Controlling anthracnose by means of extracts, and their major constituents, from Brosimum rubescens Taub.

•Extracts of less polarity from B. rubescens displayed significant antifungal activity.•Two coumarins (xanthyletin and 7-demethylsuberosin) were isolated from antifungal extracts of B. rubescens.•A chromatographic method to detect and quantify both coumarins is described.•Xanthyletin and 7-demethylsuberosin exhibited in vivo and in vitro strong antifungal activity.•7-Demethylsuberosin was metabolized slowly by C. gloeosporioides to marmesin and decursinol.
