Antioxidant activity of panJe tea combination of pandan (Pandanus amaryllifolius) and jahe (Zingiber officinale)

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 μg/mL, 27.70 μg/mL, 7.09 μg/mL, and 411.28 µg/mL, while ginger yielded IC50 7.76 μg/mL, 13.23 μg/mL, 4.94 μg/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

Antioxidant activity of panJe tea combination of pandan (Pandanus amaryllifolius) and jahe (Zingiber officinale)

Herbal tea is popular because of its potential as medicine, a combination of herbal ingredients promises to produce new colors, flavors, and tastes. This study aimed to determine the antioxidant activities of an herbal tea combinations (pandan and jahe) called PanJe and compared it to the antioxidant single herbal tea namely Pandan tea (0.5 g dried pandan) and Ginger tea (2 g dried ginger). The PanJe tea was a combination of 0.5 g pandan tea and 2 g ginger tea. Pandan tea, ginger tea and PanJe tea are soaked for 5 minutes in 200 mL of boiling water. The antioxidant activities were assayed namely 2,2-Diphenyl-1-picrylhydrazyl (DPPH), hydrogen peroxide (H2O2), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) free radical scavenger, and Ferric Reducing Antioxidant Power (FRAP) assay. The flavonoid content used Quercetin Equivalent (QE), while the total phenol content used Gallic Acid Equivalent (GAE). DPPH, H2O2, ABTS scavenging activities and FRAP assay of PanJe tea was presented in median inhibitory concentration (IC50) value respectively 14.69, 27.70, 4.11 and 7.09%, while pandan tea resulted in IC50 value of 23.63, 27.19, 4.54 and 12.86%, and ginger tea resulted in IC50 value of 7.76, 13.23, 1.26 and 4.94%, respectively. These assays proved ginger tea had the highest antioxidant activities compared to PanJe tea and pandan tea which had the lowest antioxidant activities. Total phenolic and flavonoid of PanJe respectively were 0.035 µg GAE/mg and 0.006 µg QE/mg of PanJe tea meanwhile pandan tea respectively contain 0.002 µg GAE/mg, 0.0003 µg QE/mg of pandan tea and ginger tea contained 0.118 µg GAE/mg and 0.036 QE/mg of ginger tea. Compared to PanJe tea and pandan tea, ginger tea has the highest total phenol and flavonoid content. Conclusion ginger tea is higher antioxidant activities also a higher phenol and flavonoid content than PanJe tea

Antioxidant Activity of TEMON (Clitoria ternatea and Citrus sp.) as an Infused Herbal Tea

Many people around the world believed that herbal tea had a lot of antioxidants contained in it, thus it was widely drunk all over the world. However, the antioxidant capacities of herbal tea may be various because it is affected by the usage of different plants as its primary ingredient. As a result, this study examines the antioxidant activity of herbal tea made from dried Citrus sp. and Clitoria ternatea flower petals. The antioxidant potential was assessed by performing a DPPH and H2O2 scavenging activity assay on 2,2-diphenyl-1picrylhydrazyl (DPPH) and hydrogen peroxide (H2O2) scavenging activity assay, total phenolic, and flavonoid content assay, ABTS reduction, and FRAP assay. This study showed that pure telang (Clitoria ternatea) herbal tea has antioxidant properties. Dried Telang (Clitoria ternatea) tea had the highest activity of antioxidants as we refer to the results of it had the highest activity value in DPPH, ABTS, and FRAP assay and also had the lowest IC-50 value. Followed by TEMON infusion which showed the second-highest antioxidant activity after pure telang infusion. The decrease in antioxidant activity in the mixture of telang and lemon was due to the mixture of lemons which tended to have the lowest antioxidant activity among the three types of infusions tested. The addition of dried lemon has the aim of enhancing the flavor of the tea infusion
