Phytochemical Screening and Antibacterial Activity of Taxus baccata L. against Pectobacterium spp. and Dickeya chrysanthemi

The yew tree (Taxus baccata L.) is considered in folklore a symbol of immortality due to its qualities longevity and regeneration. Despite poisonous reputation, the has long history medicinal use, particularly form extracts from leaves bark. In work presented herein, gas chromatography–mass spectrometry (GC–MS) chemical profiling was applied aqueous ammonia/hydromethanolic several plant organs T. baccata, leading identification different bioactive compounds than those previously characterized by high-performance liquid chromatography with tandem mass (HPLC–MS/MS) other extraction media. leaf ammonia extract rich 2-hexylthiophene 3-O-methyl-d-fructose; 9-octadecenoic hexadecanoic acid were main constituents bark extract; fruit hydromethanolic contained methyl 2-O-methyl-α-d-xylofuranoside, 1,3-dioxolane derivatives, erysimoside. antimicrobial activity assayed against four bacterial pathogens responsible for soft rot blackleg diseases potatoes, viz. Pectobacterium carotovorum subsp. carotovorum, atrosepticum, parmentieri, Dickeya chrysanthemi, resulting minimum inhibitory concentration (MIC) values as low 187 μg·mL−1. Bioassays on potato slices confirmed efficacy at this dose when preventive treatment before artificial inoculation P. carotovorum. view high activity, these may find application integrated pest management Pectobacteriaceae (SRP) diseases.
