Abstract

In DPPH radical and nitric oxide scavenging ability, the extract of lowest temperature condition(40-15H ; 15 hours at $40^{\circ}C$ for drying) exhibited highest activity. The total phenolic and flavonoid contents of each extracts were found to be $120.4{\sim}193.3\;mg$/g and $86.91{\sim}94.55\;mg$/g respectively. It is shown that 40-15H was the highest content in each compound. In antimicrobial activity, a lower drying temperature conditions were found to be more strong activities in disc diffusion assay and each extracts showed MIC of identical level against every tested microbial strains. However 100-2H(2 hours at $100^{\circ}C$ for drying) was exhibited MIC of slightly low level against some strains. And every extract showed fine cell viabilities($101.7{\sim}122.9%$) against RAW 264.7 cell. In anti-proliferation activity against AGS, each extract showed a similar inhibition activity. However in anti-proliferation activity against HeLa, a lower drying temperature conditions showed more strong activities.
