Wuling Powder, Four Gentlemen's Decoction, and Shenling Baizhu Powder are all famous prescriptions of traditional Chinese medicine, each of which has its own main uses.
Wuling Powder has the effect of promoting water seepage and warmed yang and qi. It treats internal symptoms of water and dampness, such as unfavorable urination, headache and slight heat, irritation and thirst, and even vomiting when water enters; or palpitations under the umbilical cord, saliva and dizziness; or short breath and cough; or edema, diarrhea, etc., all have good effects. This is by regulating the metabolism of human water, so that the evil of water and dampness can be discharged, and the normal transmission and metabolism of human body fluid can be restored.
Four Gentlemen's Decoction is a basic prescription for nourishing qi and strengthening the spleen. Indicates the spleen and stomach qi deficiency syndrome, face color withered white, low voice, shortness of breath, lack of food and loose stools, pale tongue coating, weak veins, etc. The four herbs of ginseng, Baizhu, Poria cocos, and licorice are used to replenish middle qi, strengthen the spleen and stomach, restore the functions of spleen and stomach transportation and transformation to normal, and have active qi and blood biochemistry, thereby improving all symptoms caused by weakness of the spleen and stomach.
Shenling Baizhu Powder is used to nourish qi and strengthen the spleen, moisturize and relieve diarrhea. It is often used in the spleen deficiency and dampness syndrome. The symptoms are that the diet does not melt, the chest and epigastric are stuffy, the intestines and diarrhea, the limbs are weak, the body is thin, the complexion is yellow, the tongue is On the basis of invigorating qi and strengthening the spleen, the prescription is more heavily moisturized and anti-diarrhea, and has a significant effect on diarrhea such as spleen and stomach weakness and dampness.
Although all three are related to the spleen and stomach, Wuling Powder focuses on treating water and dampness and stopping inside, Sizheng Decoction focuses on invigorating qi and strengthening the spleen, and Shenling Baizhu Powder focuses on removing dampness and anti-diarrhea on the basis of strengthening the spleen, each with its own emphasis. Clinical application needs to be selected accurately according to the specific syndromes.

To prepare pentenyl 4-cyanonicotinamide, there are various methods.
First, it starts with common organic compounds and is prepared by multi-step reaction. First, take a suitable alkenyl-containing raw material, and under specific reaction conditions, use a catalyst to assist it to combine with a cyanide-containing reagent. This step requires precise temperature control, time control and control of the ratio of the reaction material, and proper combination of pyrene and cyano groups to obtain an intermediate containing alkenyl and cyano groups.
Then, this intermediate is reacted with a compound containing a pyridine ring. The structure of the pyridine ring is special. When reacting with intermediates, special solvents and reaction aids may be selected to rearrange and combine the chemical bonds between the two, and gradually form the basic structure of pentaenik 4-cyanonicotinamide. Finally, after purification and refining, impurities are removed to obtain a pure product.
Second, inspiration can be found from natural products. There are plants or microorganisms in the world, and their metabolites may have similar structures. By means of biotechnology, such as fermentation engineering, genetic engineering, etc., the metabolic pathways of related organisms can be regulated. Or introduce specific genes to change their biosynthetic mechanisms, so that organisms can produce pentaenik 4-cyanonicotinamide in the process of growth and metabolism. Although this biosynthesis method has the potential for green and high efficiency, it requires high requirements for biotechnology, and it is necessary to study biological characteristics and gene regulation methods.
Third, bionic synthesis strategies can also be used. Simulate the process of biosynthesis of such compounds in nature and imitate it by chemical means. Insight into the mechanism of enzyme catalysis in organisms, design enzyme-like catalysts, and catalyze the gradual conversion of substrates under mild conditions in vitro. This bionic method can reduce reaction steps, reduce energy consumption, and is more in line with environmental protection concepts, but it poses a great challenge to the design of chemical synthesis and the development of catalysts.

Pentahydroxytryptophan 4-guanidine aldehyde is a strange substance with many specific physical properties.
Its appearance, at room temperature, is often in the state of fine powder, white and pure, like the first snow in winter, delicate and uniform. Viewed under the light, there is a faint gleam, which seems to contain endless mysteries.
When it comes to solubility, this substance has a unique solubility in water. In moderate water temperature, some of it can be slowly dissolved, making the water slightly cloudy, but not completely dissolved, as if maintaining a delicate balance with water. In organic solvents, such as ethanol and ether, its dissolution performance is also different. In ethanol, the dissolution rate is slightly faster, and a uniform mixture can be formed, just like water emulsion blending; in ether, it shows a different state, or layered, or suspended, showing complex interactions.
Melting point is also one of its remarkable properties. After careful trial, when the temperature rises to a specific degree, about [X] degrees Celsius, this substance will gradually soften and melt like ice and snow in the warm sun, gradually changing from solid to liquid. This process is smooth and orderly, showing the transformation of its molecular structure under the action of heat.
Furthermore, its stability is also worth exploring. In ordinary environments, without the interference of special factors, it can maintain a relatively stable state, and the molecular structure is not easily changed. However, if it is in high temperature, high humidity, or encounters specific chemical substances, it is like a calm lake thrown into a boulder, the stability is broken, or a chemical reaction occurs, or decomposes and deteriorates, showing different chemical forms and properties.
Pentahydroxytryptamine 4-guanidine tryptophan aldehyde has potential uses in many fields due to its unique physical properties, waiting for those who are interested to explore and explore in depth.

In the process of storage and recovery, pay attention to the following things:
First, the degree of resistance is very important. These two should be stored in a low-temperature place to avoid high-temperature baking. If the degree of resistance is high, it may cause the production of the amide and amide, such as the modification of the temperature, the activity is reduced, and the heavy case may lose its inherent effect. For example, in summer, if there is no reduction strategy, the temperature of the amide may be damaged.
Second, the degree of resistance should not be ignored. The tidal environment is easy to make the amide absorb moisture. Once the moisture is absorbed, it may cause its physical shape to be changed, such as the temperature, etc., and it may be reversed. Therefore, when it is stored, the tools also have the ability to prevent moisture, such as sealing, etc.
Third, anti-corrosion measures are indispensable. Fifth, common amides may be dangerous to a certain extent, such as corrosion, irritation, etc. The operator should take measures to prevent damage, such as anti-wear, gloves, masks, etc. The container and storage containers are also corrosion-resistant and well sealed to prevent leakage. Fourth, it is necessary to store insulation. Do not mix oxidation, acid and other substances. Due to the chemical reactions of five, common amides or common amines, safety accidents are caused. It is necessary to separate incompatible materials to ensure the safety of storage.

The five-ocean fish carp and the four-season osmanthus are all common in the pharmaceutical market, but their prices vary from time to time. In today's world, the price of the five-ocean fish carp ranges from five to fifty dollars per catty of twenty. The change in price is related to the season. In spring and autumn, the catch is quite abundant, but the price is slightly cheaper; in summer and winter, the fishing is difficult, and the price rises.
As for the four-season osmanthus, the price is about eighty to one hundred and fifty dollars per two. Its production is also subject to climate, water and soil. If the weather is good and the mountains are fertile, the goods are sufficient and the price is flat; in the year of different disasters, the output is sparse, and the price is high.
The city people trade, and the voice of bargaining is endless. Merchants who seek profit must also take advantage of the current situation and observe supply and demand. To the extent that there is a mixture of authenticity in the market, purchasers should be careful not to be deceived by inferior goods, so as to obtain affordable prices and superior products.
