Antifungal and antioxidative ability in Lamiaceae herbs

Y. Matsubara, Y. Yamashita, J. Liu
Lamiaceae herbs have antifungal uses in aspects of medicine and food. However, the antifungal and antioxidative effects of Lamiaceae herbs on plant diseases remain unclear. In this study, the antifungal and antioxidative abilities of 10 species of Lamiaceae herbs were determined. Extracts (0.5 and 2% w/v) of shoots of several herbs suppressed the propagation of Fusarium oxysporum f. sp. asparagi in Czapek-Dox medium in vitro. In this case, shoot extracts of oregano (Origanum vulgare L.), lemon balm (Melissa officinalis L.), and sage (Salvia officinalis L.) showed high suppression in their indices of Fusarium propagation: 50.5, 41.5, and 32.7, respectively. As for the antioxidative aspects, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity was relatively at higher levels in sage, oregano, lemon balm, and hyssop (Hyssopus officinalis L.). From these findings, it is suggested that some of the Lamiaceae herbs had high antifungal and antioxidative properties.
