COMPARATIVE STUDY OF ANTIOXIDANT AND FREE RADICAL SCAVENGING ACTIVITY OF FAMOUS GREEN TEA BRANDS IN INDIA
AbstractGreen tea, one of the most popular beverages in India and around the world, is made from dried leaves of the Camellia sinensis L. tea plant. The same flavour, such as lemon and honey from each brand, has been employed to prevent errors in chemical composition caused by variations in available flavours. Samples were prepared for infusion by heating distilled water to 100℃ for ten minutes. The amount of tannin, flavonoid, and phenolic compounds in total antioxidants was calculated. Tanza (TZ) had the highest concentrations of flavonoids and phenolics, measuring at 8.560667±0.093383 RE/ml and 45.4233±0.274 GAE/ml of sample, respectively. Tetley (TL) had the highest tannin content, 39.194 ± 0.178037 TAE/ml of sample. The DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) assay was used to measure the free radical scavenging activity of the samples. Vahdam green tea showed the highest activity, with 80.74333 ± 0.298124%; this may be because to its organic cultivation. Green tea can be consumed as a supplement to enhance general health as it is a great source of free radicals.
