During winter, potted aloe vera requires careful temperature management. The plant is sensitive to cold, and lower temperatures can cause significant damage. To protect it from freezing, special care must be taken throughout the season. 1. Insulation: Aloe vera becomes dormant when the temperature drops below 5°C. If indoor heating is available, move the pot inside for protection. However, if the temperature cannot be maintained above 5°C, additional insulation measures are necessary. You can dig a rectangular hole in the ground, place the potted aloe inside, cover it with a bamboo frame, and seal it with two layers of plastic film. In extremely cold weather, add a blanket or straw covering at night, and remove the plastic during midday to allow ventilation and air exchange. 2. Watering: Aloe vera prefers dry conditions. Water the plant every 15 to 20 days during winter, and reduce or even stop watering in colder periods. If the indoor air is dry, mist the leaves occasionally to maintain humidity without overwatering. 3. Fertilizing: In addition to using organic fertilizer, it's important to apply nutrients regularly. During winter, fertilize once every 40 to 50 days. Use a urea solution with a concentration not exceeding 2%, or apply foliar fertilizer at a concentration of no more than 0.1%. Be careful not to over-fertilize, as this can harm the plant. 4. Light: Ensure the aloe receives plenty of sunlight during winter. Place it in a sunny spot, such as a south-facing window or a sheltered area. Move it outside after 9 a.m. and bring it back indoors before 3 p.m. Another effective method is to use a transparent plastic bag around the pot. Attach a wire frame to the edge of the pot, then wrap the plant and pot with a plastic bag. This helps increase both temperature and humidity without blocking sunlight. However, remove the bag promptly when the room warms up to avoid overheating or poor air circulation. Leaving the bag on for too long can lead to high internal temperatures and lack of airflow, which may harm the plant. By following these steps, you can ensure your potted aloe vera survives the winter safely and remains healthy for the next growing season.
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.
