Anthocyanin Content Characterization on Pigmented Local Rice as Genetic Resources of Functional Food

Abstract

<p>Local varieties of pigmented rice are highly valuable genetic resources as a functional food in the future. Pigmented rice contains anthocyanins which function as nutrient bioactive components, called antioxidants. The aim of this research was to characterize anthocyanin content on 27 accessions of pigmented local rice, 2 varieties of released red rice varieties (Aek Sibundong and Inpari<br />24), and 1 control varieties of white rice, Ciherang. The content of anthocyanin was analyzed by using High Performance Liquid Chromatography (HPLC) with cyanidin-3-glucoside as a standard. The results showed that local rice Aen Metan and Melik had the highest anthocyanin content were reached 0.7953 mg/g and 0.7806 mg/g. These content were higher than 2 released red rice varieties, Aek Sibundong and Inpari 24 which had anthocyanin content reached 0.6496 mg/g and 0.4423 mg/g, respectively. Aen Metan and Melik were local black rice varieties and frequently have used as a parent in the breeding program. The white rice as control, Ciherang was showed the lowest anthocyanin content. Four pigmented local rice, Baliman Putih, Sari Kuning, Karamanting, and Iden had higher anthocyanin content than the two released red rice breeding varieties.</p>
