Parijoto Muria (Medinilla javanensis) is a rare plant with many benefits because it contains secondary metabolites that act as natural antioxidants. This study aims to analyze the potential of Medinilla javanensis secondary metabolites as natural antioxidants through an ethno-STEM review. The research was conducted in Parijoto garden, located at 1100 meters above sea level in the Muria Mountains, Colo Village, Dawe District, Kudus Regency. The research instrument used was observation sheets and interviews with parijoto farmers. The data obtained were then tested for antioxidants and analyzed scientifically based on the ethno-STEM review. The results obtained are known to plant Parijoto Muria (Medinilla javanensis) has an IC50 value of 11 g/ml with the “Strong” category. The ethno-STEM review showed that parijoto contains red anthocyanin pigments that can be used as a natural food coloring. Besides being a dye, anthocyanins are also antioxidants because they belong to the flavonoid group, effective for inactivating free radicals and peroxyl. Based on data analysis, it can be concluded that parijoto contains secondary metabolites with intense antioxidant activity.
