Abstract

The allicin and alliin contents of Allium obliquum L. ethanol extract were analyzed by liquid chromatography coupled with mass spectrometry method. Additionally, the ability of A. obliquum to inhibit the growth of Botrytis paeoniae Oudem. on the nutritive medium was assessed. The in vitro fungicidal activity of A. obliquum was studied by the ultrastructural changes induced in the conidia and sclerotia of B. paeoniae treated with the plant extract in minimum inhibitory concentrations.

Key words: Allicin, alliin, antifungal activity, electron microscopy, minimum inhibitory concentration.
