API Powder is fully defined in ICH Q7A as any substance or mixture of substances intended for use in the manufacture of pharmaceutical products and, when used in pharmaceutical products, as an active ingredient of pharmaceutical products. Such substances have pharmacological activities or other direct effects in the diagnosis, treatment, symptom relief, management or prevention of disease, or can affect the function or structure of the body. The active ingredient of a medicine. Only when an API is processed into a pharmaceutical preparation can it become a medicine for clinical application. alprazolam api powder,pregabalin api powder,buy api powder,api ingredients Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptidenootropic.com
According to its source, apis are divided into chemical synthetic drugs and natural chemical drugs.
Chemical synthetic drugs can be divided into inorganic synthetic drugs and organic synthetic drugs. Inorganic synthetic drugs are inorganic compounds (very few are elements), such as aluminum hydroxide and magnesium trisilicate for the treatment of gastric and duodenal ulcer, etc. Organic synthetic drugs are mainly made of basic organic chemical raw materials, through a series of organic chemical reactions and drugs (such as aspirin, chloramphenicol, caffeine, etc.).
Natural chemical drugs can also be divided into biochemical drugs and phytochemical drugs according to their sources. Antibiotics are generally produced by microbial fermentation and belong to the category of biochemistry. In recent years, a variety of semi-synthetic antibiotics are the combination of biosynthesis and chemical synthesis products. Among apis, organic synthetic drugs account for the largest proportion of variety, yield and output value, which is the main pillar of chemical pharmaceutical industry. The quality of the API determines the quality of the preparation, so its quality standards are very strict. All countries in the world have formulated strict national pharmacopoeia standards and quality control methods for the widely used APIS.
Specific API after processing -- pharmaceutical preparations
The term API is used mainly in relation to the finished product. Mainly raw materials obtained by chemical processing means, supply raw materials for the production of finished drugs. For example, cefpirome sulfate for injection is a drug, then cefpirome sulfate is an API
Raising chicken sheds and vegetables
After raising chickens in greenhouses, the presence of chicken worms and residual manure can significantly impact the growth of vegetables. To ensure successful vegetable cultivation in such environments, it's essential to follow a few key steps carefully.
First, after the chickens have been slaughtered, the greenhouse should remain unused for a period of time. During this period, deep plowing should be done to a depth of 40 cm. This helps break up compacted soil and improve aeration. After plowing, water should be applied thoroughly to dilute any remaining fertilizer or manure solution in the soil. Once the water is absorbed, the vents should be closed, and the greenhouse should be left sealed to create a hot, humid environment. This process helps accelerate the decomposition of chicken manure, reducing the risk of chemical burn to young plants.
Secondly, in greenhouses where chickens have been raised, the high concentration of organic matter can lead to excessive ammonia production. If not properly managed, this ammonia can accumulate and cause serious damage to vegetable seedlings, resulting in "smoke injury" or even plant death. Therefore, before planting vegetables, it's crucial to ventilate the greenhouse adequately and allow time for ammonia to dissipate. Monitoring the air quality inside the greenhouse is also recommended to ensure a safe environment for the crops.
Lastly, the risk of fruit fly infestation should not be overlooked. Large chicken sheds often become breeding grounds for various species of fruit flies if not properly managed. These pests can quickly spread and damage young vegetable plants. To prevent this, it's important to treat the planting holes with an appropriate insecticide. A commonly used option is 50% phoxim emulsifiable concentrate, which can both prevent and control fruit fly infestations effectively. Regular monitoring and timely application are essential to maintain a healthy growing environment.
By following these practices, farmers can significantly reduce the risks associated with growing vegetables in previously used chicken greenhouses, ensuring better yields and healthier crops.
