Abstract

Herbal teas was are widely consumed by people around the world have high antioxidant activities. The flavor and color combination of specific teas enriches the aroma and appearance of the tea, producing a tea with fresh color and tastier flavor. This study determines the antioxidant activity of telang flower tea (Clitoria ternatea), pineapple tea (Ananas comosus), and the formula of the combination of telang flower tea and pineapple tea called TeNan. The antioxidant activities of herbal teas were measured by 2,2 Diphenyl-1-picrylhydrazyl (DPPH), Hydrogen Peroxide (H2O2), 2,2′-Azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), Ferric Reducing Antioxidant Power (FRAP) assay. The total phenol measurement used Gallic Acid Equivalent (GAE), while the flavonoid content measurement used Quercetin Equivalent (QE). The DPPH scavenging activities of telang flower tea, pineapple tea, and TeNan tea (IC50: 17.07%, 11.81%, and 22.22%), H2O2 scavenging activities (IC50: 26.62%, 41.81%, and 96.22%), ABTS-reducing activities (IC50: 2.51%, 3.39%, and 1.02%), and FRAP activities (IC50: 5.56%, 18.67%, and 7.48%). The total phenolic and flavonoid contents of TeNan tea were lower (9.44 μg GAE/100%; 3.46 μg QAE/100% sample concentration) than those of telang flower tea (16.20 μg GAE/100%; 4.88 μg QAE/100% sample concentration) but higher than those of pineapple tea (0.82 μg GAE/100%; 0.17 μg QAE/100% sample concentration). TeNan tea has the higher in ABTS and FRAP activities but lower in H2O2 and DPPH scavenging activities compared to telang flower tea and pineapple tea. In summary, telang tea has stronger antioxidant activity compared to pineapple and TeNan tea in FRAP and H2O2 assays.

Abstract

Herbal tea are popular because of their potential herbal medicine, a blend of herbal ingredients, promised to provide a specific purpose. The main purpose is to determine antioxidant activity in herbal teas (pandan mixed ginger) and in their infusions, as well as to obtain more complex information about the tea products. In this study, DPPH radical scavenging, H2O2 scavenging, ABTS reduction, and FRAP reduction assay were carried out. These assays are proved that the IC50 values of ginger are higher than PanJe and pandan. For DPPH scavenging, H2O2 scavenging, FRAP scavenging, ABTS reduction activities, PanJe resulted IC50 14.69 ¼g/mL, 27.70 ¼g/mL, 7.09 ¼g/mL, and 411.28 µg/mL, while ginger yielded IC50 7.76 ¼g/mL, 13.23 μg/mL, 4.94 ¼g/mL ,and 125.95 respectively. Otherwise, the highest total phenolic and flavonoid of panje were shown at 1.60 ± 0.26 µg QE / 100% extract and 8.67 ± 0.80 µg QE/100% extract respectively. Based on these results, PanJe, pandan and ginger are concluded as an active natural product because it exhibited antioxidant activities from two mixed compounds.
