Abstract
In recent years, pursuit for novel techniques for the extraction of bioactive compounds from natural sources has gained the attention of many researchers. Various conventional solid-liquid and liquid-liquid extraction methods and non-conventional technologies such as microwave and ultrasound assisted extraction, supercritical fluid extraction, pulse-electric field assisted extraction, enzyme assisted extraction etc. has been explored well in this area. This review aims at providing an extensive overview of general aspects of various natural bioactive compounds and different techniques and mechanism for the extraction of these compounds. Scope of the proposed topic: It is vital for the pharmaceuticals, food, cosmetic and chemical industries to be aware with latest technology choices and researches aimed at enhancing the yield and quality of bioactive compounds. The paper aims to discuss various techniques employed for concentration and purification of bioactive compounds and highlights the changes in extraction conditions to enhance the yield and quality of bioactive compounds so as to exploit them for human good.
Keywords: Extraction, bioactive compound, downstream processing.
