Introduction to Calendula officinalis

Calendula officinalis, commonly known as calendula, is a plant with a long history of use in various fields. It is a bright - colored flower that has been cherished for centuries. Native to southern Europe, calendula has now spread across the world, and its popularity continues to grow due to its remarkable properties.

Calendula is an annual or biennial plant. It has a daisy - like appearance with its yellow or orange petals. The plant can reach a height of about 30 - 60 centimeters. It is relatively easy to grow, which makes it accessible for both commercial and home cultivation.

Organic Cultivation of Calendula officinalis

Soil Requirements: For organic calendula cultivation, the soil quality is crucial. Calendula prefers well - drained soil that is rich in organic matter. A soil pH between 6.0 and 7.5 is considered ideal. Organic fertilizers such as compost and manure can be added to improve the soil fertility and structure.

Seeding and Planting: Calendula seeds are usually sown directly into the soil in spring or fall. The seeds should be sown at a depth of about 1 - 2 centimeters. Adequate spacing between plants is necessary to ensure proper growth and air circulation. A spacing of about 20 - 30 centimeters between plants is recommended.

Watering and Maintenance: Calendula requires regular watering, especially during dry periods. However, over - watering should be avoided as it can lead to root rot. Organic mulch can be used around the plants to retain moisture and suppress weeds. Pest control in organic calendula cultivation mainly relies on natural methods such as introducing beneficial insects and using plant - based repellents.

Extraction Methods of Calendula Extracts

Solvent Extraction: One of the common methods for extracting Calendula Extracts is solvent extraction. Organic solvents such as ethanol or hexane can be used. In this process, the calendula plant material is soaked in the solvent for a certain period. The solvent then dissolves the active compounds in the plant, and after filtration and evaporation of the solvent, the Calendula Extract is obtained. However, it is important to ensure that the solvents used are of high quality and meet safety standards.

Supercritical Fluid Extraction: This is a more advanced extraction method. Supercritical carbon dioxide is used as the extraction fluid. It has the advantages of being non - toxic, non - flammable, and leaving no residue. The supercritical carbon dioxide can effectively extract the active ingredients from calendula while maintaining their integrity. This method is often used for high - quality Calendula Extract production due to its high efficiency and purity.
