Active Pharmaceutical Ingredients refer to the raw materials used in the production of various preparations. They are the effective ingredients in the preparations. They are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction or biotechnology, but Substances that the patient cannot take directly.
According to its source,Active Pharmaceutical Ingredients are divided into two categories: synthetic chemical 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 (extremely elements), such as aluminum hydroxide and magnesium trisilicate used to treat gastric and duodenal ulcers; organic synthetic drugs are mainly composed of basic organic chemical raw materials, through a series of organic Drugs made by chemical reactions (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 made by microbial fermentation, which belongs to the category of biochemistry.In recent years, many semisynthetic antibiotics are the combination of biosynthesis and chemosynthesis.Among APIs, organic synthetic drugs account for the largest proportion in variety, yield and output value, which is the main pillar of chemical pharmaceutical industry.The quality of API determines the quality of preparation, so its quality standards are very strict. All countries in the world have formulated strict national pharmacopoeia standards and quality control methods for its widely used API

Feed turtle fresh feed to disinfect
During the turtle feeding process, everyone pays more attention to the disinfection of turtle ponds and water bodies, but often ignores the disinfection of feeds. Turtle artificial compound feeds that are self-manufactured or purchased are processed and manufactured without disinfecting. However, fresh feed (such as fish, insects, cockroaches, chironomid larvae, snails, cockroaches, fly maggots, and green leafy vegetables, etc.) should be rinsed with water first, soaked in 5% saline for 5 minutes, and then rinsed with clean water. After the feeding; green leafy vegetables should be soaked in clean water for 30 minutes, soaked pesticides, chopped or processed into a dish with a meat grinder, mixed with artificial compound feed. Turtle farmers should pay special attention to the disinfection of live feeds to prevent the occurrence of turtle diseases and poisoning accidents. (Senior veterinarian: Zheng Yanping)
