These plant monomers are usually secondary metabolites of plants, such as flavonoids (flavonoids), alkaloids (alkaloids), terpenoids (terpenoids), phenolics (phenolics), etc., which play a variety of physiological functions in plants such as defense, signal transduction, and antioxidant. Due to their pharmacological activity, high-purity plant monomers are often used in pharmaceuticals, health products, cosmetics and other biotechnology products.
For example, Naringenin is a high-purity plant monomer extracted from citrus plants with antioxidant and anti-inflammatory activities; Corosolic acid is a high-purity active monomer extracted from loquat leaves, which is considered to be effective in treating type 2 diabetes and obesity.
Extraction and preparation of high-purity plant monomers usually require a complex separation and purification process, including extraction, column chromatography, crystallization, recrystallization and other steps to ensure the purity and activity of the final product. These processes may be required by specialized biotechnology companies.

what is API?
High-purity plant monomer refers to one or more single chemical components with specific biological activity or pharmacological effects extracted from plants, and its purity is usually high, meaning that the content of the component in the extract reaches a certain percentage, and the content of other impurities or irrelevant components is low.
Seedless Shatang Tang Cultivation Technology
Non-nuclear Shatang Tang is a unique citrus variety known for its crown-shaped, round head and dense branching. It exhibits moderate vigor, strong fruiting ability, and starts bearing fruit within 2 to 3 years after planting. The annual yield per mu ranges from 2000 to 3000 kg, with yields exceeding 5000 kg after four years. Its ripening period lasts throughout the year, from January to December. The fruit is round or oblate, with a cinnabar-like red color, compact skin and flesh that are easy to separate, and a juicy, sweet taste without any nuclear residue. It has a crisp texture and high quality.
This variety is highly adaptable, cold-resistant, and has a long growth period, short dwarfing characteristics, early maturity, high yield, and stable production. Due to these advantages, it has become a popular choice in the citrus market. Non-nuclear Shatang oranges are suitable for cultivation in both mountainous areas and paddy fields, making them a versatile option for farmers.
To ensure high-quality production, proper planting techniques are essential. The orchard should be planned with drainage and irrigation systems, as well as roads for easy management. In paddy fields, shallow and deep ditches can be used to manage water levels, while in dry land, soil retention is key. Planting should avoid winter months when strong new shoots may develop, leading to excessive spring growth. When planting, roots should be dipped in a mixture of yellow mud, manure, and specific fertilizers to promote root development. Care must be taken not to over-fertilize, as this can lead to root rot or seedling death.
Soil management is crucial for the healthy growth of non-nuclear Shatang oranges. Regular tilling and organic matter addition improve soil structure and support root development. Intercropping with grasses like Chinese wolfberry helps maintain soil fertility and provides natural pest control. Water management varies by season, with careful attention to moisture levels during summer and autumn to prevent waterlogging, while winter requires controlled watering to encourage flower bud differentiation.
Fertilization should be balanced, combining organic and chemical sources. Nitrogen, phosphorus, potassium, and trace elements are all important for different growth stages. Proper timing and application methods are necessary to avoid over-fertilization and ensure optimal tree health. Pruning plays a vital role in shaping the tree, promoting fruiting, and maintaining productivity. Timely pruning helps manage tree vigor and encourages even distribution of branches.
Pest and disease control is critical for successful cultivation. Common pests include leaf miners, aphids, and scale insects, while diseases such as citrus canker and anthracnose can significantly impact yield. Integrated pest management strategies, including biological controls and selective pesticide use, are recommended to minimize chemical exposure. Spraying should be done under favorable weather conditions to maximize effectiveness and reduce environmental impact.
Flower and fruit promotion techniques, such as controlling fertilizer and water, using growth regulators like gibberellin (920), and implementing ring cutting, help increase fruit set and yield. These practices, combined with regular monitoring and timely intervention, ensure a bountiful harvest.
Harvesting should be done in stages to maintain tree health and fruit quality. Over-harvesting at once can stress the tree, leading to reduced productivity in subsequent seasons. By following these comprehensive cultivation techniques, growers can achieve high-quality, sustainable production of non-nuclear Shatang oranges.
