description Three new 4-hydroxy-benzoic acid derivatives, 4-methoxy-3,5-bis-(3-hydroxy-3-methyl-1-butenyl)benzo-ate, 3-hydroxy-2-(1-hydroxy-1-methylethyl)-2,3-dihydrobenzofuran-5-carboxylic acid, and 3-hydroxy-2-(1-hydroxy-1-methylethyl)-2,3-dihydrobenzofuran-5-carboxylic acid methyl ester together with eight known compounds, have been isolated from the stems of Piper hispidum. Their structures were elucidated by a detailed spectroscopic analysis. In addition, the cytotoxicity of seven isolated compounds has been evaluated, revealing a moderate activity for three derivatives of dillapiole.
