Tea in general and Green tea in particular, are gaining increasing consumer attention due to a growing awareness of health benefits derived from their use, but research in product development of flavored Green tea is limited. The objectives of the study were to conduct Nutritional analysis, phytochemical analysis, antioxidant and antibacterial activity of Withania somnifera stems, Cinnamonbark, Tinospora cordifolia stems, Terminalia arjuna bark, Green teaand formulation mixture of these herbs in order to assess their potential for new herbal tea development. These herbs are a rich source of natural antioxidants and polyphenols. Total phenolics and flavonoids contents were obtained for methanolic extracts for each herb sample. Antioxidant activities of the extracts were estimated using DPPH radical scavenging activity and FRAP assay. Formulation mixture is an excellent sources of calcium, magnesium and phosphorus. The methanolic extracts showed good antibacterial activity in Bacillus subtilis, Bacillus cereus and E.coli. GC/MS screening showed the presence of several useful compounds indicating that the samples hold the potential to be stated under â€œNutraceuticalsâ€. HPLC method was developed for the estimation of quercetin, kaempferol, rutin & epicatechin in the formulation mixture extract. Formulation of green tea with these herbs was done, which imparts colour, aroma, flavor, astringency and overall acceptability to Green tea and impart many health benefits.
