Extractions are used when we want to separate substances. One way this can be done is by using a solvent in which a desired substance dissolves in and the undesired substance does not dissolve in. Coffee flavor from coffee grounds is a great example, as we leave behind the coffee grounds and obtain a great flavored morning beverage.

A soxhlet extraction is glassware commonly used to extract compounds from plants to discover active compounds such as natural pharmaceuticals. Compounds extracted from plants or animal material are commonly called natural products. Some natural products are very useful chemical species for the production of drugs and ointments
