Objective: These volatile components were extracted from 5 species flowers of Michelia figo

Magnolia liliflora

Gardenia jasminoides

Agastache rugosa

and Rosa multiflora

this research will provide scientific proof for the search of anti-oxidation activities and antimicrobial activities to empolder these natural resources. Method: These volatile components were extracted from flowers of M. figo

M. liliflora

G. jasminoides

A. rugosa

and R. multiflora respectively by steam distillation. Five species volatile components were investigated about antimicrobial activities of scavenging effect for ·OH

and were evaluated to anti-oxidation activities using minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) methods. Result: Five species volatile components have obvious action to anti-oxidation activities of scavenging effect for ·OH

and inhibited the growth of testing bacterias and sterilized them. Conclusion: Their anti-oxidation activities showed M. figo ﹥ A. rugosa ﹥ M. liliflora ﹥ G. jasminoides ﹥ R. multiflora . The antimicrobial results showed A. rugosa ﹥ M. liliflora ﹥ R. multiflora ﹥ G. jasminoides ﹥ M. figo .
