Corn silk and rosella flowers are plants whose utilization can still be developed, especially in the food sector. The secondary metabolites found in both plants serve as a source of natural antioxidants to combat free radicals. This study aims to examine the effect of variations in drying methods on the antioxidant activity content of a combination tea of corn silk and rosella flower. Antioxidant level test using the DPPH method. Analysis of antioxidant data in the form of determining the IC50 value using probit linear regression analysis. The study results show that drying using the oven method has an IC50 of 83 ppm while drying in the sun has an IC50 of 121 ppm. Research findings indicate high antioxidant levels in a combination of corn silk and rosella flower tea through oven drying and moderate antioxidants in direct drying in the sun.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
