Abstract
One of the plants known to have medicinal properties to cure various diseases is Tapak Dara (Catharanthus roseus). Tapak Dara leaves are known to contain flavonoids and tannins which have anti-inflammatory and analgesic effects). Herbal drinks generally have a bitter taste so it is necessary to add sweeteners that are also safe for diabetics to consume, one of which is Stevia (Stevia rebaudiana B.). This study aimed to determine acceptable formulation in brewed drinks by panelists and to determine the percentage content of functional compounds as alternative analgesics in brewed drinks produced. The method used in this research; are making powdered Tapak Dara leaves and Stevia leaves, making brewed drinks, organoleptic testing, and testing the content of functional compounds in brewed drinks. The observation parameters in this study include water content analysis, pH measurement, analysis of antioxidant content, flavonoid content (quercetin), tannin content, and analysis of stevioside content in brewed drink samples. The results of this study were obtained the best formulation based on the panelists’ preference level, namely, the treatment is A3. The results of the analysis of the total phytochemicals content in brewed drinks obtained are water content of 5.287%, pH value of 5.5, quercetin content of 6.0379 mg/g, tannins content of 0.03%, antioxidant content of 320.47 ppm, and stevioside content of 2.16 mg/ml. This research concludes that the most preferred formulation of brewed drink by the panelists is the A3 treatment with a composition of 25% Tapak Dara leaves and 75% Stevia leaves and the total phytochemical content in brewed drinks obtained were water content of 5.287%, pH value of 5.5, quercetin content of 6.0379 mg/g, tannin content of 0.03%, antioxidant content of 320.47 ppm, and stevioside content of 2.16 mg/ml.
