Tea is one of functional drink offer numerous benefits such as the maintenance of good health due to its antioxidant property. Thus, instant tea powder from flower is an interesting alternative product for consumers. This work aims to develop 9 formulation of instant flower tea powder from Curcuma sessilis Gage., Clitoria ternatea Linn. and Bombax anceps Pierre. Also the total phenolic content and the antioxidant activities were investigated by using DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity assay. The results demonstrated that each formulation showed statistically significant in total phenolic content and antioxidant activity (p<0.05). The formulation No. 3 (Curcuma sessilis Gage at ratio between herbal solution and sugar of 2:1 by weight) exhibited the highest total phenolic content of 457.35 ± 0.02 mg GAE/g. Moreover, formulation No. 3 (Curcuma sessilis Gage. at ratio between herbal solution and sugar of 2:1 by weight) exhibited the greatest percent of DPPH radical scavenging activity of 96.69 ± 0.00 % and IC₅₀ of 0.06 ± 0.00 g/ml. Conclusively, Curcuma sessilis Gage. shows effectively antioxidant property which is suitable to develop as instant flower tea powder product for health care and reducing the risk of diseases such as cancer, heart diseases and cardiovascular diseases.
