Tea (Camellia sinensis) is one of the most widely consumed beverages in the world. Tea extracts are source of polyphenols, which are antioxidant components. Green tea phenolic compounds are predominately composed of catechin derivatives, although other compounds such as flavonols and phenolic acids are also present in lower proportion. The main catechin compounds found in green tea are (-) Epigallocatechin Gallate (EGCG), (-) Epigallocatechin (EGC), (-) Epicatechin Gallate (ECG) and (-) Epicatechin (EC) and other compounds. An antioxidant is a molecule capable of inhibiting the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons from the substance to an oxidizing agent. Oxidation reactions can produce free radicals. A molecule with one or more unpaired electron in its outer shell is called a free radical. Free radicals are formed from molecules via breakage of a chemical bond such that each fragment keeps one electron, by cleavage of a radical to give another radical and, also via redox reactions. In turn, these radicals can start chain reactions that...

Alterative medication and natural remedies have been used from ancient time for the treatment and wellbeing of human. Medicinal plants are considered to be effective and for most important for the human health.

The pulp can be used as flavouring in ice cream. Between 50-80% of the fruit is edible. The Vitamin C content is appreciable (35-42 mg/100 g) and slightly higher than in grapefruit. The nutrient value of thiamine, potassium and dietary fiber is also significant. It is reported to contain various chemical compounds such as alkaloid, isomeric hydroxyl ketones from leaf, acetogenin, samaquasine, annonacin and annonastatin from seeds, acetogenin, squamone from bark of it. Various studies have been reported as an antibacterial, antidiabetic, antitumor,...
