Antioxidative phenolic glycosides from sage (Salvia officinalis).
An investigation of Salvia officinalis L. has led to the isolation of three new phenolic glycosides, 6-O-caffeoyl-beta-D-fructofuranosyl-(2-->1)-alpha-D-glucopyranosid e (1), 1-O-caffeoyl-beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyrano side (2), and 1-O-p-hydroxybenzoyl-beta-D-apiofuranosyl-(1-->6)-beta-D-glucop yranos ide (3). Elucidation of the structures of 1-3 was based on the interpretation of FABMS and 1D and 2D NMR spectra. Compounds 1 and 2 were found to be moderately active as antioxidants in the DPPH test and metmyoglobin test.
