Antifungal and insect antifeedant 2-phenylethanol esters from the liverwort Balantiopsis cancellata from Chile.
A chemical study of a dichloromethane extract of Balantiopsis cancellata led to the isolation of four known 2-phenylethanol esters (1-4) and a phenylethanediol benzoate (5). Antifeedant activity toward Spodoptera littoralis (disk-choice bioassay) and growth inhibition of the phytopathogen Cladosporium herbarum in TLC-bioautography assays were determined. The results show that the antifeedant and antifungal activity of the extract is attributable mainly to the trans-beta-methylthioacrylate 4.
