In Chinese poetry, there are many verses referring to the acacia flower, which are often used to express a kind of sadness and sorrow. In the Tang Dynasty, Luo Ye had a poem called "Acacia Flower", which reads, "Outside of the Palace Gate, the Stranger Copper Camel is planted on both sides of the river, which is the most. In the early fall, when the season is approaching, the golden stamens of the acacia blossoms are blooming towards the Guanhe River. The tower sends hate to float the pearl foil, steed pity fragrance shakes the jade ko. Sorrow kills the jianghu with the planner, year after year for you to run around" (from the "Tang Poetry" Volume 654-9), and other examples such as "curling autumn winds, acacia flowers half into the real" (Bai Juyi's "Autumn"), "in front of the house in the twilight, the acacia flowers are one inch deep! " (Bai Juyi's Leisurely Lying in the Autumn Cool), "Who lived here in the past? The ground was full of acacia blossoms and autumn grasses" (Zilan's "Searching for Pei Langzhong's Former Residence in Taipingfang"), and "The wind dances the acacia blossoms to fall down the royal ditch, and the color of the Final South Mountain enters the city in the autumn" (Zilan's "Early Autumn in Chang'an"). (Zilan, "Early Autumn in Chang'an"). Sophora flowers are sweet and fragrant, rich in vitamins and minerals, and also have the effect of clearing heat and detoxification, cooling the blood and moistening the lungs, lowering blood pressure, and preventing strokes. Will be picked after the soup can be made, mixed vegetables, stewed rice, can also do acacia cake, dumplings, daily life is the most common steamed acacia (also known as acacia wheat rice), many regions of China have this habit, the practice is very simple, will be cleaned acacia flowers into the flour mix, and then add refined salt, monosodium glutamate and other seasonings, mixing well into a cage drawer can be cooked by steaming. In addition, in the production of porridge, soup can also add acacia flowers. Although the acacia flower is delicious, but there are some contraindications when eating. Because of the sweet acacia flowers, diabetics are best not to eat more. Steamed acacia flowers are not easy to digest, the digestive system is not good people, especially the middle-aged and elderly people should not eat too much. At the same time, allergic people should also be careful to eat acacia flowers. Sophora is not only edible, but also a good medicine. It is usually harvested in the summer when the flowers are open or when the buds are formed, and is best when it is large, tight, yellow-green in color, and without stalks or leaves. Main components: raw acacia flowers contain mainly rutin (Rutin, Rutin) or its compounds, wax, green pigment, resin, condensed tannins, pigments, proteins (or mucus), amino acids (or peptides), sugar and vitamin A, etc., fried acacia flowers are basically the same as the raw acacia rice, only part of the amino acids (or peptides) or sugar has been destroyed, a slight increase in tanning substance content. Triterpenoid saponins from dried flower buds, hydrolyzed to Betulin (Betulin), Sophoradiol (Sophoradiol) and glucose, glucuronic acid (Glucuronic acid). From the flower buds are also obtained from the acacia rice methyl, ethyl and propyl, methyl is different from rutin flavonoids, ethyl and propyl are sterols. Rutin in Sophora japonica can be hydrolyzed to Quercitrin under the action of acid or enzyme. Pharmacological effects: 1. Effects on the cardiovascular system Sophora japonica has a mild excitatory effect on the isolated frog heart, and has a blocking effect on the cardiac conduction system. Rutoside, quercetin, quercetin can also increase the contraction and output of isolated and in situ frog heart, and can slow down the heart rate. Quercetin can dilate coronary blood vessels and improve myocardial circulation. Rutoside can make the lower limbs of the toad and rabbit ear vasoconstriction. Sophora liquid, Sophora tincture on anesthetized dogs and cats have temporary significant lowering of blood pressure. Rutoside and its preparations have antihypertensive effect, quercetin can also reduce blood pressure for a short time. 2. 2. Quercetin can effectively reduce the cholesterol content in liver, aorta and blood of experimental hypercholesterolemia rats and increase the stability of cholesterol-protein complexes when injected subcutaneously at 10mg. It has preventive and therapeutic effects on experimental atherosclerosis. 3. 3. Rutin and its glycoside quercetin can maintain the normal resistance of capillaries, reduce vascular permeability, and restore the normal elasticity of capillaries that bleed due to increased brittleness. Quercetin can enhance the resistance of skin capillaries of guinea pigs and rats, reduce vascular permeability, and its stability of capillaries is 1/3 stronger than that of rue glucoside. Continuous application of large quantities of rue glucoside and quercetin can prevent lung hemorrhage due to decompression of rats. 4. Anti-inflammatory effect Rutoside and quercetin can inhibit paw swelling caused by histamine, egg white, 5-hydroxytryptamine, formaldehyde, polyvinylpyrrolidone and hyaluronidase-induced foot and ankle swelling in rats. Rutoside can significantly inhibit traumatic edema in rats, and can prevent the occurrence of conjunctivitis, otitis, pulmonary edema. For rabbits due to mustard oil-induced conjunctival edema, only a slight inhibitory effect, such as rutoside dissolved in propylene glycol, to prevent the inflammation of the effect is better. Intravenous injection of rutoside inhibited the allergic inflammation of skin and joints caused by horse serum in rabbits. The sodium salt of rutoside sulfate can accelerate the recovery of hind limb thrombophlebitis caused by turpentine injection in dogs. 5, antispasmodic, anti-ulcer effects Quercetin can reduce intestinal, bronchial smooth muscle tone, its antispasmodic effect than rutin 5 times stronger. The antispasmodic effect of quercetin is 5 times stronger than that of brassinolide. Brassinolide can reduce the gastric motility of rats, and can relieve barium chloride-induced spasm of small intestinal smooth muscle. Subcutaneous injection of rutiloside 5 ~ 10mg / kg, can significantly reduce the number of foci of gastric ulcers induced by ligation of the pylorus in rats, the efficacy of reflex gastric ulcers than the effectiveness of kelin. Sophora japonica liquid (containing little rutinoside) injected into the intestinal lumen of rabbits, can stimulate the intestinal mucosa to increase exudate. 6. Antipathogenic microorganisms Sophora japonica flower infusion (2:5), in the test tube on Trichophyton corynebacterium, Xanthophyton xylostroboidum, Audu ounce of small buds jock itch, woolly small buds jock itch, asterisk nucifera and other skin pathogenic fungi have different degrees of inhibition. In vitro, Rutoside and Quercetin have antibacterial effect on some bacteria; they also have inhibitory effect on viruses. 7. Other effects Rutoside has a protective effect on X-ray irradiation. Sophora japonica contains hemagglutinin, which has the effect of agglutination on blood cells. Large doses of tincture of acacia can cause some central reflex inhibition. Generally speaking, it is believed that the rue glucoside cannot be absorbed orally, so it is not certain whether the oral use has a therapeutic effect. However, it has been reported that it can be absorbed after oral administration. Experiments showed that the charcoal decoction of Sophora japonica given to mice by gavage could significantly shorten the bleeding time and coagulation time. Its hemostatic and coagulant effects may be related to its tannin content or the presence of other hemostatic and coagulant components. The charcoal of Sophora japonica can shorten the time and reduce the bleeding volume of traumatic bleeding in rats; the solution of Sophora japonica with rutin removed has a significant hemostatic effect on traumatic bleeding in rats; rutin has a significant inhibitory effect on the pitting hemorrhage generated by negative pressure on the skin and the experimental pulmonary hemorrhage. Rutin has a preventive effect on experimental frostbite in rabbits by gavage. Compatibility: Sophora japonica with gardenia: Sophora japonica is bitter and cool in nature, it can cool blood and stop bleeding, it can clear intestinal heat and diarrhea the liver meridian; gardenia is bitter and cold in nature, it can clear the heat of qi and blood, it can relieve dampness and stop bleeding; fried charcoal is used in medicine, it can cool blood and stop bleeding in the midst of clearing the heat. Gardenia gardenia clears heat in lungs and Sophora japonica clears heat in intestines and internal organs together **** it is effective in clearing heat and dampness, cooling blood and stopping bleeding; if charcoal is used in medicine, it is more effective in stopping bleeding. It is used for the treatment of blood in stool, hemorrhoidal bleeding, bloody diarrhea, and leakage of blood when there is fire in the large intestine or damp-heat accumulation.
