Glaucarubolone glucoside, a potential fungicidal agent for the control of grape downy mildew

A methanol extract of Castela emoryi was active as both a preventive and a curative agent against grape downy mildew infestation. 15-Glucopyranosyl-glaucarubolone (1) was identified as the active constituent. In the same assay holacanthone (2) was found to be phytotoxic and glaucarubolone (3) was in...
