Description

Method for extracting ellagic acid and myrobalan acid from myrobalan and composition thereof
Technical Field
The invention relates to the field of traditional Chinese medicine extracts, and in particular relates to an extraction method of ellagic acid and myrobalamin acid in myrobalan and a composition thereof.
Background
With the rapid development of economy, the dietary structure and habits of people are greatly changed, and many people have excessive energy intake while having gulosity meals, so that the so-called 'rich diseases' represented by hypertension and hyperlipidemia are followed. Hypertension and hyperlipidemia are the sources of many diseases, and with high-fat and high-salt diet and unreasonable diet habits, human metabolism is disordered. Hyperlipidemia can cause blood lipid increase, and is a risk factor for stroke, coronary heart disease, myocardial infarction and sudden death. In addition, hyperlipidemia is also an important risk factor for the promotion of hyperlipidemia, impaired glucose tolerance, and diabetes. Hyperlipidemia can also lead to fatty liver, liver cirrhosis, cholelithiasis, pancreatitis, fundus hemorrhage, blindness, peripheral vascular disease, claudication, and hyperuricemia. Therefore, the harm of hyperlipidemia must be paid high attention to, and active prevention and conditioning are required. High salt easily induces hypertension, the disease generally has slow onset, the early stage of a patient often has no symptoms, or only has symptoms such as dizziness, headache, palpitation, tinnitus and the like, the disease is seemingly an independent disease, and is actually an important risk factor for causing heart, cerebral vessels and kidney diseases, and if the treatment is improper, the disease becomes serious common hypertension complications such as cerebral apoplexy, myocardial infarction, renal failure and the like.
Western medicines are mainly used for treating three highs, and hypertension and hyperlipidemia can be effectively controlled. However, western medicines often cause some adverse reactions while being effectively adjusted, such as: the diuretic antihypertensive medicine has the main side effects of hypokalemia and hyperlipidemia (blood fat, blood sugar and blood uric acid). Drug side effects have become one of the important problems affecting long-term sustained treatment and quality of life and must be properly recognized and properly managed.
In recent years, the research on myrobalan in the field of traditional Chinese medicine has further progressed, and the extracted effective substances ellagic acid and myrobalan acid have good effects of reducing three highs, diminishing inflammation, improving eyesight and strengthening heart. Modern pharmacological research shows that the myrobalan has various pharmacological effects of neuroprotection, oxidation resistance, cardiotonic, antibacterial, anti-tumor, hypertension, hyperglycemia, hyperlipidemia and the like.

Theoretical basis:
safflower, also called as safflower and thorn safflower, is of Compositae and safflower, has the functions of promoting blood circulation and stimulating the menstrual flow, removing blood stasis and relieving pain, and is helpful for treating amenorrhea, dysmenorrhea, lochiorrhea, thoracic obstruction and pain, stasis and abdominal pain, stabbing pain in chest and hypochondrium, traumatic injury and sore and ulcer swelling and pain. Has the effects of promoting blood circulation, removing blood stasis, eliminating dampness and swelling, and can be used for preventing pregnant women from abortion.
The efficacy of safflower is:
1. inhibition of cardiac action: the small dosage of the safflower decoction can cause the in vitro heart of the toad and the heart of the rabbit in vivo to be slightly excited, so that the heartbeat is powerful and the amplitude is increased; the large dosage can inhibit heart, slow heart rate, weaken myocardial contractility, and reduce cardiac output.
2. Experimental studies on coronary blood flow indicate that: the water extract and water-soluble mixture of Carthami flos, HONGHUAHUASU, have the effects of increasing coronary blood flow and myocardial nutritional blood flow; the functions of expanding coronary artery and increasing coronary blood flow of the ethanol extract of safflower are not obvious or have no influence.
3. Experimental studies on experimental myocardial ischemia and myocardial infarction showed that: safflower and its preparation have different degrees of antagonistic action on animal models of rabbit, rat, dog, etc. causing experimental myocardial ischemia or myocardial infarction. The safflower can obviously protect the acute myocardial ischemia of rats or rabbits caused by the pituitrin; the method can obviously reduce the degree of acute myocardial ischemia of the anesthetized dog caused by repeated and transient blockage of coronary artery blood flow, reduce the range and slow the heart rate, protect the edge of an acute myocardial infarction area, narrow the infarction range and reduce the elevation amplitude of the electrocardiogram ST section at the edge area, thereby improving the supply and demand relationship of ischemic myocardial oxygen.
4. The research on the effect of the safflower on blood vessels finds that: for example, the blood vessel is perfused by Rockwell fluid containing trace adrenaline or noradrenaline, so that the smooth muscle of the isolated blood vessel of the animal is contracted to keep certain blood vessel tension, and the blood vessel obstruction and blood stasis state which may be similar to that of people are caused. Safflower can make the hind limb and rabbit ear of guinea pig with increased tension show vasodilatation, and has obvious effect with increasing dosage, and safflower can also increase blood flow of anesthetic dog femoral artery, but can contract normal isolated blood vessel of toad and rabbit. The safflower vasodilatation effect is related to the functional state of blood vessels and the dosage of the medicine. The mechanism of action may be mainly vasodilatation, directly or partially against the action of alpha-adrenergic receptors, with weaker direct vasoconstrictive action.
5. Influence of safflower on cerebral edema caused by ischemic stroke of experimental animals: applying a safflower injection (1ml contains 1g of crude drug), performing preoperative 30 minutes for 63 Mongolian gerbils and ip administering to 10g/kg of the safflower injection, establishing an operation control group and a pseudo-operation group, observing the influence of safflower on ischemic cerebral edema, and researching the change of the content of monoamine neurone in the same brain area. The results suggest that the mechanism by which safflower relieves ischemic cerebral edema may be associated with metabolic disorders that affect monoamine neurotransmitters in tissues. Further proves that safflower can actually reduce the incidence rate and the death rate of cerebral apoplexy and has a protective effect on the brain tissue of experimental animals with the thoracic infarction.
6. The function of reducing blood pressure: the safflower decoction, safflower yellow and other preparations have different degrees of rapid blood pressure reduction effects on anesthetized cats or dogs, the average blood pressure is reduced by about 20 mm Hg, and the recovery is realized after about 30 minutes.
7. Relieving pain and tranquilizing.
8. Has anti-inflammatory effect.
The efficacy of myrobalan:
myrobalan has the effects of relieving diarrhea with astringents, astringing lung to relieve cough, reducing pathogenic fire and relieving sore throat. It is commonly used for chronic diarrhea and dysentery, hematochezia and rectocele, cough and dyspnea due to lung deficiency, chronic cough, pharyngalgia and hoarseness.
The myrobalan has strong detoxification efficacy, not only can remove endogenous toxicosis caused by pathogenic qi gathering in the chest of a zang and zhuang chest, but also can remove exogenous toxicosis caused by food poisoning drugs, snake bite and the like. The water decoction of myrobalan has strong gonococcus resisting effect in vitro. The alcohol extract of fructus Chebulae has the effect of enhancing the contractile function and excitability of the atrial muscle. The myrobalan alcohol extract can shorten the effective refractory period of the left atrial muscle, reduce the maximum driving frequency of the left atrial muscle and improve the excitability of left atrial muscle cells.
The efficacy of gardenia:
fructus Gardeniae is also called as fructus Gardeniae, and Bufo bufo gargarizans, and has effects in protecting liver, promoting bile flow, lowering blood pressure, tranquilizing mind, stopping bleeding, and relieving swelling. Is used for treating icteric hepatitis, sprain, contusion, hypertension, diabetes and other diseases in traditional Chinese medicine clinic. The gardenia yellow wine has the health-care function, is a natural plant pigment integrating the functions of coloring, nutrition and health care, has the functions of clearing heat, removing fire, cooling blood, benefiting gallbladder and reducing cholesterol, and has certain health-care function.
