Novel Approaches in Green Extraction for Natural Medicines

Green extraction is based on discovery and design of extraction process which will reduce unit operation, reduce energy consumption, reduce time consumption, reduce organic solvent use, alternate solvent with water or agro-solvent and ensure safe and high-quality extract. In this study the conventional extraction methods and various green extraction methods were compared. Both these studies on extraction process were done in the past, in this review those studies were compared. From this we can know that which method is suitable for extraction which will not harmful for the environment, promote the health of patient, produce by-product or co-product instead of waste.
