Anti-fatigue and tonic agent containing wild ginseng

TECHNICAL FIELD

[0001] The present invention relates to an anti-fatigue and tonic agent containing wild ginseng. More specifically, the present invention relates to an anti-fatigue and nutritious tonic agent containing powder of wild ginseng, mixed powder of wild ginseng and herb medicine, or water extract of the powder, as the active ingredient, and to a process for preparing the same.

BACKGROUND ART

[0002] Wild ginseng is classified into natural wild ginseng, woods grown ginseng, and wild stimulated ginseng. Natural wild ginseng is naturally growing ginseng in deep mountains. Before the beginning of cultivation of ginseng in Korea, wild ginseng has been gathered and used. However, due to an increasing demand on wild ginseng, resources for wild ginseng have been exhausted and gathering wild ginseng in the nature has become very difficult. Therefore, such a demand could not be satisfied, and thus, cultivating ginseng was tried. From the beginning of cultivation of ginseng, cultivation technologies have been continuously developed. Further, ginseng cultivators have continued to choose individual species of ginseng having superior characteristics and quantities of roots, intentionally or customarily. Both of Korea ginseng currently cultivated and wild ginseng fall within the same species, Panax ginseng. However, cultivated ginseng can be remarkably distinguished from wild ginseng not only in the growth rate but also in morphologies of stem and leaf, and root. Such a distinction resulted from selection of individual species continuously carried out for a long period of time since the cultivation of ginseng was begun. Differences between wild ginseng and cultivated ginseng are as follows. FIGS. 1 and 2 show schematic appearances of wild ginseng and cultivated ginseng, respectively. As shown in the Figures, wild ginseng has slim and long rhizome (1), which is formed one a year; slim and long main root (2) having flavor, the more of which is the better; hard fine roots (3) having high tensile strength; and nodule (on fine roots) (4), which is similar to nodosity. It is gold-colored, tastes sweet and bitter and has flavor. In comparison, cultivated ginseng has short 1-2 layered rhizome (1′); short thick main root (2′); many white fine roots (3′), which are weak and thus, easily torn apart. It has bitter and sweet taste, but no flavor like wild ginseng.

[0003] Main chemical ingredients of ginseng are alkaloids, saccharides, organic acids, lipophilic ingredients, nitrogen-containing compounds, vitamins and inorganic ingredients including glycoside (saponins). The most important ingredients for pharmacological effects of ginseng are saponins, and alkaloids whose activity has not yet been clearly verified. A number of kinds of saponins are contained in ginseng, whose representative example is ginsenoside Rb1. Ginsenoside Rb1 has various pharmacological effects: e.g. control of central nerve system; hypnotic, analgesic, sedative and antipyretic effects; stimulation of synthesis of serum proteins; inhibition of degradation of neutral fats, or stimulation of synthesis thereof (insulin-like effect); stimulation of biosynthesis of cholesterol; stimulation of synthesis of RNA; stimulation of secretion of adrenal cortical hormone; improvement of learning memory; and inhibition of eating. Panax ginseng C. A. Meyer has been reported to have effects of nutrition and tonic, excitation of nerve system, stimulation of secretion of adrenal cortical hormone, promotion of sexual functions, heart tonic, decrease in blood glucose, improvement of appetite, anti-anaphylaxis, anti-diuretic, anti-stress, anti-fatigue, promotion of recovery from fatigue, reinforcement of immune functions, etc. However, such pharmacological effects are complex and various, not by a single ingredient.

[0004] In contrast, wild ginseng's pharmacological effects have not yet been identified, but is expected to have similar effects to those of cultivated ginseng.

[0005] Lycii Fructus is known to have effects of nutrition and tonic, promotion of regeneration of liver cells, improvement of liver functions, and clearance of eyes. Cnidii rhizoma has an anti-blood stagnation effect, and thus, is used for sedation, the therapy of anemia and headache. Angelicae gigantis Radix has effects of complementation of blood and tonic, and activation of blood, and thus, is used for therapy of woman diseases from blood circulation disorders. Therefore, a mixture of the above ingredients has a high calorie and effects as a heath supplement, which has not yet been experimentally verified. Particularly, ginseng has been extensively studied for its ingredients. However, because wild ginseng (natural wild ginseng), distinguished from cultivated ginseng, is very expensive and has limited quantities, it has not yet been sufficiently studied for its ingredients. Moreover, a composition or formulation containing wild ginseng as a principal agent has never been developed, since wild ginseng has been taken raw or in a soup boiled down. That is, a nutritious tonic agent containing wild ginseng as a principal agent has never been manufactured and marketed.

[0006] On the other hand, the physiological and biochemical mechanism by which the body feels fatigue has been already known. Some known methods for evaluating fatigue are “Forced Swimming Test”, measuring swimming and rest times in animals, and “Stimulation Unit of Activity (SUA33) Test” expressed as a dose of compound needed to extend the period of time of motion by 33%, in the time of walking on a rope. However, the above methods are not desirable experimental models because of large variations among individual animals. Therefore, it has been needed to construct a new model for measurement of an anti-fatigue effect.

DISCLOSURE OF THE INVENTION

[0007] The present inventors performed extensive studies to develop a new agent having superior anti-fatigue and nutritious tonic effects than the known agents. As a result, the inventors formulated a composition containing powder of wild ginseng, instead of cultivated ginseng, optionally in admixture with a herb medicine, or water extract of the powder. The inventors then measured its pharmacological efficacy by analysis of the contents of total saponin and ginsenoside Rb1 for comparison. In addition, the inventors improved the prior measurement method of an anti-fatigue effect, and developed “4% weight-loaded swimming test” measuring the swimming time under a certain load to the body weight of an animal, whereby the anti-fatigue effect was evaluated, and so completed the present invention.

[0008] Therefore, an object of the present invention is to provide a new anti-fatigue and nutritious tonic agent containing powder of wild ginseng or mixed powder of wild ginseng and herb medicine, or water extract of the powder, and a process for preparing the same.

[0009] One aspect of the present invention provides an anti-fatigue and nutritious tonic agent composition containing powder, obtained by powdering wild ginseng alone or by further mixing the obtained powder with powder of one or more herb medicines, conventionally used in nutritious tonic agents, as the active ingredient.

[0067] Experimental Animals and Breeding Condition

[0068] ICR mice of 18±5 g were bred in a breeding room of Sam Sung Pharmaceutical Ind. Co., Ltd. at a temperature of 23±2° C., relative humidity of 60±2%, and illumination of 12 hrs/day. The animals were put into a mouse cage and provided with feed and water ad libitum.

[0069] Method

[0070] 1) Measurement of an Anti-Fatigue Effect

[0071] Weight-loaded forced swimming test by Toshitsugu Moriura and David L., et al. was improved as follows. Because a normal mouse can swim for 30 minutes or more, it takes a long time to observe the swimming time and is difficult to determine the finish time of swimming. Therefore, a certain weight was loaded in proportion to the body weight of a mouse, and the finish time of swimming was defined at a point of time when the two eyes sink down the surface of water for 5 seconds or more. As a result, the swimming time was shortened in a weight-dependent way as set forth in the following Table 2.

19TABLE 2Load (weight %)The number of miceSwimming time (min)07>302720.31 ± 5.39*37 8.34 ± 2.29*47 1.10 ± 0.85*57 0.5 ± 0.06*The values are expressed as Mean ± S.D. *Weight-dependent compared with the Control (p < 0.001)

[0072] From the above Table 2, it was concluded that it was the most ideal to test an anti-fatigue efficacy under the load of 4% weight to a mouse.

[0073] Based on the above result, distilled water was filled in a transparent plastic square container of 15 cm×25 cm×20 cm with the height of 15 cm. While keeping the water temperature at 37° C., the swimming time was measured. The experimental animals had been fasted for 12 hours and then, weighed. The animals were allowed to swim while hanging a lead wire of the 4% weight to the body weight on the neck. The finish time of swimming was defined at the time when the mice settled down with the two eyes' sinking for 5 seconds. The experimental animals were divided into groups consisting of 7 animals, and administered for 1 to 7 days before experimentation. A test material was orally administered for 30 minutes before experimentation.

[0074] 2) Measurement of the Content of a Total Saponin

[0075] Samples of 1-2 g were added to 100 ml of water and transferred into a separatory funnel. Thereto was added 100 ml of ether, and the aqueous layer was extracted three times with 60 ml of water-saturated butanol. The combined extract was washed with 50 ml of water. The extract was dried and put into a weighed flask, and concentrated under reduced pressure (105° C., 20 minutes). Then, it was left to cool in a desiccator and weighed. The content of a total saponin was calculated by the following formula:

The content of a total saponin=(A−B)/S

[0076] S: The initial weight of a sample

[0077] A: The weight of a flask containing extract concentrated under reduced pressure and dried

[0078] B: The weight of a flask when decreased by 0.25% or less compared with that before drying for 1 hour.

[0079] 3) Measurement of Ginsenoside Rb1

[0080] Samples of 3 g were taken and introduced into 50 ml of methanol. The mixture was filtered and the filtrate of 3 ml was developed on a pre-activated sep-pak. The sep-pak was washed with 10 ml of water and 15 ml of methanol, and eluted with 10 ml of methanol. The eluted solution was used as a test material. The test material was analyzed by HPLC on C18 reverse-phase column (Luna 10μ) [Flow rate: 0.6 ml/min, Mobile phase: 20% acetonitrile, Detector: UV detector (205 nm)].

[0081] Results

[0082] 1) Anti-Fatigue Effect of Cultivated and Wild Ginseng Powder

[0083] Using the above 4% weight-loaded mice, swimming was started in 30 minutes from administration of a test material. The anti-fatigue effect of the test material was calculated by the following formula:

Anti-fatigue effect=Swimming time of the experimental group/Swimming time of the control group

[0084] The results are shown in FIG. 3. The values in FIG. 3 are Mean ±S.D. obtained from 7 mice and the symbol ** means to have a significance in p<0.01. As shown in FIG. 3, in case of administering wild ginseng powder for 4 days or more, a significantly improved anti-fatigue effect could be obtained compared with when administering cultivated ginseng powder.

[0085] 2) Analysis of the Content of a Total Saponin in Cultivated and Wild Ginseng Powder

[0086] The measurement results of the content of ginsenoside Rb1 in a sample are shown in FIG. 5. As shown in FIG. 5, the content of Rb1 showed a significant difference between cultivated and wild ginseng powder.

[0087] Conclusion and Discussion

[0088] In the Experimental group administered with wild ginseng, a significant anti-fatigue effect was obtained in 4 days after administration. In the group administered with cultivated ginseng, an anti-fatigue effect could also be obtained, but was not significant. In particular, wild ginseng contains total saponin by 2 times more and a significantly higher amount of ginsenoside Rb1, one of saponins, than cultivated ginseng. From such results, wild ginseng is contemplated to have much higher contents of saponins and alkaloids that are pharmacologically effective ingredients than cultivated ginseng.

INDUSTRIAL APPLICABILITY

[0089] The agent according to the present invention has much higher contents of ginseng saponins and alkaloids that are pharmacologically effective ingredients than that containing cultivated ginseng as a principal agent, and thus, exhibits excellent anti-fatigue, and nutrition and tonic effects.
