Green extraction: Concepts, principles, solutions, future prospect and challenges

Since the early days, natural products have played a significant role in drug discovery and development. However, the extraction process of these compounds often includes many complex steps, consumes a lot of energy and a large volume of solvents, which can have a significant impact on the environment as well as human health. Therefore, it is necessary to find better ways to improve the yield of extraction, while minimizing risks that may affect the environment and humans.
