Description
Summary:Indonesia has an abundance of pigmented rice cultivars with high nutritional value. The purpose of this study was to identify and characterize the phytochemical profiles, anthocyanin properties, and biological activities of endogenous Indonesian black rice (Oryza sativa L.) cultivars from Java and East Nusa Tenggara (NTT) Islands. Thirteen black rice cultivars from eastern Nusa Tenggara and West, Central, and East Java were examined. The secondary metabolites of the black rice samples included flavonoids, tannins, phenolics, quinones, glycosides, anthraquinones, leucoanthocyanidins, alkaloids, and proteins. According to the FRAP (ferric reducing antioxidant power) assay, various levels of antioxidant activity were present. The results of an alpha amylase inhibition assay indicated that the black rice samples might have antidiabetic properties. We conclude that the Java and NTT endogenous black rice cultivars have rich phytochemical compounds with high nutritional value, and that their antioxidant and antidiabetic biological activities can promote a healthy life.
