초록
Antimicrobial activity of Mokdan bark (Paeonia suffruticosa ANDR) was investigated. Methanol extract of dried Mokdan 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 L. monocytogenes, and E. coli at 500 μg/disc. Ethylacetate fraction was further fractionated into 3 fractions by silica gel column and thin layer chromatography (TLC). The results showed that ethylacetate fractions No. 1 and 2 had the highest antimicrobial activity. They were mixed again, reseparated, and 3 fractions were obtained. Among them, No. 1 had the highest inhibitory effect on the microorganisms, No. 1 fraction was identified as isobutyl isopentanoate by HPLC, and GC-MS.
