Six new flavonolignans from Sasa veitchii (Carr.) Rehder
摘要:
From dry leaves of Sasa veitchii (Carr.) Rehder, six new flavonolignans 4-9, each consisting of a tricin unit linked to a guaiacylglyceryl derivative were isolated and their structures were determined on the basis of spectroscopic data and chemical evidence. These flavonolignans were found to be three pairs of stereoisomers. (C) 2003 Elsevier Ltd. All rights reserved.
