Abstract

Anthocyanins in Korean pigmented rice(Oryza sativa var. Suwon 415) were analyzed to develop value-added natural pigment from rice. The pigment extracted with 1% HCl in methanol was determined as anthocyanins by characteristic absorption spectra in UV-visible ranges showing maximum absorbance at 280 ㎚ and 530 ㎚. Two aglycones from acid-hydrolyzed anthocyanins were identified as cyanidin and malvidin by their R_f values in several developing solvents, spectral properties, and ¹H-NMR analysis. Sugar moiety was determined as monoglucose by paper chromatography. The main anthocyanins in Korean pigmented rice were tentatively identified as cyanidin-3-glucoside and malvidin-3-glucoside.
