Isolation of tyrosol the main phytotoxic metabolite produced by the edible fungus Agaricus litoralis

The phytotoxicity activity of EtOAc extract obtained from Agaricus litoralis showed high on tomato (Lycopersicon esculentum L.) leaves. A well-known phytotoxic metabolite: tyrosol [2-(4-hydroxyphenyl)-ethanol], was isolated and identified A. by spectroscopic methods. Phytotoxic tested seven agrarian plants: eggplant (Solanum melongena L.), fig (Ficus carica apricot (Prunus armeniaca peach persica (L.) Batsch), lemon (Citrus limon Osbeck), Cucurbita (Cucurbita grapevine (Vitis vinifera two wild willow oak (Quercus phellos blackberry (Rubus fruticosus using the leaf puncture assay, it weak phytotoxicity. highest effect observed grapevine, apricot, peach, cucurbita at 1 mg/ml; moderately eggplant, less fig, no necrosis Tyrosol has been previously microorganisms, fungi, plants, this being first record as a metabolite
