Antimicrobial activity of Jakyak(Paeonia japonica var. pilosa N_AKA1) was investigated. Methanol extract of dried Jakyak was fractionated to hexane, chloroform, ethylacetate, butanol and aqueous fraction. Ethylacetate fraction among these fractions showed the highest inhibitory effect on the microorganisms such as B. subilis, B. subtilis, L. monocytogenes, and V. parahaemolyticus at 500 ㎍/disc. Ethylacetate fraction was further fractionated into 11 fractions by silica gel column and thin layer chromatography(TLC). The results showed that ethylacetate fractions No. 3, 4 and 5 had the highest antimicrobial activity. They were mixed again, re-separated, and 5 fractions were obtained. Among them, the highest inhibitory effect was obtained in No. 3 fraction, which was identified as cetyl alcohol by HPLC and GC-MS.
