PURPOSE: Anthocyanidin and anthocyanins made from Schizandrae Fructus pigment are provided to obtain Cya-3-0-rutinoside, Cya-3-0-glucoside, and Cyanidin by acid-decomposing Cya-3-0-xylrut and a standard pigment composition in which single or 2-4 kinds of pigment are mixed. CONSTITUTION: A method for preparing a standard pigment composition comprises the steps of: adding HCl and trifluoroacetic acid(TFA) to Schizandrae Fructus fruit juice in order to become 2-4 mole; heating an acid additive solution for decomposition so that Cya-3-0-rutinoside becomes Cya-3-0-glucoside, Cya-3-0-xylrut, and Cyanidin; fractionizing the heated material with Isoamyl butanol to fractionize anthocyanidin and anthocyanins; and concentrating Isoamyl butanol fractions, and quick freezing and drying the fractions. |
