Abstract
Abstract Chemical component analysis of the root parts of P. odoratissimus led to the isolation of two phenolic compounds, four lignan type compounds plus a new benzofuran derivative. Among them, pinoresinol and 3,4- bis (4-hydroxy-3-methoxybenzyl) tetrahydrofuran showed strong antioxidative activities when BHA was used as a standard in the thiocyanate method. The new compounds were identified as 4-hydroxy-3-(2′,3′-dihydroxy-3′-methylbutyl)-benzoic acid methyl ester and 3-hydroxy-2-isopropenyl-dihydrobenzofuran-5-carboxylic acid methyl ester, by spectroscopic analysis.
