Effective and alternative strategies to control methicillin-resistant Staphylococcus aureus (MRSA) are consistently needed. Previous study presented that 7,10-epoxy-octadeca-7,9-dienoic acid (EODA) was produced from 7,10-dihydroxy-8(E)-octadecenoic acid through one-step heat treatment. Further studies confirmed that EODA was highly active against broad range of pathogenic bacteria including MRSA, promising development of a novel antibacterial agent to control MRSA. However, there are some practical huddles for industrialization of EODA, especially high cost for fine purification. To address this problem, this study was focused on determination of any changes in the antibacterial activities of EODA when used as a crude extract. As a result, any significant changes in the antibacterial activities of EODA was not detected and additional synergistic effect for commercial antibiotics on antibacterial activity was sustained as it was.
