Abstract

Green tea is considered as the most popular beverage in the world due to their higher antioxidant’s contents, good taste, aroma, and lately reported health benefits. Green tea bioactive compounds have many beneficial health effects against cancer, cardiovascular disorders, obesity, diabetics and inflammatory disorders etc. Thus, these health functionalities of green tea extract mainly depend on the number of bioactive metabolites are extracted during green tea infusions preparation. Several factors can influence the extraction yields of green tea derived bioactive metabolites including extraction temperature, time, solvents, and solvent to solid ratio etc. However, this review will focus on the extraction efficiencies of green tea metabolites and their effect on type 2 diabetes with possible mechanistic exploration.
