Phenylpropanes from Acorus tatarinowii

Abstract

In addition to a number of known compounds, four new phenylpropanes isoacoramone, (cis) epoxyasarone, (threo) 1′,2′-dihydroxyasarone and (erythro) 1′,2′-dihydroxyasarone were obtained from the roots of Acorus tatarinowii (“Shi-Chang-Pu” in Chinese). The later two isomers were obtained as a mixture. However, all the chemical shifts of the protons and carbons for these two components were assigned by 1D- and 2D-NMR techniques.
