PURPOSE:To provide on anti-mutagenic agent and the superoxide dismutage-like active food material containing as active ingredients tea catechin compounds obtained by extracting tea leave with water, an alcohol or their mixture as an extraction solvent. CONSTITUTION:The anti-mutagenic agent and the superoxide dismutage-like active food material contains as active ingredients tea catechin compounds, preferably epicatechin gallate [(-)EGGg], epicatechin gallate [(-)ECg] and epigallocatechin [(-)EGC], which are extremely strong in the anti-mutagenic activity against mutagenic agents Trp-P-1 and IQ, and in the active oxygen free radical-eliminating action, namely the superoxide dismutage(SOD)-like activity, are extremely low in toxicity, are safe for human bodies, and are produced by extracting tea leave with water, an alcohol or their mixture as extraction solvents. |
