Isolation and Structural Identification of Minor Constituents from Sasa borealis

  • Published : 2005.09.01

Abstract

Compounds of (+)-5,5'-dimethoxylariciresinol (1) and (3S,5R,6S,7E)-5,6-epoxy-3-hydroxy-7-megastigmen-9-one (2) were isolated from an EtOAc extract of the whole plant of Sasa borealis (Hack.) Makino (Gramineae) for the first time in the present investigation. The structures of compounds were identified by analysis of spectral data including 1D- and 2D-NMR spectra as well as by comparison of their data with the published values. These compounds have never been isolated previously from the family Gramineae.
