I. Overview The dry rhizome of the white plant of the white plant Amaranthus. Alias: even grass, Gan root, white to, Zhu Lan, violet. It is a commonly used traditional Chinese medicine that has functions such as invigorating the lungs, stopping bleeding, and reducing swelling and myogenic growth. Indications tuberculosis hemoptysis, bronchiectasis hemoptysis, gastric ulcer vomiting blood, hematuria, bloody stools embolism; external treatment bleeding trauma, burns, hand, foot and palpebral fissure embolism. White peony hemostasis is particularly effective, and now with the plastic plaque made of white peony, used for liver and spleen surgery attached to the knife, instead of blood forceps, the effect is particularly good. With a fast clotting effect, it can be used in surgery on behalf of the plasma. Mainly produced in Sichuan, Yunnan, Shaanxi, Gansu and other provinces throughout the country have cultivated. Second, the morphological characteristics Herbs perennial. Plant height 30 to 60 cm. Tubers succulent, white, with 2 to 3 forks and water chestnuts, fibrous roots, constant connate, racemes terminal, often flowers 3 to 8; flowers pale purple, petals are not neat. The capsule is cylindrical, with 6 longitudinal edges and slightly pointed ends. Seeds are small, mostly. Flowering from April to May and fruiting from July to August. There are two kinds of white pelicans. There is also a kind of yellow-white flower, leaf-shaped lanceolate, and white-leaved pelicans. Among the purple crocuses, there are large species and minor species, among which large tuber yields are higher. Third, the growth characteristics Hi warm, cool and damp environment; not cold. Fertile, loose and well-drained sandy soil or humus loam soil is required. Requires cultivation on shady slopes or relatively damp land plots. Fourth, cultivation technology 1. Select land preparation; choose loose sandy fertile soil and humus soil, warm, slightly damp environment, not cold. When planting in well-drained mountainous areas, it is better to choose the shade-land planting. Plow up more than 20 centimeters of soil, apply manure and compost, apply 1,000 kilograms of manure per acre. There is no farmyard manure to spread 50 kilograms of compound fertilizer. Turn the soil and fertilizer evenly. Shallow plough once before planting, and make the soil fine and smooth, and make it 130-150 cm wide. 2. Propagation method; white pods are harder to sow with seeds, and tubers are easier to reproduce. At the beginning of September-November, the white plover was excavated. Medium size, many shoots, and disease-free tubers were selected. Each one had 1–2 buds, which were sown after planting with wood ash. Open ditch 20---25 cm, depth 5-6 cm, place one tuber by 10-12 cm of plant spacing, shoot upwards, fill in, compaction, water, cover grass, keep moist, 3 - Seed emergence in April. Mu seedlings 100 kg, 3. Field management (1) Weeding and weeding In the field, weed management requirements are very strict. We planted and sprayed acetochlor to seal off the shoots. During the 5--June period, the white storks grew vigorously and the weeds grew quickly. Weeding was performed. Weeding combined with glutinous rice cake, weeding when weeding, so as not to hurt the roots. (2) Dressing up the white peony is a favorite fertilizer plant. Once a month, potassium dihydrogen phosphate or thin human urine and feces urine is sprayed. In July and August, it stops growing and enters dormancy, but it is necessary to prevent overgrown weeds. (3) Irrigation and Drainage White pods are pleasing to the shade, they are often kept moist, and they are watered during droughts. They are watered every morning and evening from July to September. The white pelican is afraid of plutonium, and heavy rain is drained in time to avoid injury. 4. Pest Control 1 The rot disease in the south occurs mostly in the spring and summer rainy season. Control methods: Pay attention to drainage, waterproof, deep digging drainage ditch. 2 Ground tigers and golden needleworms can be manually killed and killed or mixed with poisonous soil. The bed was flooded with a 50% solution of 500% zincphospate EC. V. Harvesting and Processing After the planting of white hoe for 2 to 3 years, when the above-ground stems are withered during September-October, the excavated tubers are removed from the soil for processing. The tubers were individually removed and the tubers of the new stalks were left for seeding. The stems were cut off and soaked in clean water for 1 hour. The soil was washed and put in boiling water for 5 to 10 minutes. Remove the rough skin and fibrous roots and sieve to remove impurities. General harvesting 800-1000 kilograms of harvested products, can be processed 200--300 kilograms. Take a large, full, white, translucent, solid quality is better. Six, the active ingredient tuber contains starch, glucose, volatile oil; root contains white mannan. 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.peptide-nootropics.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
