Abstract
Till date, various extraction and purification processes have been deployed to obtain liquid extraction of bioactive constituents from plants and their by-products. Traditional techniques such as maceration, hydro-distillation, soxhlet extraction, and hot water extraction have been deployed to extract valuable bioactive compounds from plant sources. These techniques suffer with the basic limitations of long extraction time, use of expensive and toxic solvents and degradation of heat sensitive compounds. On the other hand, the application of ultrasound assisted extraction (UAE) has been mostly explored in food and pharmaceutical processing schemes for the needful extraction of bioactive components. This is due to its simplicity, lower cost, lower processing time, lower solvent requirements, effective extraction efficiency, lower energy, higher reproducibility, scalability, and environmentally friendly nature.
