Description

Composition comprising the extract of Coptidis Rhizoma for preventing and treating respiratory organ disease}

The present invention relates to the expectorant activity, antitussive activity and antihistamine activity effect of the extract of the yellow lotus, provides a composition useful for the prevention and treatment of antitussive, expectorant or respiratory diseases containing the extract as an active ingredient.

The respiratory system of our body is one of the organs that constantly defends against physical and chemical stimuli. When the stimulant enters the respiratory tract, most of the stimulant gets caught in the nose and does not enter the respiratory tract, but the fine stimulant passed through it is surrounded by mucus, The tiny cilia located on the airway wall send them out or up, which is the basic principle of coughing. Cough, as mentioned earlier, is a reflexive defense mechanism caused by airway mucosal stimulation, and when a persistent cough is caused by excessive stimulation, it reduces and worsens the quality of life of the patient. In the same principle as coughing, when dust or irritants are introduced from the outside, the body's bronchus moves muscles with saliva and pushes them to the outside. Will be.

As a result, cough and sputum are caused by physical and chemical factors such as cold air, external foreign substances, including pathogenic microorganisms, air pollutants, and allergens, which can be divided into three categories.

First, stimulation of cough receptors in the larynx, trachea, bronchus, pharynx, sinuses, diaphragm due to physical and chemical factors, the stimulus is transmitted to the cough center of the soft zone of the brain and cough reflex occurs. The mechanisms of antitussives, which are closely related to these irritant cough reflexes, are classified into central and peripheral, and the mechanisms of central antitussives are drugs that control cough by inhibiting the relieving center of soft water, such as codeine and dextromethorphan ( dextromethorphan, noscapine, ephedrine, zipeprol, etc. These components often cause side effects such as cardiovascular thrombosis, myocardial infarction, respiratory depression, sedation, and gastrointestinal disorders. There is. Peripheral antitussives act on the kidney's kidney receptor (stretch receptor) to control cough, which is relatively safe to compensate for the disadvantages of central antitussives, and the development of such antitussives has recently been tried a number of representative drugs Levopropizine, benzonatate, benzozaine, benzyl alcohol, and the like are used.

Second, when the parasympathetic nervous system is activated due to physico-chemical factors, bronchial smooth muscle contracts and thus symptoms such as bronchial spasms and bronchial contractions may occur. At this time, the beta 2 agonist stimulates the beta 2 receptor to relax the smooth muscle, and the xanthine derivative increases cAMP or inhibits bronchial smooth muscle by inhibition of phosphodiesterase. It acts as a direct relaxation, increasing mucus secretion while dissolving mucus and promoting ciliary movement. Drugs exhibiting this action include beta 2 agonists such as clenbuterol, bambuterol and formoterol, and xanthine derivatives such as theophylline and aminophylline. aminophylline), acepiphylline (acepifylline), bamifylline and the like.

In addition, there is a mucus solubilizer or expectorant that dissolves the produced mucus to reduce viscosity and promote bronchial cilia, thereby promoting sputum discharge. Airway mucus has several important functions in prayer. That is, it protects the airway from particles entering the airway from the outside, maintains the humidity of the intake air, and serves to remove the inhaled chemicals and gases by binding to the mucus protein, cilia. Mucus also has substances that play an important role in immune function, such as immunoglobulin A (IgA), lysozyme, lactoferrin, and the like. Most expectorants have been used as folk medicines or experience prescriptions for thousands of years using plants, and the compounds include cysteine derivatives such as carbocysteine, N-acetylcysteine, and cysteine ethyl ester hydrochloride. Is being used. The above-mentioned cysteine derivatives are not completely satisfactory when used as an expectorant, and in particular, N-acetyl cysteine and cysteine ethyl ester hydrochloride have both high toxicity and chemical instability. Therefore, the development of expectorants with good physical and chemical stability and less side effects, toxicity and good expectorant effects has been required.

Recently, research on antitussive expectorants derived from natural products has been actively conducted. Representative studies related to this include stimulating the vagus nerve of the airway to promote secretion of the mucosa, expressing expectoration and at the same time, n-supplementary role of antitussive action. There are also reports of plants containing saponins, alkaloids, etc. (Sook Young Kim et al . , Kor . J. Pharmacogn . 19 (2): 133-140, 1998).

Third, inflammatory mediators are released from mast cells due to physical and chemical factors. Mast cells contain small cytoplasmic granules containing inflammatory mediators such as histamine and cytokines. When exposed to an allergen, the body produces an antibody called IgE in B cells, which attaches to the surface of mast cells. Subsequent exposure to allergens causes the release of allergens, including histamine, a potent inflammatory mediator, from IgE-attached mast cells, resulting in increased secretions in the airways, effusions from inflammation, inhaled foreign bodies, and bacteria. Leads to. Existing drugs such as codeine, widely used as antitussives, have excellent sedative effects on breathing and coughing, but have side effects that release histamine by causing degranulation of mast cells.

In addition, based on the above description, the mechanism and function closely related to antitussive expectoration, antibacterial action to enable the removal of the causative agent and prevention of secondary infection, anti-inflammatory action to inhibit the synthesis of inflammatory mediators, histamine from mast cells Antihistamine activity that inhibits secretion, antioxidant activity that prevents inflammation and tissue damage, elastase activity release that releases inflammatory mediators from immune cells, hyaluronidase activity involved in vascular permeable inflammatory reactions Inhibition, etc. will be a function that requires.

Thus, the present inventors have completed the present invention by confirming that the extract of the antitussive or expectorant is excellent in the antitussive, expectorant and antihistamine activity effects.

In order to carry out the above object, the present invention provides a composition for antitussive or expectorant containing sulfur extract as an active ingredient.

Herbal medicine (Coptidis Rhizoma), a herb used in the present invention, is a perennial herb belonging to Ranunculus family. The rhizome is called Hunan, yellow, branched, and beard roots are dense. It has been known to have pharmacological effects such as antimicrobial action, blood pressure lowering action and anti-inflammatory action. In oriental medicine, it is used as a gastric agent, central nervous system agent, uterus, bladder, bronchial and nervous system agents. It is known to contain alkaloids such as berebrine, palmatine, coptisine, berberastine, magnoflorine, etc. , Dohae Hyangdae (Medicinal Herbs), 490-493, 1990).

However, the effects of these extracts and components on antitussive, expectorant and antihistamine activities have not been studied.

'Extract' as defined herein is characterized in that the crude extract of the yellow lotus or a polar solvent soluble extract of the crude extract.

The crude extract as defined herein is a solvent selected from water, including purified water, straight-chain or branched alcohols having 1 to 6 carbon atoms or mixed solvents thereof, preferably water, 10-70% (v / v) aqueous ethanol solution or water. It is characterized by a saturated butyl alcohol.

The polar solvent soluble extract as defined herein is characterized in that the linear or branched alcohol having 1 to 6 carbon atoms, preferably saturated butyl alcohol, and the fraction is the methylene chloride and methanol (30: 1 to 7). : 1 (v / v)) is a mixed solvent, characterized in that the fraction obtained by performing silica gel column chromatography .

The rhubarb extract or fraction of the present invention is characterized in that it contains berberine, palmin, copticin, columamine and jathrorizine, preferably berberine (0.5 to 47.0 parts by weight): palmin (0.2 to 21.4 parts by weight) ): Copticin (0.1 to 18.0 parts by weight): columamine (0.1 to 3.2 parts by weight): jatrorizine (0.1 to 2.6 parts by weight) characterized in that it comprises within the range.

Hereinafter, the method for obtaining the crude extract, the polar solvent soluble extract or fraction of the crude extract of the present invention will be described in detail.

The crude extract of the yellow rye of the present invention is chopped the dried yellow rye, about 3 to 20 times the weight (kg), preferably about 5 to 15 times the water, C ₁ to C ₆ linear or branched alcohol Or a mixed solvent thereof, preferably water, 10-70% (v / v) aqueous ethanol solution or saturated butyl alcohol, at an extraction temperature of 40 ° C to 110 ° C, preferably 55 ° C to 90 ° C. The crude extract of the present invention may be obtained by filtration, concentration under reduced pressure, or drying the extract obtained by using cold soaking, hot water extraction, ultrasonic extraction, reflux cooling extraction for 20 hours, preferably about 1 to 10 hours.

The crude extract was filtered to collect the filtrate, and the residue was added with 4-7 times the weight of the crude drug raw material water, an aqueous alcohol solution or a saturated butyl alcohol, and warmed again to extract for 2-5 hours, filtered and mixed with the previous filtrate. Increase the extraction efficiency If the amount of solvent is too small, the stirring becomes difficult and the solubility of the extract is low, the extraction efficiency is lowered. If the amount is too large, the amount of lower alcohol used in the next purification step is increased, which is not economical and may cause handling problems. . In the present invention, the method of re-extracting after the first extraction is adopted. Even in the case of mass production of the herbal extracts, even though the filtration is effective, the loss occurs because the water content of the herbal medicine itself is high, so the extraction efficiency is reduced only by the first extraction. This is to prevent this. In addition, as a result of verifying the extraction efficiency of each step, it was found that about 80 to 90% of the total extraction amount is extracted by the second extraction, and the third or more multi-stage extraction is not economical.

In addition, the polar solvent soluble extract of the present invention is suspended in the crude extract of about 2 to 10 times, preferably about 3 to 7 times the volume of water, the polar solvent such as saturated butyl alcohol 0.5 to 3 times of the suspension, It is preferably prepared by adding the same amount to 2 times and extracting the polar solvent soluble layer for 1 to 5 times, preferably 2 to 3 times, followed by concentration under reduced pressure.

The lower alcohol fraction obtained after layer separation is concentrated under reduced pressure at 50-60 ° C. to remove the solvent remaining in the sample. The concentrate thus obtained is azeotropically concentrated two to three times with water 25 to 50 times the total amount of the concentrate, and suspended again in an equal amount of water. The reason for azeotropic concentration with water at the time of the concentrated drying is to effectively control the content of the lower alcohol remaining in order to use the obtained herbal extract as a raw material for pharmaceuticals.

As described above, the extract obtained by extraction with water, C ₁ to C ₆ straight chain or branched alcohol, or a mixed solvent thereof is filtered and concentrated, and then unnecessary proteins, polysaccharides and fatty acids contained in the filtrate. In the present invention, impurities are purified by performing a layer separation two to four times with the filtrate and the same amount of lower alcohol to obtain a solvent fraction. In this case, as the lower alcohol, alcohol having 1 to 6 carbon atoms, preferably butyl alcohol, propyl alcohol or isopropyl alcohol, and when the amount of lower alcohol is less than the filtrate, fine particles are formed by unnecessary components such as fatty acids. Therefore, the separation of the layers is not smooth and the extraction content of the active ingredient is lowered, which is not efficient.

In addition, the sulfur extract obtained in the above was mixed with methylene chloride and methanol (30: 1-7: 1 (v / v)), and subjected to silica gel column chromatography, divided into five subfractions to obtain physiology for each fraction. By conducting an activity experiment, active fractions and components were identified.

As a result of analyzing the components of the extract and fractions of the present invention, it was confirmed that berberine, palmatin, copticin, columamine, and jathrorizine are included.

Accordingly, another aspect of the present invention is directed to a composition for the prevention or treatment of antitussive, expectorant or respiratory diseases containing at least one selected from the group consisting of berberine, palminth, copticin, columamine, and jathrorizine as an active ingredient.
