Abstract

Bioactive compounds are chemical substances that have biological effects favourable to human health. Many foods contain bioactive compounds, such as fruits, vegetables, grains, and nuts, but animals only have extremely small levels of these substances. Many industries use bioactive compounds extensively, including poultry, agriculture, cosmetics, biofuel, and medical research. Techniques for extraction are necessary to get potential bioactive compounds. The ultrasound-assisted extraction (UAE) is identified as one of the most efficient methods, given its benefits for the extraction of bioactive substances. This review paper focused on the fundamental concepts behind the ultrasonication process as well as a recently published study on the use of ultrasound-assisted extraction (UAE) to extract bioactive compounds from a wide range of sources for various applications.
