Extraction methods are techniques used to separate a desired substance from a mixture or compound. Commonly used in various fields, such as chemistry and food processing, these methods can include techniques like distillation, filtration, and solvent extraction. Each method has its own specific applications and is chosen based on the properties of the substances involved. In the context of natural products, extraction methods are essential for obtaining compounds from sources like plants or minerals. For example, essential oils are often extracted using steam distillation, while caffeine can be extracted from coffee beans using solvent extraction. These methods help in isolating valuable components for further use or study.
