The Bark of the Spruce <i>Picea jezoensis</i> Is a Rich Source of Stilbenes

Stilbenes are plant phenolic secondary metabolites that show beneficial effects on human health and possess high antifungal activity against plant pathogens. Currently, a search for plant sources with high stilbene levels is relevant, since stilbene content in various plant species can vary substant...
