Extraction of wide array of bioactives from complex plant materials is a challenging task. A number of conventional methods such as maceration, decoction, infusion, percolation, hydro-distillation and Soxhlettechniques are in use for extraction of various plantbioactives/functional components (FC). Nevertheless, there are serious concerns about the process safety, tediousness and environmentally hazardous nature of such techniques. Especially, the quality of end-use products /extracts thus is also questioable as far as food and therapeutic applications are concerned. In the era of optimal nutrition, there is increasing demand from food and nutra-pharmaceutical sector for the non-denatured and safer extracts. Hence, there is increasing interest of researchers and food scientistsin the developlment of alternative green extraction yielding food and nutra-pharmacetical grade extracts. The present lecture is designed with the main objective to highlight the principles of emerging green extraction whichare applicable for the effcetive recovery of high-value FC from diffferent plant materials. Findings of some of our own methodological developments related to green extraction such as enzyme-assisted extraction, ultrasound-assisted-extraction and supercritical fluid extraction (SFE) are also presented. Especially, improvement in extraction yield and nutraceutical quality of vegetable oils and natural antioxidant phenolics is focussed.
