Free Radical Scavening and inflammatory of the methanol extracts, which were prepared from 6 difffrent bran of rice, were evaluated to investigate bioactive substances. Among them, the extract of C3GHibyeo and Heugjinjubyeo showed strong DPPH scavening activities (73.25% and 50.38% at 0.4 mg/ml, respectively). The extract of C3GHibyeo and Heugjinjubyeo showed strong thrombin inhibition activities (258.76% and 243.52% inhibition at 5 mg/ml, respectively). The result of antibacterial activity by Zone assay showed that C3GHi rice extract $(250{\mu}g\;and\;500{\mu}g)$ inhibited attachment of Helicobactor pylori on the ATCC48504 and COO1 cell line. But no effect on the SEO cell line. Cytotoxicity of blackish purple rice extract on the H. pylori doesn't showed. These result support a functional superiority of rice-base livelihood, and suggest that the development of healthy food using functional ingredients of rice is possible.
