Resumen:
Abstract An antibiotic called fragarin showing activitiesagainst bacterial and fungal plant pathogens was isolated andpurified by FPLC chromatography from the soluble fraction ofstrawberry leaves. The molecular weight value determined bymass spectrometry is 316 Da. Fragarin remains fully active afterprotease treatment or alkaline hydrolysis at 100≥C for 20 min.Biological and chemical analyses suggest that fragarin may be anew type of an antimicrobial preformed compound ^ phytoanti-cipin ^ and would constitute a primary non-specific barrier ofstrawberry defense.
