"GREEN" DIRECTIONS MICROWAVE EXTRACTION IN CHEMISTRY OF NATURAL COMPOUNDS

Report 1. Methods for assessing the environmental performance of analytical procedures

Abstract

Over the past decades, areas related to the improvement of complex processing of vegetable raw materials and the creation of highly efficient methods for the isolation of biologically active substances (BAS), one of the approaches of which is microwave extraction (microwave-assisted extraction (MAE)), have received intensive development. At present, microwave extraction is one of the areas of analytical "green" chemistry, which quickly gained the position of one of the most effective methods for isolating compounds. The tendency of its development is the development and introduction of innovative approaches to reduce or eliminate the use of hazardous and toxic chemicals that comply with the principles of "green chemistry". To properly measure the effects of chemical processes on the environment, their special assessment is necessary. The review examines a variety of methods used to assess environmental friendliness, developed metrics of green analytical chemistry, including the NEMI labeling and EcoScale analytical. The question of assessing the environmental performance of analytical procedures for the microwave extraction of natural compounds is considered.
