 50 to 150 parts by weight of the bamboo leaf extract based on 100 parts by weight of the goryanggang extract. Preferably, 100 parts by weight of the bamboo leaf extract is used in the same ratio.

In addition, the present invention is possible to increase the anti-obesity efficiency by further including fenugreek extract and gilkyung extract. The amount of the fenugreek extract to gilgyeong extract is suitably 25 to 75 parts by weight based on 100 parts by weight of the goryanggang extract, more preferably about 50 parts by weight.

And, in the composition, it is more effective to be administered at a dose of 3 to 9 mg/kg based on the goryanggang extract.

The anti-obesity composition of the present invention can maximize the anti-obesity function through synergy between the compositions.

Goryanggang ( Alpinia officinarum Hance) used in the present invention is a perennial herb with a height of about 1 meter belonging to the ginger family, and uses dried rhizomes harvested in autumn. It is called galangal and Asian ginger, and it is slightly different from general ginger ( Zingiber officinale Roscoe). Ordinary ginger (healthy) does not show as much effect as goryanggang. In consent treatment, it is effective for abdominal pain, vomiting, and diarrhea, and it is said that the treatment response is high for abdominal pain and diarrhea caused by eating cold food, drinks, or fruits, and it is effective for weakened kidney function and loss of energy due to poor circulation, diarrhea, and dysentery. The main components of essential oil include cineol, methylcinnamate, eugenol, pinene, and cardinene. In addition, flavonoids include galangin, kaemperid, kaampferol, quercetin, isoramnetine, galanzine-3-methyl ether, and the like, and galangol, etc., as a new ingredient. It is known that major pharmacological actions include gastric juice secretion promoting action, analgesic action, antioxygen deprivation action, antithrombotic action, anticoagulant action, and peripheral circulation improving action.

The present inventors confirmed that goryanggang also had an excellent antiobesity effect while studying the antiobesity effect of Chazugi, and in particular, the combination of goryanggang and bamboo leaf had an excellent antiobesity effect. Furthermore, the combination of these and Chazugi also showed a very good effect. The present inventors have confirmed that the extracts of goryanggang and bamboo leaves have effects such as suppression of adipocyte differentiation and changes in blood lipids, and presenting an anti-obesity composition comprising them as an active ingredient.

In addition, to identify a combination of additional extracts that increase the anti-obesity effect, and to provide an anti-obesity composition further comprising it. Furthermore, effective usage was confirmed.

In the case of Goryanggang extract, it showed a similar level of inhibitory effect on the growth of pre-adipocytes to that of Garcinia cambogia extract, a health functional food ingredient that has been recognized for its ability to inhibit body fat accumulation. In the case of bamboo leaves used in the present invention, although there are some effects, it did not show a satisfactory level of effect. However, when goryanggang extract and bamboo leaf extract were used together, the effect was much better than that of Garcinia cambogia extract. The effect of inhibiting the growth of differentiated adipocytes also showed similar results, and similar results were also shown in actual animal experiments.

Bamboo leaves are dried leaves of Chamdae, Phyllostachys bambusoides Siebold & Zucc. Chamdae grows in the south central part of our country. In summer, the green leaves are picked and dried in a well-ventilated shade. The taste is bitter and the nature is cold. It works on the heart, menopause, stomach, and liver. Relieves fever, relieves chest tightness, removes phlegm, and soothes cramps. It is used for fever, chest tightness, and thirst, for vomiting with stomach fever, coughing with sputum, colds of breath, spasms, laryngitis, and tongue ulcers.

Based on 100 parts by weight of the goryanggang extract, bamboo leaves can be used within the range of 50 to 150 parts by weight. If used too little, the synergistic efficiency is not good, and if used too much, the effect does not increase proportionally. The preferred amount was 100 parts by weight, and it was effective to use it in a similar specific gravity.

On the other hand, the present inventors paid attention to fenugreek and gilgyeong from the point of view of oriental medicine, and tried to select them and experiment. Although fenugreek and gilkyung were not effective in their anti-obesity effect, when used together, fenugreek and gilkyung showed their own meaningful effects. In the case of fenugreek and gilgyeong, as a secondary synergistic material, it is appropriate to use about half of the goryanggang extract. Fenugreek and gilgyeong may be used in an amount of 25 to 75 parts by weight based on 100 parts by weight of the goryanggang extract, more preferably about 50 parts by weight. When used too little, the auxiliary synergistic effect is not large, and the effect does not increase proportionally even if used more than necessary.

The scientific name of Fenugreek (胡蘆巴, Trigonellae Semen) is Trigonella foenum-graecum L, which is also called Fenugreek. The country of origin is India, China, Southeast Asia, Europe, Egypt, Sudan, the United States, Lebanon, and Argentine. Fenugreek seeds are usually dried in the sun and used for medicinal purposes. Fenugreek is warm in nature and non-toxic, so it has been used for bladder and kidney diseases since ancient times in Africa, the Middle East, and India, and is also used to treat people with cold sweats or a cold. It is said to cure sore throat, sore knees, damp scrotum, eliminate all 虛寒證 and numbness, treat frequent urination, and treat cold stomach symptoms. Recently, it has been reported that it is effective in maintaining the balance of blood sugar and insulin in the body, so research is being actively conducted.

Gilgyeong is a medicinal material made by removing the root or bark of the bellflower ( Platycodon grandiflorum A. De Candolle) of the bellflower family. This medicine has a slight odor, and the taste is bitter and bitter, and its properties are not biased toward either side. Gilkyung acts on the lungs to treat symptoms of difficulty in breathing with a lot of seawater and sputum, clears the lungs, relieves a stuffy chest, releases cold energy in the stomach, stops coughing and removes phlegm. It is also used when there is general edema due to inability to urinate and the amount of urine is small. It is used for sore throat, cough due to cold, phlegm, nasal congestion, asthma, bronchitis, pleurisy, headache, chills, and tonsillitis. As pharmacological action, expectorant action, blood sugar lowering action, cholesterol lowering action, and antibacterial action were reported.

The shape is irregularly thin and long spindle-shaped or conical, sometimes branched, and the outer surface is gray-brown, light brown or white. A straight root has a concave mark at the top end of which the stem has been removed, and there are thin horizontal folds and vertical grooves near it, and some are slightly bent. Most of the roots except for the upper part have rough vertical folds and horizontal grooves, and there are horizontal lines in the shape of bark. The quality is firm but easy to break. Broken sides are not fibrous and sometimes have large gaps. Other names are Gil Kyung-geun (桔梗根), Gyeongcho (梗草), Kogyeong (苦梗), Ko Gil-gyeong (苦桔梗), Li Yeo (利如), Bangdo (房圖), Baekyak (白藥), and Fubu (符扈). etc.

The core composition of the present invention is a combination of goryanggang and bamboo leaves. Their combination synergizes the anti-obesity effect. On the other hand, when fenugreek and gilgyeong were used together and added, they showed a very good effect. In the case of koryanggang, a core active ingredient, the actual effect was more excellent when administered at a dose of 3 to 9 mg/kg based on the goryanggang extract.

Meanwhile, in the present invention, the term “extract” refers to an active ingredient separated from a natural product. The extract can be obtained by an extraction process using water, an organic solvent, or a mixed solvent thereof, and includes an extract, a dry powder thereof, or any form formulated using the same. In the present invention, the gilgyeong extract may be extracted using water, an organic solvent, or a mixed solvent thereof. Preferably, it is an extract soluble in a lower alcohol having 1 to 4 carbon atoms or a mixed solvent thereof, and it is particularly preferable to extract using ethanol. The extracted liquid may be used directly or concentrated and/or dried. In case of extraction using an organic solvent, methanol, ethanol, isopropanol, butanol, ethylene, acetone, hexane, ether, chloroform, ethyl acetate, butyl acetate, dichloromethane, N, N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), 1,3-butylene glycol, propylene glycol, or an organic solvent that is a mixed solvent thereof is used, and extraction can be performed at room temperature or by heating under conditions in which the active ingredient of the herbal medicine is not destroyed or minimized. Depending on the organic solvent to be extracted, the degree of extraction and loss of the active ingredient of the drug may be different, so an appropriate organic solvent should be selected and used. The extraction method is not particularly limited, and examples thereof include cold extraction, ultrasonic extraction, and reflux cooling extraction. Filtration is a process of removing suspended solid particles from the extract, and may use cotton, nylon, etc. to filter out particles, ultrafiltration, cryofiltration, centrifugation, etc., but is not limited thereto. Methods such as reduced pressure concentration, reverse osmosis concentration, etc. may be used for concentration of the extract. The drying step after concentration includes, but is not limited to, freeze drying, vacuum drying, hot air drying, spray drying, reduced pressure drying, foam drying, high frequency drying, infrared drying, and the like. In some cases, a process of pulverizing the final dried extract may be added. In addition, the extract may be subjected to an additional fractionation process.

Hereinafter, the present invention will be described in more detail through Examples and Test Examples. However, these examples and the like are used for the purpose of illustration to help the understanding of the present invention, and the scope and scope of the present invention is not limited thereto.

<Example 1>

2 kg of goryanggang purchased from the Seoul Pharmacy Store was dried and pulverized in the shade and at room temperature for 5 days. The pulverized charzugi was immersed in 30 ℓ of 40% alcohol (ethanol) and extracted at 50° C. for 24 hours. This was filtered through filter paper, dried under reduced pressure, and concentrated to obtain 310 g of a total extract.

<Example 2>

Using 2 kg of bamboo leaves purchased from Seoul Pharmacopoeia, extraction was performed in the same manner as in Example 1 to obtain a total extract of 290 g.

<Example 3>

It was extracted in the same way using 3 kg of fenugreek purchased from Seoul Pharmacy Store, to obtain a total extract of 530 g.

<Example 10>

With respect to Example 5, the composition was composed in a ratio of 50 parts by weight of fenugreek of Example 3 and 50 parts by weight of Gilgyeong extract of Example 4 based on 100 parts by weight of the goryanggang extract.

<Toxicity evaluation>

MTT analysis was performed to confirm the effect of the Examples on the viability of 3T3-L1 preadipocytes. 3T3-L1 preadipocytes were seeded in 96-well plates at a concentration of 1Х10 ⁵ cells/ml. Thereafter, the cells differentiated through differentiation induction were treated with DW in Examples and a negative control at a concentration of 50 to 250 ppm and cultured for 2 days. After 2 days, the medium was replaced with a medium containing 0.5 mg/ml of MTT reagent and cultured for 1 hour. After that, the medium was discarded and 100 μl of DMSO was dispensed to dissolve the generated formazan, and absorbance was measured at a wavelength of 540 nm.

At all concentrations, there was no significant difference compared to the negative control group, so it was judged that cytotoxicity was not a problem.

<Experiment to inhibit growth of preadipocytes>

3T3-L1 preadipocytes were incubated in a 96-well plate at a density of 1x10 ⁴ cells/ml. Except for the negative control (DMSO solvent control), Garcinia cambogia extract (positive control) and Examples were treated in the cells at a concentration of 100 ppm. It was repeated three times for each group and the average value was used. Garcinia cambogia extract is a health functional food ingredient that has been recognized for its ability to inhibit body fat accumulation. After administration and incubation for 48 hours, the cell growth status was recorded, and the growth inhibitory effect of each test substance on 3T3-L1 preadipocytes was analyzed by MTT analysis.

The results are shown in FIG. 1 compared to the control group. Although the garcinia cambogia extract, which is a positive control, did not show a better result than the garcinia cambogia extract, it showed an almost similar effect. Bamboo leaf, fenugreek, and gilgyeong themselves had some effect, but did not show significant results. However, in the case of Example 5, which is a combination of goryanggang and bamboo leaves, it showed a superior effect than the positive control, confirming the synergistic effect of these combinations. And, even when fenugreek and gilkyung were added individually to these combinations, no significant change was shown, however, Example 10, in which fenugreek and gilkyung were added together, showed the best results.

<Experiment to inhibit the growth of differentiated adipocytes>

3T3-L1 cells were incubated in 12-well plates at a density of 1× ^{10 5} cells/well. 3T3-L1 preadipocytes were cultured in a medium containing 10% BCS and 1% P/S, and the culture environment was maintained at 37°C and 5% carbon dioxide. Two days after cell confluency was reached (Day 0), it was replaced with a differentiation induction medium containing 5 μg/ml insulin, 1 dexamethasone, 0.5 mM IBMX, and 10% FBS. From Day 2, the medium containing only 5 μg/ml insulin and 10% FBS was replaced, and the medium was replaced with a new medium every two days and cultured for 8 days. Cells were treated with the extract from Day 0, and the final concentration of cells treated was 250 ppm based on the concentration of chazugi.

The results are shown in FIG. 2 compared to the control group. Although the garcinia cambogia extract, which is a positive control, did not show a better result, the goryanggang extract showed a relatively similar effect, confirming that the garcinia cambogia extract had a significant meaning. As in Example 5, when goryanggang and bamboo leaves were used together, and when goryanggang, bamboo leaves, fenugreek, and gilkyung were used together as in Example 10, excellent effects were shown. Overall, it showed a trend similar to the results of the preadipocyte growth inhibition experiment.

<Experiment of weight change after induction of obesity>

In this experiment, 8-week-old female B6 mice were used. In this experiment, it was divided into a normal control group, an obese control group, and a group administered with the extract of Example, respectively. This experiment was performed using 5 female mice in each group. During the experimental period, with the exception of mice in the normal control group fed a normal-fat diet, other groups of mice were continuously fed a high-fat diet for 8 weeks to induce obesity. At the same time, the test substance was orally administered daily for 8 weeks. Reflecting the results obtained through the preadipocyte growth inhibition experiment and the differentiated adipocyte growth inhibition experiment, the garcinia cambogia extract was used as a positive control group, and it was verified whether the combination of Examples 1, 5, and 10 was effective. Differences in body weight and body fat between mice in groups were evaluated, and the body weight and average food intake of each animal were recorded weekly for the duration of the experiment.

The final weight change is shown in FIG. 3 . The normal control group showed an increase in body weight of 9 g, and the obese control group fed a high-fat diet increased the body weight by 33.5 g. When Garcinia cambogia extract, which is a positive control, was administered, a weight gain of 14.8 g was shown, showing that there was an anti-obesity effect. On the other hand, in the case of Example 1, the effect was somewhat lower than that of the positive control group, but showed an effect similar to that. In the case of Example 5 and Example 10, it showed an effect superior to the positive control group. Example 10 showed a similar level of effect to the normal control group.

<Changes in blood biochemical indicators>

Fasting (water is supplied) for at least 16 hours before and 8 weeks after the start of the animal experiment, and then primary anesthesia through isoflurane (Baxter, USA) inhalation, and then fasting blood is collected from the inferior vena cava total cholesterol (Total-cholesterol; Total-C), triglyceride (TG), free fatty acid (FFA), high-density lipoprotein-cholesterol (HDL-cholesterol; HDL-C), And the amount of non-high-density lipoprotein-cholesterol (nonHDL-cholesterol; nonHDL-C) was measured. The content of all five lipids was increased in the obese control group compared to the normal control group. In the case of the positive control group, the contents of TG, Total-C and FFA were slightly decreased compared to the obese control group, but did not show much difference, HDL-C showed a similar level, and the content of nonHDL-C was significantly decreased. did. On the contrary, in the case of Example 5 and Example 10 of the present invention, overall excellent results were shown.

<Sensory evaluation>

Since the composition of the present invention is a safe material that can be used as a food composition, weight measurement and subjective feeling (fatigue, defecation effect) were evaluated for 25 adult males and 25 adult females (40s to 50s). 5 adult males and 5 adult females were assigned to each of the compositions of placebo, Garcinia cambogia extract, Example 1, Example 5, and Example 10. Those of Examples 5 and 10 showed higher satisfaction than the Garcinia cambogia extract used as a positive control.
