In DPPH radical and nitric oxide scavenging ability, the extract of lowest temperature condition(40-15H ; 15 hours at 40℃ for drying) exhibited highest activity. The total phenolic and flavonoid contents of each extracts were found to be 120.4~193.3 mg/g and 86.91~94.55 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℃ for drying) was exhibited MIC of slightly low level against some strains. And every extract showed fine cell viabilities(101.7~122.9%) 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.
