Isolation and Identification of Anthocyanin Pigments in Black Rice
검색

    초록·키워드

    Anthocyanin pigments in black rice (Oryza sativa L., Indica type) were isolated and purified by thin-layer chromatography on reversed-phase ODS plate and Amberlite XAD-7 column chromatography. Further separation by preparative HPLC on a Develosil ODS-10 column, and GC analysis of enzymatic hydrolysates, and NMR (^{1}H- and ^{13}C-NMR) spectroscopic measurement were used for the identification. Two major pigments and two minor pigments were present in black rice seeds extracted with 0.5% trifluoroacetic acid (TFA) in 95% ethanol. Among them, cyanidin-3-O-β-D-glucoside and peonidin-3-O-β-D-glucoside as two major pigments were identified. Key words: black rice, chromatographic and NMR techniques, anthocyanins
