Orchinol is a 9,10-dihydrophenanthrene, a type of phenanthrenoid. It can be isolated from infected Orchis militaris and infected Loroglossum hircinum^[1] with Rhizoctonia repens.^[2] This molecule has a phytoalexin effect. It reduces the growth of Cattleya aurantiaca seedlings^[3] and has an antifungal activity.^[4]
