Total Antioxidant Capacity of Thai Herbal Teas by the Ferric Reducing Antioxidant Power

Abstract:

Article Preview

The main objective aimed to compare in vitro antioxidant power of different recipes of Thai herbal teas including of Tatirot, Krajeab, Kamfoi, and Kesorn Bua. The ferric reducing/antioxidant power (FRAP) assay was used to measure the total antioxidant power of freshly brewed tea. Results showed that different Thai tea recipes had slightly different in vitro antioxidant power. The herbal teas recipe was expressed as µM of antioxidant power/g of dried Thai tea recipes. Values ranges as 555.62±0.77-908.43±0.69 µM/1g of Thai herbal tea, especially Krajeab tea showed strongly antioxidant of 908.43±0.69 µM/1g of tea when compared with other samples. Therefore, it has confirmed that the antioxidant power of Thai herbal tea recipes is considerably intermediate activity than vitamin C
