Sustainable extraction bioactive compounds procedures in medicinal plants based on the principles of green analytical chemistry: A review

Abstract

This review article points out, through an overview, aspects that are related to the procedures established by green analytical chemistry, for the extraction of bioactive compounds in plants, through the use of assisted techniques, as well as green solvents. Procedures that have less negative impact on the environment are being increasingly required for the extraction of biocompounds in the area of ​​analytical chemistry due to aspects of sustainability, profitability and efficiency. To this end, green procedures aim to design environmentally benign chemical processes and synthetic methodologies, to eliminate or reduce the use of dangerous and toxic chemicals at any stage of production in industry or even in the laboratory. These extraction procedures will be defined as “green”, when using alternative solvents, reducing energy consumption, in addition to ensuring the safety and high quality of the extract. This review provides an overview of the green procedures applied and which had an effective action in the extraction of bioactive compounds in medicinal plants, supported thus by innovative, sustainable, and unconventional energy sources.
