Antimicrobial activities of aucubin, an iridoid glycoside, were investigated. Gram-positive bacterium, S. aureus appeared to be more sensitive to aucubin's aglucone, aucubigenin than Gram-negative, E. coli did. Antimicrobial activities produced by aucubigenin may result in part from the inhibition of RNA and protein biosyntheses in bacterial cells. The conversion of aucubin iridoid glycoside into aucubigenin, an aglucone, appears to be a prerequisite step to exhibit the antimicrobial activities.

Aucuba japonica has variable pharmacological effects such as hepatoprotective, choleretic, hemodynamic, antimicrobial, and anti-inflammatory activities. This study was performed to investigate the effects of Aucuba japonica extract on oral wound healing. Aucubin was extracted from Aucuba japonica, and injected on either side of buccal mucosa of male mice. Artificial full thickness wounds were made on the site with 1.5 mm biopsy punch under sterile technique. The specimens had taken on day 1, 3, and 5 with 4 mm biopsy punch. Light microscopic examination and quantitative histologic analysis were performed for reepithelization, inflammatory cell infiltration. Reepithelization of the aucubin (0.1%) group was earlier than the control group. And the number of inflammatory cells of the aucubin group was lesser than the control group. In view of the results so far achieved, the aucubin extracted from Aucuba japonica may be useful for oral wound healing and it can be applied as a topical agent on the oral wound. Further research should be performed on the mechanism of aucubin on oral wound healing and proper formulation for effective topical agents.
