This study was conducted to investigate the new candidates of natural preservatives, modified by based on the Korean medical prescription. We created 4 candidate extracts with different solvents. The crude water extract JBTP01 and JBTP02 showed weak antibacterial activities. Otherwise, 70% EtOH extract JBTP03 and MeOH extract JBTP04 showed wide antibacterial spectrum. Both were shown strong antibacterial activity to E. coli. JBTP03 was also effected bacteria C. albicans. Compared the antibacterial activities with methylparaben, commonly used syntetic antiseptic, and 3 natural preservatives in market. JBTP03 and JBTP04 showed similar modality of antibacterial activity spectrum. In other words, JBTP03 and JBTP04 had strong possibility to be new natural preservatives. Further study need to be done to use JBTP03 and JBTP04 for natural preservatives in cosmetics.
