Abstract
Kecombrang (Etlingera elatior) has bioactive compounds such as phenols and flavonoids as antioxidants. This study aims to determine the effect of temperature and time drying on total phenols, total flavonoids, and phytochemical compounds from stem and leaves kecombrang powder using the cabinet dryer method. This study uses a completely randomized design (CRD). Factors tested in this study were kecombrang plant parts (stems and leaves) and drying temperature (50°C, 60°C, and 70°C). The variables observed in this study were total phenols, total flavonoids, water content and phytochemical compounds from stem and leaves kecombrang powder. Quantitative research results showed that kecombrang leaf powder with a drying temperature of 70°C had total phenols, total flavonoids and water content respectively of 35.89 mg TAE I g, 2.132 mg QE I g and 5.557%. Meanwhile, kecombrang stem powder with a drying temperature of 60°C has a total phenol, total flavonoid and water content respectively of 6.030 mg TAE I g, 0.160 mg QE I g and 7.873%. The results of phytochemical testing showed that the positive kecombrang leaf powder contained alkaloid, flavonoid, saponin, steroid, tannin, phenol and negative compounds containing glycoside compounds while the positive kecombrang stem powder contained alkaloid compounds, flavonoids, triterpenoids and phenols and negatively contained glycoside compounds, while kecombrang stem powder positively contained alkaloid compounds, flavonoids, triterpenoids and phenols while negatively containing tannins, saponins and glycosides.
