摘要：

Methanol extracts of rice hull from Katakutara (long-life) and Kusabue (short-life) seeds exhibited antioxidative activity stronger than that of α-tocopherol. Fractionation of the crude extracts on Amberlite XAD-2 column followed by antioxidative assay revealed that both samples possessed strong antioxidative constituents in methanol-water (50:50, 75:25) fractions. HPLC separation of 50:50...
