This study evaluated the in vitro antimicrobial effect of 3β-acetoxy-norlup-20-one (1) and 3-chloro-4α,14α-dimethyl-5α-cholest-8-ene (2), triterpene derivatives from Euphorbia officinarum latex against fungal and bacterial phytopathogens. Results showed that although mycelial growth of several strains of Verticillium dahlia, and Fusarium oxysporum fsp. melonis and Penicillium expansum was affected only moderately, the two compounds were able to reduce highly conidia formation and germination…
