Polygodial, the fungitoxic component from the Brazilian medicinal plant Polygonum punctatum
TL;DR: The dichloromethane extract of the aerial parts of this plant showed strong activity in a bioautographic assay with the fungus Cladosporium sphaerospermum and the bioassay-guided chemical fractionation afforded the sesquiterpene dialdehyde polygodial as the active constituent.
